I’ve had a G21 since about 1993. First one was a 2nd gen with at least 15k rounds through it (policy wouldn’t allow me to carry it on duty). Malfunctions could be counted on both hands, or less, because I don’t remember any. Sold it to get a 3rd gen with the light rail.
My 3rd gen does not fill me with confidence. I was getting the “light strike” LAPD problems with it…very, very frequently. I stripped it down and found that the striker block was not being lifted high enough to clear the striker, which was all peened and buggered from hitting the block. I happened to have an old gen 2 upgrade kit for the 21 in my bag, and replaced the trigger w/ trigger bar and the striker, noting that the old parts appeared to be nickel plated and “slick” while the new parts weren’t… Couldn’t change the striker block, since the old was a smaller size than the new.
Now it at least goes bang. Ran it through a Jeff Gonzalez class last summer without problem, but also without a light on it.
Now, when it is in my tac rig with an X200 on it, I get a mysterious fail to feed (hardball) periodically. This likely has something to do with the light on the rail.
G21 used to be IT (only hi-cap duty style .45 available, besides H&K). Worked great for me. Grip size was barely too big for me (works without gloves, but wearing gloves adds just too much). The G21SF just has a smaller grip (very good) and ambi mag release (I don’t need it) and Picatinny rail (OK).
There are just many more options now. I’d swore off S&W after being forced to carry a 659 and Sigma for my first 9 years. Just tried out the M&P and have to say that I really liked it. Haven’t tried the XD. Still would show up to work with a 1911 on (openly) the day they say I could.
BTW, all I do now is plain clothes and UC style work. Concealment is largely a matter of dress. Just did a UC shot the other day while wearing a full size 1911 and two spare mags. Not my first choice, obviously, but since we didn’t have time to change, we made do. I find the 1911 conceals easier because it is flatter. Besides, it isn’t a “cops gun”, but having it in a holster defeats that argument, since bad guys typically don’t use holsters.
