My first Glock was about 25 years ago, a G21. I sold it and went with a Glock 21 about 20 years ago.
I owned a gun store, so I was always handling different handguns. Never found one I liked better, or that shot better for me.
The high capacity mags is a real plus. I like 1911's, but I am never going back to half rations of ammo again.
How could someone do a trash a Glock video and forget to heckle the safety trigger system? The only weakness I have found in Glock is no exterior safety, which I rectified with Safe-T-Blok.
