I prefer the 10mm as well. I can do anything with it thatcan be accomplished with the "lesser" calibers.I do not like the .40 S&W because it has limitations. The .45 acp [I feel] is better and there are excellent [better]
rounds available to use. I really like The Golden Sabre 185 gr .45 acp +P for SD carry; they have great ballistics.
I do [also] carry a 1911 10mm and I've found The Double Tap 180 and 200 gr XTP/JHP's to have nice power and
accuracy - KA-BOOM.
