Jeff, I am glad you posted that video. I love 1911s but I am not a fan of 3" 1911s for this reason. The evidence is out there, all over the 1911 forums. Their is a reason top 1911 smiths do not work on the 3" guns that much, or at all. They are not reliable in my opinion, and many other people agree. The fact that this video was posted with Pincus (a well known trainer) backing it should back the information even more.
I know people out there will disagree, say things like 'my gun has never had a problem.' But to properly test a carry gun, I think it should be put through a 8hr class or the equivalent. Every gun I have has been thorouly tested at the range before it was carried. I have a 3'' Kimber .45, it sucks for a carry gun. It does not cycle most hollow point ammo and even chokes on ball often. I would never trust a 3" 1911.
Just my two cents,
George
