What does LCP and ACP mean?
ACP: Automatic Colt Pistol
L
LCP is I believe Ruger’s acronym for “Lightweight Compact Pistol” and ACP harks back to the original Colt which when adopted by the Army became the “Automatic Colt Pistol” - and with the military’s love of all things with an acronym, it became ACP... ;-)
You have a lot of options. I personally like the Kel-Tec P-11. I have also carried the Glock 27. The key is finding something that you can conceal easily and shoot accurately and reliably. Whatever weapon you choose make sure to know what load it likes the best and practice with that load. I like at least a 9mm load.
