I go Glock 20. I am just beginning the CCP process here. Will be 60 days plus. Once that arrives, I will be looking at more options. Doubt seriously, I will switch, or go smaller. My G20 has been near by for 20 plus years.
I was a 1911 style guy. Cocked and locked, I prefer the double stack mags, and I prefer the 10mm cartridge over the .45. Both rounds will get the job done, the 10mm just holds more rounds, punched a little stronger. The Glock is also just a little lighter by reducing iron where plastic is good.
I call Glock Male Tupperware.
