I don’t think that’s supposed to happen.
I was chatting with the owner of my local Ye Olde Gunshoppe this afternoon when a fellow walked in from the range and up to the counter, carrying a Smith & Wesson 638 Bodyguard… or at least most of its pieces.
He’d been shooting away with some PMC factory ammo when the frame let go at the barrel threads, launching the barrel downrange and allowing the cylinder/yoke assembly to fall out the front of the broken frame.
No injuries, fortunately, and everything BUT the frame was completely intact. The cylinder and barrel (which was recovered from downrange) were in perfect condition, with no bulges or signs of obstruction. Fired cases were unremarkable. The shooter reported that the gun was only a year old and had seen some use but no abuse; no handloads and no +P ammo.
My best guess is that some kind of tiny stress riser or fracture started when the barrel was first torqued in, gradually growing until the catastrophic failure.
This was only the second serious failure I’ve seen first-hand; the first was a fellow who locked up his Remington 700 with a way-too-hot handload and broke the bolt handle off trying to beat the action open. While that case was obvious operator error, this one spooked me a bit. First, the shooter seemed to be doing everything right when his gun suddenly came apart in his hands… and second, his revolver was nearly identical to the one riding in my pocket as I type this.
