Something you will also need to consider is which size 1911 you can conceal. I have both a standard 5" barreled one and a 3" barreled one. Both can be concealed, but have to be carried differently based on your body type.
I have no trouble concealing a Third Generation Taurus Millenium Pro PT145. It holds 10+1. And, I got it for a steal at $350 + Tax new!
I really like it as it fits my big hand with stubby fingers and so far have not had any problems.
I have been shopping for a .45acp CC hangun. I plan to pick up a Taurus Millenium Pro PT145 with my next pay check. I will let you know what I think after I put a thousand rounds thru it.
