ABSTRACT:
An automatic handgun has a support member fixed to the end of the barrel and engageable with the slide when the slide moves forward. The mating surfaces of the support member and the slide have clutch surfaces machined into them so the two surfaces lock together snugly, thereby holding the barrel and slide together accurately. A guide rod may also be fixed to the support member to assist in holding the proper relationship when the slide is moved rearwardly.
