Same here-I found no discernable difference between my G21 and a G21 SF that would justify my getting a G21 SF. And a very experience senior LEO and IDPA shooter of my acquaintance much prefers his G21 to a G41; the G21 apparently provides better recoil control characteristics...
Best, Jon
We were in G21s at the start which was 1992 (2 digit prefix) and I got mine in 93 (AFN710 still recall the serial number).
We were breaking extractors at the start because the ejection port was cut at 90 degree and we had to send our slides back for a 15 degree cut.
We would experience misfires either because of limp wristing from weak shooters or cheap, hard primer or concave base ammo that Admin was buying.
2011, We started replacing G21s with G21SF and Glock sent us ambi mag release models by mistake and mags were dumping on their own. Glock took them back and sent us SF models.
Modern times, our officers were complaining the G21 was too big.... so we eventually phased them out for G17/19 and now the big complaint is this gun shoots left! HA!
I put many a Full Ball down range from my original issued G21 till around 96ish and bounced around with SW4500 till 2008 when new Admin approved 1911 for duty carry.
Some of the original G21s from the early 90s had curved frames, but they still worked. I had to put plus trigger bars in them to make them pass spec. You could see more daylight in between the frame to slide in the center.
While this image is not our gun, its an example of either the frame rails set too high or over time the frame fatigued, but it still worked.
If you're going to be a bear….be a GRIZZLY!
I don't see any discussion on capacity or operating the safeties when in an entangled gunfight.
The Police Chief magazine experiment took non sworn and timed how long it took them to figure the safeties out. A better test would have been to leave a 1911 in the jail and see how fast criminals can operate it.
