I don't get the accuracy comments about Glock either. I've owned several, from the 17 thru the 21sf, with compact versions of each, and if I did my job, they did theirs.
While going through mandatory 40 firearms training, I repeatedly got yelled at for what the FI called "marksmanship masturbation". From 3yds to 25yds, fairly rapid fire (2 shots under 6 seconds from holster back to holster), and slow fire, with my 21sf, I'd have a fist size ragged hole in the chest of my target, with a flyer or three, after 50rds or so. The FI wanted to count each individual hole. I was shooting faster, and more accurately, then the 1911 carrying folks, who all were having reliability issues.[ New 1911s, never fired by their owners prior to training, FI hates 1911s, especially for duty use, big xD fan with the sweetest xD 40 I've ever fondled. Completely gone thru and refinished by Robar, has a trigger no polymer pistol is worthy of, lol!]
All flyers were my fault. And most of them 15yds and in..
Glocks have, imo, redefined what a duty pistol is. Others have caught up to, maybe even exceeded, what Glock started, but Glock got the bullet fired. Still own a 4gen 17, wife carries it on duty, but went away from them for one reason, they got boring. Nothing else really wrong with them at all, lol, just boring.
BTW, only seen one Glock fail. A department issued 3rd gen 22 sheared off it's rear slide rails. Countless rounds down the pipe, never maintained and issued, and reissued, as many times as it was shot, if you held the rear of the slide down, it would still work, albeit as a single shot.
