Not needed.
Because of "regulations" I had to carry a Glock 17 [9mm] as a work gun for several years. I carried 2 of them at all times.
I carred the No2 in my left front pocket, round chambered, and never had any "suprise" rounds fired...
While a Glock 17 "ain't no" 1911, and it "ain't no" 45 ACP...
It is a very reliable, shootable, and rugged hand gun.
It is one of the best non 1911, non 45 ACP handguns on the Planet...
