In January Philadelphia (PA) Police, my department, will switch to 147 grain Federal HST 9mm ammo. We used to issue 115 grain Federal Classic (9BP). The 147 grain HST did very well in testing. One factor that makes 147 grain a good choice, IMHO, is the fact that it gets cold here in Philly so the bad guys are dressed in several layers of bulky clothes. The heavier bullet will penertrate better than a lighter round. And HST's tend to expand very well.
We also have the option of buying and using a Glock .40 or .45! I choose the Glock 21SF in good old .45 ACP!!!!!! We are issued 230 grain HST .45 and 165 grain HST in the .40's. All very good rounds!
one nation, UNDER GOD, with liberty and justice for all.
Glock 21SF (Duty), Glock 30SF, Glock 19
Glock 27, Ruger LCR, J-frame
Plenty of room for more....
