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 (http://www.glocktalk.com/forums/showthread.php?p=16609599#post16609599) [Note this is using factory ammo]

Jeff Quinn at GunBlast.com test fired the Gen4 G21 on a Ransom Rest (http://www.gunblast.com/Glock-21DE.htm) and shot a 1-3/8" 5-shot group from 25 yards with Buffalo Bore 185gr +P LFHP ammo (http://www.gunblast.com/images/Glock-21DE/DSC04189.JPG).

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 (http://www.glocktalk.com/forums/showpost.php?p=18987279&postcount=7).

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:supergrin:......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.

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

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 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.

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.

That is a steady hand! What sights are you using? Do you find most loads can achieve this or is it a specific load?

Thanks

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.

Hello Sam,

Factory sights, standard self defense ammo. Best I can do with training ammo is 1.75-2.2" groups at that distance.

Please note I said FEET, not yards! :)

I have 4 Glocks. the 21, 36, 17, and 23. As strange as it sounds I can shoot them all with about the same accuracy despite the differences in sight radius. For all 4 of them combined I have about 22K rounds through them and the thing that seems to make the most difference in accuracy (not counting how different I may be from one day to the next) is what Ammo I'm using. All my Glocks are very consistent and very accurate and I have the utmost confidence in all of them.

I have a G21 Gen4 and it is my "under the bed gun" and it is as just as accurate of any Glock I own. If I was active again and on patrol I would want the G21 gen4. Carryring 14 flying ashtrays is the way to go.

Is is safe to shoot 45 Super in the Glock 21? Can it shorten the life of the gun?

Perfectly safe and reasonable wear and tear with a stronger recoil spring of at least 21 lb or 22 lb. If you intend to reload the .45 Super brass, an aftermarket barrel with better chamber support is worthwhile for best results.

Whether it's prudent and reasonable to load .45 Super for urban CCW is another question. For me, the answer is definitely no. Precisely measure split times on follow-up shots with .45ACP vs .45ACP +P vs .45 Super and you'll have your answer. Ask Mas Ayoob about .45 Super for CCW/HD in the Glock Talk GATE Self-Defense Forum (http://www.glocktalk.com/forums/forumdisplay.php?f=256) to get some expert advice.

I load .45 Super in a G30SF only for woods carry where dangerous critters aren't expected in the area. The pistol is in .460 Rowland or 10mm config for hikes and camping in the habitat of more dangerous game. One of my pistol instructors hunts deer successfully using his hand-loaded .45 Super ammo and a Glock 21 pistol with 6-inch barrel.

I dumped the 21 for a HK and never looked back.

The Glock was too thick and clunky and it wasn't very accurate in my hands. I'm not saying it's not a accurate gun because I've seen people print some nice size groups with it. It just didn't work for me.

NEOH: do you have problems with your HK going randomly back to double action when it gets a little dirty? I didn't care for that about the USP.

When I shot competitively I'd clean my G21 about every 1,000 rounds. Had zero issues in the 20 years of ownership.

That's an important post in that the G21, it the right hands, does well. In the wrong sized hands, not so well. I would be remiss if I didn't make it clear that in my hands (bigger), I do well and get good groups. However, put a M&P .45 in my hands and I do a shade better.

That being said, much easier to work on my Glock at the armorer level. :)

That's about how often I clean my range pistols. I'll clean my carry pistols every 2-400 rds. or about every other time I train with them. Once I stopped shooting WWB, my guns don't get super filthy anymore.



Since grip/hand size was brought up there somewhere, something I noticed the other day: G4 21 slides into and out of a custom leather holster with retension screw and rubber grommet I have made for 20/21 easier than my G3 20SF. In fact it also fits much better in a cheap uncle Mikes kydex holster made for the 20/21. There has to be some minute difference in frame width since that is what the holster really holds to, not the grip or slide. Could be just the trigger-guard but my guess is both or the frame.

My G21 is plenty accurate thats for sure! However, I think that some of the people here need to think about competition. I shoot bullseye league and what with the number of you that can shoot 1.5 or sub 1 inch groups at 25 with the G21 all the time, you should be competing!

Where in the world are you finding the "flying ashtrays" at? Speer hasnt sold that bullet in quite a while. Unless you were referring to the 200gr Gold Dot, which is not the flying ashtray.

I don't usually go off the bench for my G21, but it is absolutely, irrepressibly accurate. I do the "chase the hole" drill, which is where I shoot a bullet hole and try to shoot the rest of the bullets into that hole. This is from probably 40' and every bullet touches. Every. Last. Bullet. I've been shooting it so much that it's becoming more accurate in my hands than my brother Kimber Custom (Blasphemy you say!). Also, I'm 5'9 and 155 lbs. I don't have huge hands, but it fits me very well and is such a soft shooting gun. I recommend the G21 to any and everybody looking for a .45

My 21 is very combat accurate but ive never put it on a bench. I know for a fact not as accurate as my 1911 and i can shoot my friends glock 30 just as accurate as my 21. If something bad went down id rather have the 21 than any pistol i own. First chance i get i'll put it on the bench with my reloads and some factory loads just to see how accurate i can shoot it.
