My duty sidearm is the Glock 19. The load is the Federal 124 grain +P HST. I actually like the 9mm and I shoot it well. I used to carry the Sig Sauer P220 in 45ACP. Good round as well, but I have to admit I like the higher round count of the 9mm. However that's just me. Most of the officers with my agency carry the Glock 21 in 45ACP.The caliber debate will never end. I decided to withdraw from that war many years ago.
