I have two 9mm 1911's; a Colt Commander and a Kimber TacPro. The Kimber was bought for carryin', since it's got the alloy frame. I bought both simply because they were there; it's hard to find many 1911 choices in 9mm if you only buy used and only buy local.
Lately, I've been looking at maybe breaking down and ordering a Springer alloy frame 1911 in 9mm. All things being equal, I would prefer a Springfield over a Kimber or S&W or Colt, since the Springer's don't have any extra 'non-JMB-approved' firing pin safety thingee. My local gunsmith really likes the S&W, but I don't think that they offer a 9mm version.
