Treize,
Attached is the link for the Galco website, i found the make of my holster for my Kimber 1911, It is the Concealable. Ive had this thing for years, its not cheap, but its not that expensive either. I have mine on a Galco belt, the holster will run you about 109.99USD, and the belt another 50.00 to 65.00USD (thats in our shop, prices vary). I use the Galco belt because it matches up with the holster perfectly, and the holster does not have that "floppy, loose" feeling. The forward cantilever of the holster makes for a natural feel when pulling it, as it is the natural motion of pulling the gun and bringing it up and forward.
There is a bunch available for your Colt. Good luck. Again IMO, the Kydex and nylon holsters arent great for a 1911. With that said i do have a kydex for a couple of my other cc guns ( Glock, HK and Sigs) but not for my 1911. And truthfully, my Kimber is my primary cc gun. Hope this helps.
