Not really off-topic, for this has gotten "out there" a bit . . .
The Georgia Highway Patrol recently transitioned out of the .45GAP full-size Glocks to the Glock Gen4 Model 17 (9mm), and also picked up the Glock 42, at first for a BUG. Soon they went Model 43 and offered some sweet deals to troopers on the Model 42. They guy I talked to loved both.
WHY 9MM? He said because there are some great rounds now on the market. The .45 GAP didn't sit well with shooters with smaller hands, so qualifying scores shot up with the new M17 G4s.
PLUS, in gunfights the .45GAP killed the perps eventually, but didn't put 'em down well. OTOH, the 9mm rounds today hit pretty hard, and t he rattle around inside the body, inflicting faster incapacitation, according to the trooper. The force is very happy with the M17
He also loves his G42, and being off duty when we talked, he let me handle it. Nice. He's buying one for his wife.
BTW, the new tactics call for more initial rounds at a perp. Swarm them with lots of rounds and keep shooting on a bad risk. The 9mm carries a lot more rounds.
WHAT I'M PLANNING - Before all this junk happened I'd been looking for a M19 Gen4. I never cared for the M23 .40S&W but the 9mm would be a nice thing, I believe. I'll probably still pocket carry my trusty Model 37 snubbie though, but increased firepower would probably come in very handing if stuff hits the fan one day.
My wife has also been thinking about a compact auto. I never thought she'd think about swapping her vintage Model 37, 3 inch barrel version for a pocket pistol. Additional rounds in this new age is a good thing.
