Opinion by
Wright, J.,David N. Curry has appealed from an order of Court of Common Pleas No. 5 of Philadelphia County, entered November 4, 1960, dismissing his petition for a writ of habeas corpus. We have reviewed the original trial record, which may relevantly be considered and may not be collaterally impeached. See Commonwealth ex rel. Chaney v. Cavell, 185 Pa. Superior Ct. 82, 138 A. 2d 180. The pertinent facts are as follows:
Appellant and his wife had been separated for some time, the wife living at the home of her parents. It was appellant’s custom to visit his wife at intervals in order to see their child. On one of these occasions he took a revolver belonging to his father-in-law. At 7:30 A.M. on December 20, 1957, armed with this revolver, appellant went to the father-in-law’s house. He gained entrance through a cellar window, and ascended to the third floor where he found his wife asleep in bed. He fired one shot into her head. Appellant remained in the house for approximately thirty minutes and then “decided to leave and let someone come and find her”. After stopping at a bar for a drink, he went to his brother’s residence, where he was eventually apprehended by police officers at eight o’clock that evening. Meanwhile, the wife lay in a pool of blood until her father came home from work at 2:30 P.M. She was removed to a hospital where she remained in a coma until sometime in February, 1958. She was not released from the hospital until June, 1958. At the time of the trial, October 20, 1958, she was still badly crippled, and her speech was impaired.
*483Following Ms arrest, appellant was taken to City Hall where he was questioned and made a statement admitting his guilt. He was then taken to a police station and detained for a hearing the next morning. At March Sessions, 1958, the grand jury returned three indictments as follows: Bill No. 75 charged assault and battery, aggravated assault and battery, and assault and battery with intent to murder; Bill No. 76 charged commission of a crime of violence while armed with a firearm; Bill No. 78 charged carrying a concealed deadly weapon and unlawfully carrying a firearm without a license. Appellant was represented by counsel. Jury trial was waived. A demurrer was sustained as to Bill No. 78. The trial judge found appellant guilty on Bills Nos. 75 and 76. No post-conviction motions were filed. On Bill No. 75 appellant was sentenced to serve a term of three to six years. On Bill No. 76 he was sentenced to serve a consecutive term of one to three years.
In his brief appellant advances many of the usual trite contentions. He variously avers that he was arrested and held “without witness to the fact that he committed a crime”; that he was not allowed to see or communicate with an attorney at the time of his arrest; that there was no proper preliminary hearing; that it was unlawful to take Mm to police headquarters for questioning; that his confession was coerced; that he was convicted on perjured testimony, and that the evidence was insufficient to sustain his conviction. We find no merit whatever in any of these contentions.
In Commonwealth ex rel. Lockhart v. Myers, 193 Pa. Superior Ct. 531, 165 A. 2d 400, we discussed the subject of habeas corpus at considerable length. In brief, relief from alleged trial errors may not be obtained by habeas corpus, as the writ is not a substitute for a new trial or an appeal. Defects and irregularities in the information, warrant and proceedings before *484the magistrate are cured by pleading to the indictment and going to trial. Cf. Commonwealth ex rel. Dandy v. Banmiller, 397 Pa. 312, 155 A. 2d 197. The fact that appellant was in custody without counsel did not invalidate his confession: Commonwealth v. Agoston, 364 Pa. 464, 72 A. 2d 575. An attack upon the evidence adduced at the trial may not be a subject of habeas corpus, either on the ground that it was perjured: Commonwealth ex rel. Whalen v. Banmiller, 193 Pa. Superior Ct. 554, 165 A. 2d 421, or generally insufficient: Commonwealth ex rel. Butler v. Banmiller, 190 Pa. Superior Ct. 474, 154 A. 2d 330.
The record of the trial discloses that the proof of appellant’s guilt was overwhelming. His wife, father-in-law, and one of the investigating police officers testified against him. In addition, the statement given shortly after his arrest was received in evidence. Appellant did not contend that he was in any way mistreated or imposed upon by the police officers, nor did he challenge the voluntary character of his confession. In that document, appellant described his relations with his wife and her family, and vividly detailed the events preceding, during and following the shooting. As the sole defense witness, he admitted the truth of much of the confession, denying only the events surrounding the actual offense. He asserted that he had been drinking, that he suffered from blackout spells, passed out, and “would be unconscious and, naturally, I did not know what I was doing if I would be unconscious”. These feeble repudiations did not impress the trial judge, and they certainly furnish no basis for relief by habeas corpus. The writ may not be used to reexamine the question of the voluntariness of a confession when that issue has been passed upon at the trial, and the record shows that there was no fundamental unfairness amounting to a denial of due process: Commonwealth ex rel. Norman v. Banmiller, 395 Pa. 232, 149 A. 2d 881.
*485We would conclude at this point except for an important question, not advanced by appellant, which has been raised by Judge Waters in his opinion written pursuant to our Buie 43. It concerns Bill No. 76, charging that appellant “unlawfully and feloniously did then and there commit a certain crime of violence, to wit, the crime of aggravated assault and battery with intent to kill, when and while armed with a firearm, to wit, a revolver”. This charge is based upon paragraph (b) of Section 628 of The Penal Code1 which paragraph reads as follows: “If any person shall commit or attempt to commit a crime of violence when armed with a firearm contrary to the provisions of this section, he may, in addition to the punishment provided for the crime, be punished also as provided by this section”. It is the position of Judge Waters that this paragraph does not define a separate crime, and that appellant will therefore be required to serve a sentence which is in fact illegal. As stated in the opinion below : “In our opinion this subsection simply means that the crime of unlawfully carrying a concealed firearm without a license, that is, a violation of the Uniform Firearms Act, does not merge with a crime of violence referred to. The act did not create such a crime as ‘commission of a crime of violence while armed with a firearm’. In our opinion there is no such crime”. Our study of this question leads us to the same conclusion.
The Commonwealth has devoted the major portion of its commendable brief to this issue. It is of course undisputed that a penal statute must be strictly construed. See Commonwealth v. Glover, 397 Pa. 543, 156 A. 2d 114. Conceding that “before an individual may be convicted of commission of a crime of violence while armed with a firearm, there must be proof that he vio*486lated some other provision of the Uniform Firearms Act”, the Commonwealth attempts to demonstrate that appellant actually violated both paragraph (d) and paragraph (e) of the section.2 This argument begs the question here under consideration since it assumes that paragraph (b) does create a separate offense. It should be noted in this connection that, although appellant testified in direct examination as to Ms prior criminal record, he was not indicted under paragraph (d) and, as previously indicated, a demurrer was sustained as to the indictment under paragraph (e) and there was no appeal. We agree with the court below that paragraph (b) of Section 628 was intended to prevent the lesser crimes created by subsequent paragraphs from merging into the more serious “crimes of violence” as defined in paragraph (a). Paragraph (b) merely authorizes punishment, in addition to that provided for the crime of violence itself, “also as provided by this section”. The language is permissive in nature as contrasted with the mandatory and prohibitory language in paragraphs (d) and (e) and other paragraphs thereafter. In brief, paragraph (b) contains no indication of a legislative purpose to define a criminal act.
Our attention has been called to only one appellate case wherein “a crime of violence wMle armed with a firearm” was separately charged. See Commonwealth v. Tracey, 130 Pa. Superior Ct. 15, 196 A. 549. However, the question of the independent existence of such *487a crime was not therein raised or considered.3 It is of course proper to sentence, not only for a crime of violence as defined in paragraph (a), but also for a separate offense created by one of the later paragraphs of Section 628. Cf. Commonwealth ex rel. Monaghan v. Burke, 169 Pa. Superior Ct. 256, 82 A. 2d 337. It is our view, however, that additional and further punishment is not warranted by charging an offense under paragraph (b), which was not intended to create a separate crime.
The order of the court below is affirmed as to Bill No. 75 March Sessions, 1958. The sentence imposed on Bill No. 76 March Sessions, 1958 is vacated.
Act of June 24, 1939, P. L. 872, 18 P.S. 4628.
“(d) No person who has been convicted in this Commonwealth or elsewhere of a crime of violence shall own a firearm, or have one in his possession or under his control.
“(e) No person shall carry a firearm in any vehicle or concealed on or about his person, except in his place of abode or fixed place of business, without a license therefor as hereinafter provided”.
Judge Waters also mentions Commonwealth v. Chrostowski, 112 Pa. Superior Ct. 466, 171 A. 901. The opinion in that case simply refers to “violation of the Uniform Firearms Act”,
