EAA made a very good 1911 in 10mm from what I understand, Dan Wesson makes a few, the Pointman-7 and the Razorback-10 are the more popular models, the S&W 10xx series were built like tanks and will last you for quite a bit, Springfield made the Omega but they're hard to find parts for and from what I understand they're prone to small parts breaking easily. If you want an oddball 10mm you may want to look into what was known as the MEGAstar, those things were behemoths. As far as my two cents goes I just finished up shooting some Federal 10mm out of my RZ-10 and boy does that gun make me look good at the range.
