As most of you know from previous threads I have had a Totally Custom Rock River Arms 1911, built from the ground up to my exact specs, parts and springs even. (not to mention the custom Bob Ford 1 serial number), Has blown up 3 times now. Once during a qualification that I was instructing. In demonstrating a double tap the second round blew the chamber out of the ejection port. The second time was during an NRA Law Enforcement Firearms Instructor Development Course. Again the second shot of the double tap went off like a twelve gauge. The entire barrel hood wound up in the next zip code. The third time, just a couple of months ago, was during a steel challenge match. I had hit 2 steel plates and when I fired at the third the gun made an unusual report. The bullet struck the steel plate and was heard by several other shooters. I stopped shooting and ejected the magazine, smoke poured forth. I looked at the barrel hood and there was a crack going down the entire length.
I have been firing weapons for over 40 years and have never had a gun blow up on me, that's including M-60's that the barrels were so hot they glowed and you could see the tracers whipping out of the molten barrel in all sorts of directions.
I am at a loss to explain why this occured (3 times? give me a break) but the point here is that any gun can fail and as mine did all 3 times was not just practice, it was high pressure competition, and as we all know, that's as close as most of you will ever get to the real thing, (God Willing).
All 3 times the gun was out of commision and useful only as a blunt force object.
At that point in a gunfight, without a backup, you have to learn to run at 1500fps in a wildly zig-zag pattern
