There's a small portion of the case that isn't well supported in the 1911A1, but it's at the strongest part of the case, where it meets the base.

If you really load up with a fast burning powder and you use often-reloaded cases, you'll find a bulge at the base of your shells to match the side of the receiver.

But I have never had one blow there. Plenty of cracked case mouths when I used a hull once too often . . .

I had heard all the reports (no pun intended) of Glock "kabooms" myself, so when I was looking for a DA pistol I went with the Sig instead. Just comparing the two, I thought the fit and finish on the Glock were inferior. That of course doesn't necessarily mean the working parts are bad, but it indicates to me a lack of attention to detail that might carry over into design and/or manufacture.

I think you have it right. Glock pretty much says, “you’re on your own” if you do re-loading.

I have a Glock 23 (40 S&W, compact frame), and I’ve never had a problem with it.
