Segregate 1911 and Glock fired Brass?

[M&PUSER]

I've often read that Glock chambers are overly enlarged to accommodate all types of manufacturers cartridges.

Would it be a prudent move to deliberately set aside brass for firing exclusively in my Kimber 1911 45 ACP and brass I"ll be using in a Glock 30S I'm thinking about purchasing?

What's the true story?

No. Not for .45.
If you pick up brass from a USPSA match, you may get some .45 brass that was shot in loose chambered race guns. Usually it sizes OK, but some of it is past using.
.40 S&W brass is a different story. The head can be expanded in various guns past the point that a regular die will restore it to spec.

Can this brass be salvaged?
I am assuming this is a problem with Glocks.

Usually. Need a push-through die or a roll sizer.

Lee Factory Carbide Crimp Die solves this problem for about $12. I have one for each handgun caliber I reload, 38/357 use the same die just like 10 MM/40 S&W.

EDIT: I use the Lee FCCD with RCBS reloading dies. The RCBS sizer die is carbide so I don't have to lube cases. All my 40 S&W and 9 MM brass came out of Glocks fired at a police range or indoor range.

I would just like to point out that you have to have the lee FCD and another "kit" to make it push thru. I have the push thru "kit" and use it on my 45acp, 40sw and 9mm lee FCD dies (you only need one kit for all). Older glocks (g1 &g2) got the glock bulge not so much the G3 and G4's. I have a Glock 23-2 and it has the bulge. since i reload it put a lone wolfe barrel on it to shoot lead and not have to worry about how many times i resize the brass with the push thru die.

It's unnecessary. Glock .45s are fine on brass.

I have Glock .40s and use a push-through die, but I wouldn't if I was using .45. Besides, .45 is about half the pressure!

[Kilibreaux]

The .45 ACP maximum average pressure is just 21K CUP. This is rather low by industry standards and suggests that you are perfectly safe to use once-fired .45 ACP brass in ANY pistol.
Granted Glocks tend to produce a "bulge" where the case web lies over the feed ramp scallop, and truly HIGH pressure cartridges such as the .40 S&W and 10mm will often cause a prominent bulge, this is NOT common with a standard pressure .45 ACP.
Bear in mind the .45 ACP round was developed to reliably function with the 1911 platform way back in 1905. It is NOT a "high pressure" cartridge outside of any street mis-perception. The U.S. Army always "derates" its equipment, so the mil-spec .45 ACP loading is a mere 350 lb-ft of kinetic energy - pretty decent delivered energy based upon the original specifications, but the point is, a standard ACP loading simply will not "over stress" any modern .45 ACP brass.

[Granddad]

As others said, unnecessary, especially for your 45s. Once you deprime/size the brass it will all largely be the same.

[TAROMAN]

Years ago when I had a GLOCK 30 in addition to several .45 1911s, I bought the Lee "Bulge Buster".
Totally unnecessary in .45.

At factory pressures, not an issue IMO. I shoot range pickups all the time, even in my barsto match bbl 1911. The low pressures of the 45acp is pretty easy on brass.

Yes, they are "slightly" larger, but not so to accommodate different brands--which should be meeting SAMI specs. They are enlarged to ensure feeding.

I have bags of range brass in several calibers, much I know was fired in Glocks, and I've yet to see any bulging different from any other firearm brand.

Years ago--keep in mind that event years ago remain as posted today on the internet--early Glocks in .40 had a support problem, but that issue was resolved long ago. I've reloaded .40s for my son, full length resized only, never yet used a FCD or push-thru, and all worked fine.

And I never separate brass.
