ronccowboy Posted January 21, 2013 Share Posted January 21, 2013 this weekend i had my 6 yr old match 34 glock with a KKM drop in barrel blow up. top and bottom seperated about 2/3 way down the barrel. No dud, single shooting drill from a std mag. all factory ammo ( i don;t reload) and i have installed a smooth trigger. the barrel was 2 years old with around 1500 rounds fired thru it with no problem. Anyone know of a problem with these barrels? it blew the front up about 3 inches off the rail. and lost the guiderod and spring. so far i see nothing else impacted. no injuries got lucky.

JaeOne3345 Posted January 21, 2013 Share Posted January 21, 2013 How do you know it wasn't a bad factory round? Link to comment Share on other sites More sharing options...
JimmyZip Posted January 21, 2013 Share Posted January 21, 2013 How do you know it wasn't a bad factory round? He probably doesn't, but that wasn't his question was it? Did you by chance manage to save any part of the casing of the suspect round? Did it eject from the gun? I am not aware of any problems with KKM barrels. You might try a search, but I think if there were an issue we would know it far and wide here as a lot of us are using KKM barrels. Link to comment Share on other sites More sharing options...
Sarge Posted January 21, 2013 Share Posted January 21, 2013 sure sounds like an obstruction Link to comment Share on other sites More sharing options...
JaeOne3345 Posted January 22, 2013 Share Posted January 22, 2013 (edited) He probably doesn't, but that wasn't his question was it? That was not his question but it is a possible issue that has come up before, hasn't it? I am merely mentioning it because sometimes people get bad lots of ammo. Perhaps he can inspect the remaining portion of the ammo for any weird things such as bullet set back, etc? What is with the snide tone? We are all here to help each other. Many possibilities in a case like this. Might as well explore them all to help arrive at the answer. OP: Check the remaining lot (if you have any left) for any bullet set back. I personally have not ran into problems with a KKM barrel in my G34. Edited January 22, 2013 by JaeOne3345 Link to comment Share on other sites More sharing options...
hysupra Posted March 4, 2013 Share Posted March 4, 2013 Hi guys new member but I think JaeOne is probably right. KKM's quality is top notch so I dout its the barrel. I had a bad box of Hornady match 22-250 for a remington 700 I had. Fired about 5 rounds and then KABOOM. It took a 5 pound leather hammer and 3 really big dudes to get the bolt to release. Blah blah blah... Anyways I called Hornady they told me to send them the 2 boxes of ammo I had baught and the rifle. They found that the brass what not treated properly (Im missing the technical term there) and they sent my gun to remington and fixed it up for me. So long story short, contact the company and you might get a new barrel. Link to comment Share on other sites More sharing options...
DougCarden Posted March 5, 2013 Share Posted March 5, 2013 Call KKM. They will want to look at the barrel. Start there. Glad you are ok.... DougC Link to comment Share on other sites More sharing options...

ronccowboy Posted March 8, 2013 Author Share Posted March 8, 2013 followup. i know it was not an obstruction. I was doing specific draw and shoot 1 time at IDPA target practice a la steve anderson drills. I sent the barrell back to KKM. After ripping the barrel apart, they sent me a 1 line letter saying it had to be an obstruction and majic markered the barrel right next to the chamber and suggested that was where the obstruction was. I'm no gunsmith, but as a materials engineer the barrell failed about 1 1/2 inch futher down the barrel and the split continued approximately 2" beyond that. I have had two of our city's experienced gunsmiths look it over and both agree it was barrel failure. So much for KKM. By the same token, i would be remiss if i did not note the Glock response. I sent the gun parts back to Glock for review and estimate for what it would cost me to fix. i wanted to make sure the gun was safe beyond a visual check. i explain that the after market barrel had failed and included pictures of the barrel and gun before i disassembled it. They replace the barrel, pushrod, springs, put it in a glock box and added a mag. sent it back to me with a manifest that said - gun returned to factory specs, ok to use, no charge. If you don't think that kind of service makes me proud to shoot a Glock.. Link to comment Share on other sites More sharing options...

bountyhunter Posted March 8, 2013 Share Posted March 8, 2013 (edited) Call the ammo manufacturer IMMEDIATELY. same thing happened to somebody who shoots in my league. Probably very likley to be the ammo. They might take responsibility. Edited March 8, 2013 by bountyhunter Link to comment Share on other sites More sharing options...
