Mine is Glock 21. I know, they're ugly and have zero sex appeal. What they do have is utter reliability, and I shoot it well. In twenty six years of qualification, training, etc., the only trouble I ever had with it was weak magazine springs. Changed those out and it went back to total reliability. Besides, the serial number is my badge number, and it has the agency seal on its slide. I think they charged me about $350 for it when I bought it from the agency. It's been a pretty faithful companion!
