Very controvercial. 9mm vs .40 S&W.

A crimp die is used to crimp the case mouth. The bulges happen at the back of the case. These can be corrected by pushing through a die of some sort. However, the brass will never be quite the same. Glocked-up brass can be identified by rectangular primer impacts.

Fine print:

Glock Cases: We do not recommend "fixing" cases fired in pistols with unsupported chambers, because there is no way to make them safe once they have bulged. The case wall is thinned where it bulges, and resizing the outside of the case back down to the correct diameter does not restore the case back to its original thickness. If this case is fired in a pistol with an unsupported chamber again, and this thinned section of brass happens to line up with the unsupported part of the chamber, there is a high probability that the case will rupture.

9mm is a better first calibre if you plan to reload or shoot reloads.

Yes, that is what a crimp die does. However, off the top of my head, that is what I think Lee calls the die in question. It looks like a seating die and removes the Glock bulge at the base of the case. I have run hundreds of rounds so squeezed through both my M&P and my Glock.
 
The plus side of reloading .45acp is that it's really easy and the case last a long time. The downside is bullets cost more and you spend a lot of time on your knees looking for cases.

Since the Gen 3 came out the Glocks support the case as well as any other pistol. The Gen 1 & 2 Glocks had the unsupported area at the 6 oclock position on the case. Oversize chambers is the major problem now. My Dillon dies seem to manage the brass well enough.

Have you any evidence of the high lighted statement or are you repeating internet lore?

Bob, I believe that is a quote from the Lee "Bulge Buster" link: ht tp://leeprecision.com/bulge-buster-kit.html

If it is it is pure marketing hype. I have never heard of a resized case letting go or it being a problem. I have shot lots of resized Glock brass with no hint of a problem. That said all my pistols suport the head of the case. I guess if you shoot a Gen 1 or 2 Glock it could be a problem.
