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..
