I've found the velocity you get out of a short bbl 10mm 180 gr bullet isn't any better than the 185 +p DPX Cor Bon 45 out of a 3" 1911. I prefer the 1911 trigger and all season IWB carry. The 41 with 250gr Federal Cast Core stomps all over the 10mm, and it is a favorite of some Denali park rangers. If I want to pocket a gun, I have to move down to the 16oz PM40, but even with the nice Kahr trigger, some practice is required. If I had to pick one of the three, I'd keep the sub compact 45 for all around use. A low pressure load with the right powder has minimal blast and flash. With high pressure and magnum cases, a short tube negates a lot of potential power, but makes a great show at night.
