Opinion by
Judge HAWTHORNE.Defendant, Mark Anthony Montez, appeals the judgment of conviction entered on jury verdicts finding him guilty of two first degree burglary counts, two possession of a weapon by a previous offender counts, one theft count, and six habitual criminal counts based on prior felony convictions. We affirm the convictions and remand the case for the court to correct the mittimus because we conclude that the burglary convictions merge.
I. Factual Background
The following facts, viewed in the light most favorable to the prosecution, were established at trial. Defendant broke a home's back window, entered and ransacked the residence, and fled with approximately $150 and a gun case containing two unloaded shotguns.
II. Batson Challenge
Defendant contends that reversal is required because the trial court failed to conduct a proper analysis under Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 *11L.Ed.2d 69 (1986). We discern no basis for reversal.
A. Background
Apparently relying on Batson, defendant objected after the prosecution used peremptory challenges to excuse the only two jury panel members with Hispanic surnames. The prosecutor stated he excused one member because, in response to a question about who her hero was, she chose herself. He found her answer "very odd and eccentric ... and [it] did not go to the values that [he] thought would make a good juror." The prosecutor explained that he exeused the see-ond panel member because she "exhibited very poor body language in response to questions about reasonable doubt ... [and] was shaking her head with the defense." He further opined that she appeared Caucasian and might be married to someone with a Hispanic surname.
After the court asked defense counsel whether he "would ... like to follow-up," he responded that it was inappropriate to ask about a panel member's race. He further stated that she "looked Hispanic to [him]," reiterated that the prosecutor excused the only two Hispanics on the jury panel, and emphasized that defendant is also Hispanic.
The court observed that the prosecutor used peremptory challenges to strike the only two jury panel members with Hispanic surnames and noted that defendant also has a Hispanic surname. However, it concluded, "I do not find that two people make a Batson challenge. [The prosecutor] has given us no race-related reasons for that."
B. Law
Trial courts must apply a three-step process in evaluating a Batson challenge. See People v. Robinson, 187 P.3d 1166, 1172 (Colo.App.2008). First, the party opposing the challenge must make a prima facie case of racial discrimination. Second, if the opponent meets that requirement, the burden of production shifts to the challenge's proponent to offer a race-neutral explanation. Third, if the proponent meets that burden, the opponent must have the opportunity to rebut the prosecutor's explanation, and the trial court must determine whether the opponent has proved purposeful racial discrimination. Id.; People v. Vieyra, 169 P.3d 205, 211 (Colo.App.2007). "[TThe ultimate burden of persuasion regarding racial motivation rests with, and never shifts from, the opponent of the strike." Robinson, 187 P.3d at 1172 (quoting Purkett v. Elem, 514 U.S. 765, 768, 115 S.Ct. 1769, 131 L.Ed.2d 834 (1995)).
We review de novo a trial court's rulings on the inquiry's first and second steps, and we defer to its ultimate resolution in step three, reversing only for clear error. Vieyra, 169 P.3d at 211.
C. Analysis
Contrary to defendant's interpretation, we read the trial court's statement, "I do not find that two people make a Batson challenge," to mean that the court, after conducting a three-step analysis, did not find that the two panel members were challenged for discriminatory reasons. The court made a specific factual finding, not a general legal conclusion. See People v. Collins, 187 P.3d 1178, 1184 (Colo.App.2008) ("[the striking of a single potential juror for a discriminatory reason violates the Equal Protection Clause"). We discern no basis for reversal because the trial court conducted a Batson analysis and concluded that defendant had not carried his burden to prove purposeful racial discrimination.
First, defendant offered his reasons for objecting to the prosecutor's peremptory challenges. Next, the prosecutor proffered race-neutral explanations for exercising the challenges. In response to the court's invitation to "follow up," defendant essentially repeated his objection that the two challenged Jurors were the "only two Hispanic people on the jury panel" but did not offer any other proof of purposeful racial discrimination. When the trial court found that two people do not make a Batson challenge and stated, "Ithe prosecutor] has given us no race-related reasons for [the peremptory challenges]}," it engaged in the third step of its Batson analysis. Having heard the prosecutor's race-neutral explanation, and defendant's rebuttal, the court concluded that the explana*12tion was credible and defendant did not prove that the challenges were racially motivated.
Because step three involves determining credibility, the trial court is in a superior position to evaluate whether discrimination occurred, and absent clear error we will not substitute our judgment for the trial court's. See Snyder v. Louisiana, 552 U.S. 472, 477, 128 S.Ct. 1203, 170 L.Ed.2d 175 (2008) (trial court has pivotal role in evaluating Batson claims because the inquiry's third step involves evaluating the prosecutor's credibility, often discriminatory intent is best evidenced by the challenging attorney's demeanor, and race-neutral reasons for peremptory challenges frequently also invoke a juror's demeanor). We therefore conclude that the trial court did not clearly err in determining that defendant had not proved purposeful racial discrimination.
III. Evidence's Sufficiency
Defendant next contends that his first degree burglary convictions must be vacated because there was insufficient evidence that he was "armed" with a deadly weapon. We disagree.
A. Law
Appellate courts review de novo whether the evidence, viewed in the light most favorable to the prosecution, was "sufficient in both quantity and quality to sustain the convictions." Dempsey v. People, 117 P.3d 800, 807 (Colo.2005). It is the prosecution's burden to establish a prima facie case of guilt, which requires it to introduce "sufficient evidence to establish guilt-no more, no less." Id. (quoting People v. Bennett, 183 Colo. 125, 130, 515 P.2d 466, 469 (1973)). The evidence must be both "substantial and sufficient to support a conclusion by a reasonable mind that [the] defendant is guilty of the charge beyond a reasonable doubt." Bennett, 183 Colo. at 130, 515 P.2d at 469. The court must give full consideration to the jury's right to draw all justifiable factual inferences from the evidence. Id. The fact finder determines the evidence's weight. People v. McIntier, 134 P.3d 467, 471 (Colo.App.2005). An appellate court cannot sit as a thirteenth juror and set aside a verdict simply because it could have reached a different conclusion. Id. Where "reasonable minds could differ, the evidence is sufficient to sustain a conviction." People v. Rector, 226 P.3d 1170, 1176 (Colo.App.2009).
We therefore examine the evidence here to determine whether it reasonably satisfies the definition of "armed" to support the jury's first degree burglary verdicts.
B. Analysis
"A person commits first degree burglary if the person knowingly enters unlawfully ... in a building or cccupied structure with intent to commit therein a crime ... and if in effecting entry or while in the building or occupied structure or in immediate flight therefrom, the person ... is armed with ... a deadly weapon." § 18-4-202(1), C.R.S.2009. An unloaded shotgun is a deadly weapon. See § 18-1-901(8)(e)(I), C.R.S. 2009. The term "armed" is not defined by statute; however, Colorado case law requires that the deadly weapon must be "easily accessible and readily available for use by the defendant for either offensive or defensive purposes." People v. Loomis, 857 P.2d 478, 482 (Colo.App.1992) (quoting State v. Hall, 46 Wash.App. 689, 732 P.2d 524, 528 (1987)).
Here, the evidence showed that defendant removed a gun case containing two unloaded shotguns from the home. Witnesses testified that the gun case resembled a guitar case. There was no ammunition in the case, nor was any found on defendant's person. The evidence included two photographs of the gun case; one showing the case open with the two shotguns inside it and the other showing the case closed. Neither photograph revealed a lock or locking mechanism on the case, and there was no other evidence that the case was locked or otherwise rendered difficult or impossible to open while in defendant's possession.
Considering this evidence in the light most favorable to the prosecution, we conclude that the jury could reasonably have inferred that opening the case and making the shotguns available could have been accomplished reasonably quickly and would be no more *13difficult or time-consuming than accessing an unlocked guitar case's contents. Accordingly, we conclude that there was sufficient evidence to support a jury conclusion, beyond a reasonable doubt, that the deadly weapons were easily accessible and readily available for use by defendant.
We reject defendant's assertion that People v. Moore, 841 P.2d 320 (Colo.App.1992), requires a different conclusion. The division in Moore did not rely on the term "armed" as meaning "easily accessible and readily available for use" as adopted in Loomis. See Loomis, 857 P.2d at 482; Moore, 841 P.2d at 822-28. Although the Moore division noted that the defendant had not removed the weapons from a canvas sack, it did not decide whether the weapons were easily accessible and readily available. Instead, the division apparently relied on other statutory language as requiring that one must threaten another with the weapon to be guilty of first degree burglary. See Moore, 841 P.2d at 328. We agree with the Loomis division and decline to follow Moore See Loomis, 857 P.2d at 481 (under the "easily accessible and readily available" test, it is not necessary to analyze a defendant's willingness or present ability to use the firearm).
We also reject defendant's argument to the extent it asserts Loomis holds that deadly weapons enclosed in containers or otherwise limited in access are necessarily not easily accessible and readily available for use. See Loomis, 857 P.2d at 482. The division's statement in Loomis that the stolen firearms carried by the defendant "were not enclosed in containers or otherwise limited in access" merely bolsters its conclusion that the weapons were "clearly easily accessible and readily available for use by the defendant." Id. (emphasis added). In this case, we have concluded that the jury could have reasonably determined that the shotguns were easily accessible and readily available to defendant even though they were encased and thus, limited in access.
We further conclude that State v. Brown, 162 Wash.2d 422, 173 P.3d 245 (2007), relied on by defendant, is inapposite. There, the court's analysis is based on "[rlequiring both that the weapon be readily available and easily accessible, as well as a nexus based on the facts of the case, [to] limit{ ] the definition of being armed to those situations the statutes are aimed at controlling." Id. at 251. Our case law does not require a nexus between the crime and the weapon. Id. at 250; cf. Loomis, 857 P.2d at 482.
Finally, we reject defendant's argument that he was not armed with a deadly weapon because the guns lacked ammunition. The statutory definition of "deadly weapon" includes "a firearm, whether loaded or unloaded." § 18-1-901(8)(e)(I). " 'Firearm' means any ... shotgun ... capable or intended to be capable of discharging bullets ...." § 18-1-901(8)(h), C.R.S.2009. Moreover, an unloaded firearm can be used for offensive or defensive purposes.
Because there is sufficient evidence establishing that defendant was armed with a deadly weapon, we affirm defendant's first degree burglary convictions subject, however, to the merger analysis below.
IV. Merger
Defendant contends that his burglary convictions merge and his possession of a weapon by a previous offender (POWPO) convictions also merge. We conclude that defendant's two burglary convictions merge but not his two POWPO convictions.
A. Burglary
Defendant contends, the People concede, and we agree that his burglary convictions merge. See People v. Denton, 91 P.3d 388, 392 (Colo.App.2003) (trial court erred by entering more than one conviction based on identical evidence). Thus, we remand to the trial court to correct the mittimus.
B. POWPO
Defendant was charged and convicted of two POWPO counts because he possessed two shotguns removed from the home and had a prior felony menacing conviction within the prior ten years.
*141. Law
Section 18-12-108(1), C.R.8.2009, provides, "A person commits the crime of possession of a weapon by a previous offender if the person knowingly possesses, uses, or carries upon his or her person a firearm ... subsequent to the person's conviction for a felony....
Whether a defendant may receive a separate POWPO conviction for each firearm he possesses involves statutory interpretation subject to de novo review. See Leyva v. People, 184 P.3d 48, 50 (Colo.2008).
2. Analysis
The United States' and Colorado Constitutions' Double Jeopardy Clauses do not prohibit imposing multiple punishments for committing a single act where the General Assembly clearly intends to punish the same offense with more than one conviction and sentence. People v. Abiodun, 111 P.3d 462, 465 (Colo.2005).
Whether particular acts were committed is a factual question. Whether different acts constitute more than one offense and whether sufficient evidence exists to support multiple offenses are legal matters. If each legally distinct offense was charged with sufficient specificity to distinguish it from other offenses and there was sufficient evidence produced at trial to support convictions of each charge, general verdicts of guilt will be adequate to support multiple convictions. Id. at 471; People v. Mintz, 165 P.3d 829, 833 (Colo.App.2007).
In this analysis, we must determine whether the unit of prosecution prescribed by the legislature permits charging multiple offenses. Quintano v. People, 105 P.3d 585, 590 (Colo.2005). The unit of prosecution is the manner in which a eriminal statute permits the defendant's conduct to be divided into discrete acts for prosecuting multiple offenses by establishing whether the conduct consists of one or more violations of a single statutory provision. Mintz, 165 P.3d at 833.
In interpreting section 18-12-108(1)'s language, our primary task is to give effect to the legislature's intent. Id. We begin with the statute's language and its plain meaning, which we consider within the whole statute's context. Id.; Romanoff v. State Comm'n on Judicial Performance, 126 P.3d 182, 188 (Colo.2006). Under the statute, a convicted felon "commits the crime" when he "knowingly possesses ... a firearm." The phrase "a firearm" indicates that each firearm constitutes a separate statutory violation. See § 18-12-108(1). Thus, the statute's plain meaning supports imposing separate convictions for each firearm possessed.
By contrast, the federal counterpart to seetion 18-12-108(1) makes it "unlawful" for a convicted felon to possess "amy firearm." 18 U.S.C. § 922(g), 2009 (emphasis added). The word "any" creates an "unlimited, non-restricted phrase." Woellhaf v. People, 105 P.3d 209, 216 (Colo.2005). Thus, the federal statute only authorizes one conviction for possessing multiple firearms. See, e.g., United States v. Hodges, 315 F.3d 794, 798-99 (7th Cir.2003) (sufficient evidence to support defendant's conviction of one count of "being a felon in possession of firearms" upon proof that he received four guns). If the Colorado General Assembly had intended for only one conviction to enter regardless of how many firearms an offender possessed, it would have done so clearly, for example, by using the language employed in the federal statute.
Moreover, the statute's purpose is to "limit the possession of firearms by those who, by their past conduct, have demonstrated an unfitness to be entrusted with such dangerous instrumentalities." People v. Gallegos, 193 Colo. 108, 110, 563 P.2d 937, 989 (1977) (quoting People v. Trujillo, 178 Colo. 147, 150, 497 P.2d 1, 2-3 (1972)). Punishing possession of each weapon as a separate convietion effectuates this purpose. Thus, we conclude that each weapon possessed separately violates the statute and subjects the offender to a separate conviction. See Robinson, 187 P.3d at 1169 (affirming, without analyzing this issue, defendant's two POWPO convie-tions where two firearms were found in his vehicle).
V. POWPO Felony Classification
Defendant contends his two POWPO convictions must be reduced from class five to class six felonies. We disagree.
*15A. Law
POWPO is a class six felony, but it is a class five felony if committed within ten years of a conviction for a "felony involving the use of force or the use of a deadly weapon." § 18-12-108(2)(a), (c), C.R.8.2009.
B. Analysis
1. Use of Force
Defendant argues that felony menacing, the felony offense of which he was previously convicted, is not a "felony involving the use of force or the use of a deadly weapon" under section 18-12-108(2)(c). We disagree.
Statutory interpretation issues are legal questions subject to de novo review. See People v. Martinez, 780 P.2d 560, 561 (Colo.1989) (whether trial court correctly defined term "possess" was legal question).
Section 18-3-206(1) provides:
A person commits the crime of menacing if, by any threat or physical action, he or she knowingly places or attempts to place another person in fear of imminent serious bodily injury. Menacing ... is a class 5 felony if committed:
(a) By the use of a deadly weapon or any article used or fashioned in a manner to cause a person to reasonably believe that the article is a deadly weapon; or
(b) By the person representing verbally or otherwise that he or she is armed with a deadly weapon.
Our case law defines force to include "actual, applied physical force" and "compulsion by threatened violence." Gallegos, 193 Colo. at 110, 563 P.2d at 938-39. Because felony menacing is committed when a person knowingly places or attempts to place another in fear of imminent serious bodily injury by using or threatening use of a deadly weapon, it necessarily involves the threat of force. Thus, a POWPO conviction entered within ten years after a felony menacing conviction is a class five felony. See id. (attempted robbery by threat to blow up another's property is a felony that involves using force or violence under prior POWPO statute); see also People v. Jenkins, 198 Colo. 347, 349, 599 P.2d 912, 913 (1979) ("robbery involving only the use of intimidation is a felony involving the use of force or violence" under prior POWPO statute).
2. Evidence's Sufficiency
Defendant maintains that his class five felony POWPO conviction should be reduced to a class six felony because the evidence was insufficient to allow the jury to determine whether he used a deadly weapon in committing the prior felony menacing offense. We are not persuaded.
Whether the evidence was sufficient to support the jury's finding that defendant used a deadly weapon when he committed menacing is reviewed de novo. Dempsey, 117 P.3d at 807.
As discussed above, felony menacing is, by definition, a felony that involves using force and therefore triggers a POWPO conviction's enhancement when committed within the prescribed time frame. Because felony menacing is per se a felony that involves using force, the enhancement here did not depend on the jury finding that defendant actually used force or a deadly weapon in committing the prior felony menacing offense.
3. Jury Instructions
Defendant contends that the trial court committed reversible error by failing to provide written instructions to the jury stating that it had to unanimously and beyond a reasonable doubt find that his prior convietion was a felony involving the use of force or a deadly weapon to find him guilty of a class five felony under the POWPO statute. We discern no basis for reversal.
Where a defendant preserves objection to a trial court's failure to properly instruct the jury, harmless error review applies. Griego v. People, 19 P.3d 1 (Colo.2001).
Although the POWPO verdict form and written jury instructions here did not include burden of proof and detailed unanimity instructions, the jury was adequately informed concerning proof beyond a reasonable doubt and juror unanimity requirements. Defense counsel discussed proof beyond a reasonable *16doubt at length in his closing. Additionally, the jury was provided detailed written burden of proof and unanimity instructions earlier that same day when it deliberated on the burglary and theft charges. The trial court also provided oral instructions informing the jury that its verdiet must be unanimous and that the prosecution bore the burden of proving the charges beyond a reasonable doubt. Thus, we conclude that any error in the written jury instructions did not contribute to the verdict. See People v. Pahlavan, 83 P.3d 1138, 1142 (Colo.App.2003) (we presume jury understood and heeded court's instrue-tions).
Defendant also asserts that the special finding verdict form requiring the jury to determine whether "the previous conviction involve[d] the use of force or the use of a deadly weapon" "broadened the grounds for conviction by misstating the statutory element." The form omitted the term "felony" and referred to the previous "conviction." However, because felony menacing is, by definition, a felony, any error was harmless.
VI. Conclusion
Defendant's judgment of conviction is affirmed and the case is remanded to the trial court to correct the mittimus by merging the first degree burglary convictions.
Judge FURMAN concurs. Judge TAUBMAN specially concurs.
