So because it wasn't raining yet, I took the Glock 21 out for some shooting.
At 7.59 inches long, 5.47 inches high, and 1.27 inches wide, it's not a small pistol. But then I didn't buy it for concealed carry. This one is my "project" Glock. When finished, it'll have a threaded barrel for a suppressor, tall night sights to see over the suppressor, and a light/laser combo for CQB use. Oh--and a suppressor. It'll then do permanent duty as my bedside gun holding 13+1 rounds of some highly effective .45 ACP personal defense round.
Things that go bump in the night would be well advised to go bump someplace else.
