What caused this to happen?

[Bruce McAskill]

IF you read the post he said he found parts of the cylinder on the ground....

I think he stated he had found revolver parts there before in the past and not when he found the case.

Do you think a 1911 .45 extractor would "catch" and hold on a .40 case like you described?

I just tried with my Auto Ord and the .40 fit and fed perfectly out of the mag. When I released the slide the cartridge was launched out of the barrel. Then I carefully tucked it in under the extractor and it stayed. It might work, it would when held vertically, I still wonder if that was a Glock that did that? Mine is a 22 so I can't try it. I'd need a 21...

Here are some pictures of the revolver cylinder. I'm not sure of the brand - maybe someone will recognize it? I found this on the ground several years ago very close to where I found the split .40 case. There are several revolvers out there that can fire .45ACP, but don't think it would be easy to fire a .40 S&W in one of them. Jim, does the Glock leave bright marks on either side of the firing pin dent? I have some .45 cases that I picked up near the .40 - I could take pictures. - Bob

does the Glock leave bright marks on either side of the firing pin dent?

It leaves an oblong firing pin mark...vertical firing pin mark.

These .45's must be the same deal. I think my "bright" areas are from contact on the raised metal at the narrow ends of the oblong mark. Thanks for showing me something else I never knew before! - Bob

I have seen that bulging before. Happened when i reloaded some 44 mag rounds, but didn't have a box to put the reloaded cartridges in, so I used a 45 colt box. Went out shooting months later with the 45 and couldn't hit anything, pulled bulged and split cases from the cylinder and realized what I had done.

Hopefully or should I say obviously your rounds weren't hot for the 44 Mag shooting them out of a 45 Colt now that would have been fun, I know when I shot factories out of my 44 Mag Super Redhawk it was a very lively beast in the hand indeed.

Looks like Glock marks to me...

your rounds weren't hot for the 44 Mag

Wouldn't matter, there's enough space to allow most of the pressure to just blow by. Nothing to contain it.

Were any beer cans found at the scene? Stray digits?

True enough BAR but what I was thinking of the .429" (.451" for the 45 Colt) pill not fully concentric with the forcing cone and getting a bit skewed but I guess the weapon fired as intended with no harm done to anything save for a bit more blast exiting out near the cylinder face and forcing cone.
