Okay children,
one more time. A KB to count cannot be caused by a reload, in any weapon.
A KB to count against any Mark must be by factory Ammunition and non +P. There are no +P loads in 40.
I know of no KB in a 9mm Glock, 357SIG, or 45Gap.
Most of the KB's reported by agencies have been in 40 and to a lessor extent 45acp.
The KB I witnessed was in 45acp, in a Glock 21. Factory ammo, and the guy shooting it was a friend of mine and did not shoot anything but factory FMJ 230gr. IIRC he also shot some of Winchesters old range ammo SWC 185 FMJ too. This was about 11 years ago.
Some engineer friends of ours sent the barrel to a metallurgist. The results were inconclusive. I do not have a copy of the report.
The conclusion we came to was that the 40S&W barrels were basically over bored 9 blanks (yea I know, I simplified it) and the 45acp was a over bored 10mm blank.
Now about the Tennifer process. The conclusion is/was that on occasion QC would let a barrel out that was either to soft or to brittle, and because of the over bored barrels didn't have the amount of steel necessary to contain the cartridge. That is why it was not systemic to all 40 or 45 models. Just rare occasion. (Not a joke either, but a couple of the engineers were in fact rocket scientists working with NASA at Cape Canaveral. That area is where I am from, it is home.)
In the other calibers there seemed to be enough metal in the area's required to handle the occasional QC slip up.
That was the conclusion.
The only problem with unsupported shell is primarily for reloaders. Not fresh ammo shooters. (the wear factor on the unsupported portion of the case.)
It is not the fact that some Glocks have been known to fire out of battery. Many weapons have had a problem here without KB's. Glock too.
There were other problems, like the type 3 Jam on the Glock 19. And of course the problem with the E series frames rails. The type 3 seems to be solved, and most of the E frames are either not shot much, or traded out by Glock. And their original non recall recall back in the late 80's early 90's. (the problem, which they finally redesigned and exchanged 5 or more parts IIRC for, was a potential slam fire.)
A friend of mine had his E series 23 shear both rear rails. But understand that weapon had about 27,000 rounds through it. It wa, at the time, his primary CCW. He has since purchased a second 23. He has had the whole Glock family in 40 for about 5+ years. Not counting the rest of his collection.
My point is some Glock 40's or 45acp's may still KB. But it will not be many.
To those who drink Glock Kool Aide, Glock had a problem. Unfortunately Glock isn't a very open or communicative company. So we don't know whether they have solved the problem or not.
And no, no other make I can think of has ever had these kind of problems with factory ammo. Not impossible, but not an issue.
With Glock IT WAS AN ISSUE. But a small one. That is why several Agencies changed their Glocks in for other brands or models.
Now I haven't seen a 1911 KB with factory ammo. I am sure it may have happened, but I haven't seen it. Now it is true I am a beginner in this shooting game. Only been shooting for about 50 years, competing for only about 40 years. Started with NRA JR program in the 50's. Still compete today USPSA Steel Challenge & Pin Match's, and IDPA. Also a few other run what you 'brung' and special night match's and such.
Maybe when I get some decent experience I can speak with knowledge like a lot of the really experienced Pro and Anti Glock folks here.
Right now I still have 3 Glocks, all in 9mm, and think they are good guns. For the record my CCW these days is either a Colt Government Gunsite Pistol, or my Browning Hipower. But I am shooting the Steel Challenge these days with a Glock 34.
That's the facts, JACK.
Go figure.
Fred
