For those who own a G21, how accurate is it for you?

For those who own a G21, how accurate is it for you?

I'm trying to find out what the range in accuracy tends to be for those who own a G21 with the factory barrel, and shooting commercially available ammo.

I've heard this gun is more accurate that many other Glocks, and I don't know why that might be, so I thought I'd toss it out to hear from owners what kind of groups they tend to get.

Thanks so much.

Mas Ayoob: "I've seen the G21 do 1.5" or a bit less at 25 yards for 5 shots, off the bench, but I've seen the G30 do UNDER 1.0". Reference: Glock 21 And Glock 30 [Note this is using factory ammo]

Jeff Quinn at GunBlast.com test fired the Gen4 G21 on a Ransom Rest and shot a 1-3/8" 5-shot group from 25 yards with Buffalo Bore 185gr +P LFHP ammo.

Mas Ayoob writes about the inherent accuracy of the Glock .45ACP pistols in his book, "The Gun Digest Book of Combat Handgunnery". Read the excerpt here: Massad Ayoob on the Topic of Glock Accuracy.

I've had 2 or 3 occasions when I put 5 shots just under an inch with a G21 at 50', indoors, on a 'bench'.
These were all shot with handloads-5.5 gr WW231, Rainer plated 230gr FMJ.Don't remember the primer type.

Love this gun. Very manageable recoil especially in Gen 4 and it will routinely make a golf ball sized hole shooting about a round a second at 15-20 yards.

I've plopped my 21 onto a bench top at 100 yards and put every shot on an 8" target several times. Mind you I was shooting it a LOT back then but it is super accurate. The inherent accuracy differences are in the barrel as the 21 has an octagonal barrel vs hexagonal on the others.

Easy 1.5 at 20 to 25 yards. Most of the time its well under 1.5. this is with factory. Now with handloads......under or at 1.0 all the time if I take my time for 5 shots at 25 yards. Its a 2.5 generation. I will never sell it. It and my Glock 27 in .40 S&W...never to be sold..never.

Regards
Orange.

BTW, the above was achieved with handloads only. 230GR FMJ, 231 Winchester powder out of my Dillon SDB reloader. That powder bar is ingenious and never moved out of the .1 grains accuracy in all the checking I did over the years.

Well mine is all factory! I'm shooting 3" Offhand at 20yds & 1" on a rest at 20yds. Sunday afternoon I shot my manhole cover target at 100yds off hand easy!

My G4 21 is very accurate. More accurate than my other G3 and G4 Glocks in 9mm, .40, 10mm and 357auto? I doubt it, about the same.

Most Glocks are more accurate than most of us; meaning if someone can shoot your Glock better than you can or a bench rest nets tighter groups, it's plenty accurate enough for you.

I believe 357auto is one of the most accurate due to many things including close, consistent velocity spreads. It's also flat-shooting so that helps as the shot's get longer.

They're all more accurate than you are. The 21 is not notably more or less so. Enjoy.

I was shooting a lot last summer and ran some accuracy tests at 100 yards, offhand. My listed group sizes are with any shooter induced flyers removed. Group sizes are rounded to the nearest inch.

G21 Gen3 with after market sights

Buffalo Bore 230gr HP +P 10"
Hornady 230gr FMJ FP reload 9"
Hornady 230gr XTP +P 14"
Hornady 200gr XTP +P 10"

With a Storm Lake barrel the group sizes go down a bit.

I've only shot my Gen3 G21 at 25 yards or less but it is very accurate, more accurate than I am. Factory sights too. Had a guy offer me $700 for it the other day. He really wanted to buy it badly. Not selling, not yet anyway.

The old G3 slide finishes are in demand along with a proven, working Glock these days. I had a problem with one dipped G4 .40 extractor of four G4's I own. Replaced it with non-dipped and no more FTExtracts. The G4 21's seem to be flawless by personal experience and all accounts I've read and heard of. Good for you to hold onto a pistol you can shoot well and trust.

I think that I shoot pretty good and can usually do ragged hole 10-shot groups at 7-10 yards with my 21gen4.

I had a Gen3 21SF for a while and never particularly cared for it. In my hands, it was not very accurate. While it would certainly have done in a pinch, and was 100% reliable, the groups I shot with it were much larger than I could shoot with pretty much any other handgun I own, then or since. (among many other pistols, I own three other Glocks, a Gen3 19, a Gen3 26, and a Gen4 23) So I gave it to my brother as a wedding present. He loves it. I love my other Glocks, just didn't care for the 21.

I don't know what it was with that 21 that made it shoot so sloppily. It didn't fit my hand very well, that may have been a big part of it. It never "felt right". It had the factory plastic sights too, which I've never been super comfortable with either. The night sights are much better.

I think you just answered yourself, Why.

If I do my part right with quality factory ammunition, I can easily get 1 3/4 inch groups at 25 yards. I preferred the SF frame myself for best results.

I can turn in a fist size group at 10 yards going through a 50 round box of range stuff like blazer or pmc just shooting for fun. It's mechanically way more accurate than my ability with it I'm sure. With better ammo and a better shooter I would think your results would be very satisfactory.

The heavier weight of the G21 improves accuracy for lots of folks. It somewhat counteracts some anticipation/flinching movements.

I couldn't agree more. I recently purchased a used gen3 G21 from someone in need of $$$. Knew nothing about Glocks since this is the first one I have ever owned. I love the way this gun shoots. Is it big and bulky, sure, but it operates flawlessly. I'm not sure why the G21 gets such a bad rap.
