I have a couple cheap Uncle Mike's for the USP, and they leave quite a bit to be desired.  I think I will start using the 1911 for CCW as well, and would like to improve my holster situation.  All advice is welcome.

I have a DeSantis Cozy Partner.  Nice holster that solidly holds a full size 1911 in place without digging into me.

I bought it at Hoffmans on the Berlin Turn Pike.  It costed about $40.00.  can't beat that cost for a high quality leather holster.

Great quality, reasonable cost.  The waiting period can run a couple of months though.

I have an on-the-belt holster made by Sam Andrews for my USP and it works great so long as I can cover the gun with something like a light jacket. I prefer to carry strongside, on the belt with all my handguns, and do not want any straps, flaps or buckles in the way of a concealed draw. This requires a well designed holster. Sig230 and others have a good point when they recommend a really good belt as the first item to purchase when considering a concealed carry system. Not that you would, but you can do better with a flimsy, "chicken hide" holster on a well designed and built belt than vice versa. That said, you can't make the USP into something it isn't. A large, blocky handgun is going to be more of a challenge to conceal than a smaller, thinner weapon, and, once the "new" wears off, carrying a gun ALL the time can get really old. My favorite holster maker is "Wild Bill" Bowden. Excellent quality at reasonable prices...however...like many other makers, he usually cannot deliver without a wait.
