P - larger projectile than a 9 or 357 or 38. Many fine semi-autos made for it..
C - ammo can be hard to find worldwide. Recoil depending on size of pistol
I believe its .40 S&W or .45 ACP. Pros & Cons to both, trade off in ammunition capacity, recoil severity, etc....Comes down to personal preference. FBI is keen on the 40 S&W. Most 40s will have a larger capacity than 45s. Go to a range that rents guns, and see which you prefer. At this point, its about personal preference more so than effectiveness (they both are good defensive rounds).

40 cal ACP (not CAP) is the same as 40 cal. S&W. ACP refers to 'automatice cartridge pistol' wheras S&W refers to Smith and Wesson, who also make the 40 cal. cartridge....

A weapon that is chambered in 40 S&W
.40 S&W 156 dB
I have one. I understand that Colt made 1911's for about 9 months that used 40 S$W cartridges. Probably stopped because they were competitors with S&W. I have another Colt that shoots 40 S&W but I don't remember the Model number.
The ammunition is called .357 Sig. Most pistols in .357 Sig can shoot the .40 S&W when you drop in a .40 S&W barrel.
