I only deal with Glocks in 9mm.
Glock added a coil to the mag spring and a new follower. Things supposedly improved. Not sure if the fix is 100% though.
Glocks were designed and built around the 9mm.
I only deal with Glocks in 9mm.
mine just blew, 9mm reloads all under the max pressure. The base of the case blew out the side breaking of a piece of poly frame and cracking more. Most ofthe shraplnal went out the left side and into my hand. I have fired around 500rounds with this Gen 4 and this was the first problem, still hurt like hell thought ok. Local Dealer won't help because warrenty was void as soon as I used read ammo. I agree that the chamber should be desisned better to support the bass.
If Glock redesigned the barrel and admitted a design flaw,and all the .40 cal they have out there, imagine how much the cost would be for that move....JJ
I'm having a hard time understanding this. If the reloads are all under the specified pressure, or at least supposed to be, is it likely that reloading errors are to blame, or is it more likely caused by something else. I've got more than 3000 rounds on my G17 and really enjoy it, but I've never gotten around to trying a reload in it.
the case expands and stretches during firing (i did know this) and when it elongates the case wall thins out (i would have known this, it stands to reason the brass must come from somewhere).
also the case rim is weakened by the extraction process (even NEW FACTORY ammo is only designed to be cycled 2 TIMES)
so you have a weakened rim and a thinner walled case and now you are loading everything to the max.... and the case is NOT supported correctly due to the design of the barrel.
now we might have one more factor.... the bullet is set in the brass at a certain depth, just loading it into the camber via the slide can set it back into the brass even deeper, creating even greater pressures , and a weakened case.....
in a design where the case is fully supported, you get a split case... in a glock, you get a catastrophic failure.
its no secret that i am not a glockophile, and havent been since the days i was UNinstalling the new york triggers in my own shop. but this condition has been cataloged and photographed and blogged and reported on for almost 2 decades.... glocks blow up , ALOT
1) The unsupported chamber myth--that ended late in Gen II. Gen III pistols have a pretty much typical chamber for modern pistols.
2) I have a G22, G23, G27, and G35. I shoot USPSA and IDPA with those guns. I have literally tens of thousands of rounds in matches and in practice with nary a hitch, glitch, or "kaboom". 40 is a high pressure cartridge, plain and simple. GLOCK is no more prone to issues than other designs. In fact I have personally seen more 1911s blow up than I have GLOCKs. It's 4:1 so far. 1 G27 vs 1 Springfield, 2 Kimbers, and a Sig 1911. A shooter was injured in only one incident--the Sig 1911 had an apparent overcharge and literally blew in half. The shooter took shrapnel to his hands, forearms and face. It was at a match, so he had eyewear on and was not more than superficially injured.
9mm Glock Ka-booms are rare enough on their own pre Gen 3. Gen 3 9mm Glock ka-booms even rarer still. Gen4 9mm Glock ka-booom, not likely going to be the gun.
Gotta' go with Dan on this one. The unsupproted chamber was more of a .40 / .45 issue and Glock changed the chambers a while back improving case support. Blaming the chamber for a 9mm ka-boom just doesn't fly IMHO.
Are you using a powder alarm?
