I've had 9mm 1911s of one kind or another since the '70s; Colt, Kimber, STI, Springfield, Dan Wesson, etc. Had more than one of most of these.
I've come to much prefer guns with the integrally ramped barrels, as opposed to the traditional Colt type unramped barrels, for any of the 9mm, 10mm, 38 Super, i.e., higher pressure cartridges. This, for superior case head support, and feed reliability with any appropriate bullet weight, profile, velocity level, etc.
PS, Like rbernie, I prefer the Metal Form Springfield "front ramp" type 9mm magazines. For years, these have been my favorite in any manufactuer's 9mm 1911 pistols. Should I need more 9mm 1911 type magazines, this is the type I would still purchase. There is something to that front ramp design. Wish I'd thought of it, or at last had it available years ago when I was struggling to get my Colts, with unramped barrels, to be reliable...
PPS, the full size Kimber stainless 9mms I've had functioned flawlessly from Day 1 with any appropriate ammunition. I would think that similar guns might be found for 1K or less new or used. The bull barrel STI Trojan I had was also excellent all around, but might be a little more $. The Dan Wessons are a cut above most production 1911s, but are higher $ still. My one Springfield production model, a Loaded Target Model, was problematical, but mine may have just been a late Friday afternoon gun. Some of the Springfields can still be had for less than 1K, so I'd still consider one, were I in the market.
