Been weaning myself off the internet so I haven't been on this forum for I guess a year, just quit my last job (Security) and on an impulse decided to check out things. Well, not much has changed but I love playing games so I'll weigh in.
The SW city I worked in is nasty, especially at night. I always worked graveyard and am a level 3 so I got to see things the way they are, and things are worse than I thought. They're going to get much worse due to the new D's that took over including the Gov. Also been getting many (100's) of migrants that ICE is letting go and the Catholic Charities are bussing here. Even without the migrants things are just crazy.
When I started working I had usually 3 revolvers on me, my 65-1, 640-3 and M&P 340. Revolvers are good because there's nothing to remember except aim and squeeze. The problem was that though there were many single perp incidents most were crews, usually 4 bangers to a car, many times multiple cars. I needed better firepower and probably should have bought a G-17 but went with a M9A3. I could have bought 2 Glocks with my LE discount for the 1 Beretta but it's a done deal.
I believe if I had the ability to own 2 handguns only, knowing what I now know, both guns would have the same operating system, same caliber and interchangeability, for me this means a Glock 17 and a Glock 19.
I'm not hunting deer, I can plink cheap 9mm, I don't fly fish in Alaska but I do live in a concrete jungle with 2 legged savages.
I was never a Glock fan but I am now. Reliable, simple, light, easily customizable, inexpensive.
Sorry for the long reply.
