My first was a Glock 22 Gen. 2 bought in 1993-----why did I trade it?-----Why? Why? Why? Then in 2000 I got a Gen. 3 Glock 22 and traded it. I have meandered around looking for the ideal handgun and I had it twice. I was in hot pursuit of a Gen. 3 22 but decided on the Gen. 4. It has the 28926 Extractor and the 0-1-4 RSA. 15 rounds of 180 grain jacketed hollow point fury traveling at 980 plus feet per second with over 430 ft/lbs of force you ask? That's what I'm talkin' bout'.
