Glock Kabooms? Not what you think

[Arik]

I was on a different board where handgun reliability came up. Of course everyone jumped on the Glock 40sw Kabooms but one guy insists that the local department had 45 and 9mm Kabooms. Never heard of that one before. Tried googling and all I get is the 40sw results.

Guy says it was the next department over from his. Not saying it didn't happen but find it highly unlikely. Sounds like one of those things where you heard it from someone who heard it from his cousin's step father's in-law best friend!

Still though, I'm curious. Was there ever such a thing?

I've seen a few pistols of all makes go kaboom over the years.

By kabooms I'm talking primarily of case head separations which vent through the lower part of the pistol, primarily the mag well.

I'm sure that you know that the .40 Glocks have a lot of case head web area unsupported which combined with the pressure of the .40 cartridge led to most of the kabooms over the years - especially with brass on the 3rd trip through the reloader.

The 9mm's and .45's don't generally have the same problems. Most of the kabooms with those are more ammo related. The first thing I'd ask your buddy is whether the PD's in question are using reloads.

If they are, it is often hard telling how many times the case has cycled through the loader.

In the case of police agencies using Glocks, you can see how the problem gets transferred to the 'Glock.'

Another thing you might ask your buddy to find out - who paid to replace the pistols?

This, but I'll add that later production Glock 40's have better support. I've shot plenty of new ammo and my reloads through my G23 and have not once seen a case with the "Glock smile" on it. Most 40S&W pistols that were originally developed as 9mm's have some lack of case support. Also, 40S&W cases now have much better case web support than they did in the beginning. Basically, I don't view this as a problem unless you shoot reloads that contain compromised cases. If you reload and find a case that has a bulge at the web, simply toss it. Lee actually makes a die to remove these bulges. I'm pretty tight when it comes to money, but I can't figure out why some people think that getting rid of this clue that the case has been compromised is worth the risk.

I would bet this is the bases of 99 percent of LE kabooms. Cheap bean counters ordering manufactured ammo to save. Who know how many times that brass has been reloaded. David

I had a relative just Kaboom! his Glock 22, .40 S&W.

Moncarch PPU headstamp FMJ 180 grain. He'd fired probably 2500 rounds of the same stuff with nary a problem. Then, Kaboom! I saw the case; classic Glock head blowout.

Glocks also Kaboom! in .45 ACP and 10mm.

I don't like Glocks, anyway. My M&P has the correct grip angle, and its chamber is fully supported.

I've experienced kbs, and seen the aftermaths of many more. Majority were .40 and within a range of time. There were less .45s, and even less 9mms. Majority were Glocks, but there were others too. Like "brass to face", it is something created by a combination of variables and conditions, not something inherent in a make or model of gun, nor a particular ammo sku.

The "kaboom" was frequent enough with some combinations of variables that a couple of places had highly refined processes to deal with it.

Ok, so at least it is a possibility. There's so much shit floating around about Glocks, mostly from people with a bias. I've heard Glock mags melting to the frame in hot weather, which is why BP doesn't carry them! . So this .... especially the 9mm.... sounded like more of that

How do you feel about the Luger or the HK P7 grip angle?

I had an m&p kaboom with tula .40.
The gun was undamaged. Case blew out the back, similar to the casing shown in post 3 by bret, but it split.

I recall my Police Academy we fired Atlanta Arms lead round nose 9mm in our S&W 5906's. Didn't have any KB's, though.

Most of the guns ran really well, too. Maybe one or two bad apples if I recall.

My opinion of the gun was far higher at the end than it was at the beginning.
