22h2,
Both my 9mm 1911's feed with no problems. Only one has given me extraction problems, which has nothing to do with bullet weight and OAL.
It seems to me, with the rising cost of ammo, it's time for someone to offer a good quality 9mm 1911 at a reasonable price. I had read on the 1911 Forum Rock Island Armory was going to offer such a pistol this summer, but it's only a rumor. I think a $400-$500, reliable 9mm/1911 would sell very well.
