What are you guys getting for accuracy with your Glock 20? I am curious as to what distance, bullet weight and barrel you where using (if not stock).

That's a pretty subjective question Buzz. Each shooter's answers will be different depending on whether he shot rested or offhand, hot loads or weak, FNHC or hollow point.

Suffice to say, my G20 is wicked accurate. Plenty accurate for hunting or common SD scenarios. A guy can give you numbers here, but what does that really mean to you with your G20?

I had the same question a few months ago. I've since bought my own 20 and can give you some round-a-bout numbers.

Glock 20C
Wolff Guide Rod and 22lbs Spring
KKM 6" barrel

I'm able to shoot 2" groups at 20 yards from a rest using Remington UMC 180gr. Obviously, that expands with distance. I find the gun to be much more accurate than I am.

Well said Opie, it is pretty subjective. With that being said, I guess I am just wondering if the Glock 20 is know for it's accuracy, overall.

My G20SF running my 180gr jacketed loads is as accurate as my best 1911 using my killer 200gr LSWC loads.

To give you some feel for how good this caliber and gun is, I only have two 1911's left and will soon only have one left. I just bought another G20SF. This is coming from a 1911'ophile.

Last time out, I ran 25rnds of AE 180gr into 4.5" at 25yrds offhand.
I don't typically rest or bench my pistols, but I'm sure it's good for anything I need under 50yrds.

9 rnds 3 1/2" at 50yds from a rest. Lone Wolfe 6" bbl, ATS sights 3.5lb connector (broke at 4lbs) and it was either pmc or umc ammo, can't remember which.

Both loads over book. ( HOT HOT HOT ) Off hand @ 50 yards. 686P fired double action. All slow fire. The 686P is more accurate than the G20. But the big 10 is a tame monster.

My 20SF appears to be a very accurate pistol as well. Can put entire mag on a paper plate offhand at 50 yards. Ammo Underwood 165 as well as some Winchester Silvertips. Only mods 3.5 connector and 25 cent trigger job.

Biggest issue I have is stock sights are way too BIG to use at this range. Looking to replace them with something a little more target friendly. Not to hijack thread but if anyone has suggestions here I would like to hear them.

My G20 groups very well with most loads. 10 rounds inside 1.5" @ 15 yards. If I were a better shooter it would be tighter than that. I have a pretty prounounced astigmastism in my dominant eye so it is tough to see fine targets at 25 yards.

I was blamming away at a 220 yard steel (18" X 12") gong last weekend offhand. When I did my part and broke the trigger on target, the rounds hit the target every time. I was shooting a 180 gr Powerbond fp bullet pushed by Blue Dot @ 1125 fps. I missed a lot, but "calling my shots," the bullets went where they were pointed. Blue Dot noticeably gives the tightest groups. Accurate #9 has shown consistently good groups too.

Bottom line, with good loads, the G20 shoots better than I do.

I can hit pretty decent at 100 yards with mine. For some reason my fairly hot blue dot loads do the best.

Man the G20 and other Glock OEM (stock barrels) barrels are as accurate as they can be. We have a particular place on the ranch to shoot out to 600yds. That is a loooong way amigo. No, I do not always hit what I am shooting at even with the big bore revolvers..

BUT, I can tell you the truth here that out at 300yds in this canyon, It is NOT at all uncommon to hit basket ball size caliche rocks against the red clay background with the Glocks, been doing it for years. Yes it does take practice and many years of shooting, and tons of shooting all the time. No magic about it....

I am simply saying that as per your specific question, the G20 I own, will pop these white caliche rocks, which explode like a sack of flour, when hit. And the G20 will and does (with my hand loads at least) shoot very well at 100yds, and yes I have misses, out further, but it is me and 61 year old eyes, haha, but I regularly hit at even 300yds these basketball size powderd rocks and targets. I see no advantage to after market barrels as for accuracy.

Hope this will encourage you. I shoot 98% Hard Cast bullets, but no matter what I am shooting, the G20 and all the Glocks I got shoot very well out at very long range. My revolvers, well, they shoot easier for me out there, but the locks are no slouch, and hold thier own well.

Really like the G20 10mm... Very nice weapon. The 10mm is a very good caliber and shoots nice and flat with a full house load and proper bullet..


Go with confidence, the gun will do it. Just practice and shoot a great deal and have confidence in the gun. It is a good shooter for semi auto ! ;)



Have fun!

I found my Glock 20 to be very accurate w. full power XTP and GDHP loads. No problem to hit 9 or 10 ring at 25 meters (27 yards) if shooter does his job well.. Full power (1250 fps) hardcast 212 grainers (23 BHN hardness) need an aftermarket barrel w. classic rifling for such accuracy. But even HC's are accurate enough with oem barrel if loaded lighter, between 1050-1100 fps.
I use 4.5" barrels - oem and IGB.

Remember there are 3 factors to accuracy. The gun, the ammo, the shooter. While I haven't been able to do a lot of accuracy work ups and testing, I've been considering those groups averaging 2-3" @ 25 yds off sandbags as good.

I am going to take a guess and say that his lead bullets run at least 200 gns.

I am of the opinion, without a lot of fancy numbers to it, after shooting a lot of .45Colt, .44 mag, .41 mag and a little less 10mm, that there is some sort of "ballistic coefficient/sectional density/ magic fairy dust" thing that goes on with 40-41 cal bullets at around 200-220 grains. (sort of like 6.5 rifle bullets around 140 gns and heavier). For all the accuracy I CAN get out of my S&W and Ruger .44s I can do as well with my Smith and Ruger .41s with a lot less "fiddling around" .

I am still "messing around" with my new 20sf but I have quickly come to the conclusion that it is noticably more accurate than my 22c. I hope to get some long range in before the end of summer.

Hey my friend...

Man I don't know about the "fairy dust" haha, but Your right about 200gr in 10mm... I use Beartooth 200gr HC at 21BHN, and shoot them out of the stock Glock G20 Barrel, and at 1200/1300fps they will pop those "caliche rocks" waaay out there with very good accuracy.

While I do have better results with my big bore revolvers and HC bullets, man I cannot fault the 200gr bullet Cast or XTP in a G20 for really good accuracy. In fact all the Glocks I have had/have now, all shoot out on the canyon rim (where we play at long distance with stuff behind the house) very well out to 300 yds. Those white rocks on the red clay canyon wall make for a really great shooting range when ya get tired of steel plates. They really explode ! ha.

I am shy a 41 mag in my stock of things at present, but like you, love the 44's 45's etc, and have shot them all my life and loaded about 98/99% HC for them all these years. Their my favorite shooting irons any way and EDC on the ranch.

Like you were saying about the 200gr and the 10mm though, it's like 22.0grs 2400 in a 44mag, or 18.5grs in the same, or 23/24.0grs H110 in a 44mag/45LC.... Seems like magic. I know you know what I'm talking about ! ;)


Hard to convience some folks on those powders and loads for the 44/45, but man I have been served very well with those in 250 Keith to 300gr LBT's in both those big calibers over the years.. Again, Kinda like your talking about the 200gr in the 10mm. Man it just works, (with proper powder/load).

Folks say NO HC in a stock Glock barrel... Man I been shooting 21BHN HC in the stock Glock barrels for 14/15 years with nothing but very good results. When ya can pop those Caliche rocks at those ranges out of the OEM and using HC, I'll take it ! ;)



Good shootin to ya amigo !

I have been casting RCBS 250Ks and Lyman 429421s in single molds for a while and am excited because I almost have my hands on an old 429421 double.

I need a good mold, and haven't found one, for my .41s. I have been shooting some 220keiths, cast by (I am not kidding) an old hermit who lives even further up in the hills than I do.

I want a 200-210 gn mold of as close to a Keith that will feed in a stock Glock barrel. AKAIC If you religiously clean the barrel you can do it. I might pick up an aftermarket barrel anyway for the heck of it.

I had to make my own holsters for my 4" N frame .41 and .44 for carry in the hills, to get the holster I wanted, There are more good designs for the Glock so, if I get the bullets I want it goes into the "off pavement" rotation. A lot lighter than my Witness.

Suggestion...

Call "Tommy" at Lead Heads Cast Bullets. He is a real good friend of mine, and his Keith molds for the 44mag are the original sister molds from ole Elmer himself. They were given to him by John Taffin, and some other boys years ago. His "Keith" bullets are the 'real dea'l, and ALL I shoot when "shooting a Keith." Just do not say to him "Keith style," He gets real upset with the word "style." Haha . Cause these are "Keith bullets." The best on the commercial market.

Seriously, he "may" just be able to help ya find what your lookin for. :dunno: Worth a phone call... ;)



We're about 5 hours from a city, and a real loooong way from a town out here on the ranch. Being a 'hermit' ain't bad amigo ! :thumbsup:




Good luck with your project

All Glocks are more accurate than I can shoot.

However, I must say that I shoot tighter groups with my 9mm Glocks than with the 10s. Since the 10mm recoils more, it takes more practice to shoot better (something I'm still working on).

At 25yd, I can keep 9mm groups about the size of a drink coaster, while 10mm groups are about the size of a paper plate. For defensive shooting scenarios, both of these distances are way further than I'd ever need to take a shot, so I feel confident knowing I can hit the enemy.

I get quite a few 2-3" groups from the bench at 25 yards and, on a good day or a month I've been doing a lot of shooting, I can do the same at 50y. The pistol will be better than you are, most likely. I shoot using both a stock OEM barrel and a stock length fitted Barsto. The Barsto barrel is definitely more accurate but both will suffice if you do your part. PRACTICE!!

Reviving a old thread here!! But its a subject that's near and dear...

OP IMHO your best answer was your first one.. Opie hit it spot on. The range os shooters ability, proficiency and if rested or not make the answers you'll get all over the board!!

My own G20 is a great shooter. I am a long time bullseye shooter with a Master classification in pistol. SO when I say mine shoots 2'' at 50 yards off a rest and one hole off hand at closer ranges. These are with hunting or ''full house'' loadings. Take that with a grain of salt.

This was 25feet offhand.

If you ask Glock, they'll tell you the GAP round does it all. Heck, they'd even tell you a GAP bullet will bring your targets back to you if they thought you'd buy one.

I am convinced that the G20 is more accurate than I am.

G20SF, stock 4.6" barrel, 165 gr. Underwood TMJ & GDHP. Stock sights. Ghost Rocket connector. Slow fire, no support. All targets are letter size paper.

I'm going to throw out and old timer's thoughts on this. I have been studying firearms since I started mowing lawns at age 12 to earn the money to buy gun magazines. That would have been about 1972.

I have come to the conclusion that some things "just are".

That is to say, despite all the numbers you can crunch, they don't explain everything. For years it was thought, that when both were driven at full throttle with factory ammo, the .41 magnum was a bit faster than the .44 magnum, but most gunwriters felt it was less accurate. A funny thing happened when reloaders too to it. They went with different bullet weights and even committed the unthinkable---they loaded it at les than max velocity!!! They loaded it with 210 -220 gn bullets at around 1,2000 fps and found that its accuracy became impressive. Indeed the tightest 20yd group I ever fired with a new to me handgun was with a Ruger Blackhawk .41 just so loaded.

If that load sounds somewhat familiar it should to 10mm shooters. It is in the ballpark of thee 10mm, especially if you do a little juggling for .401 v .410 .

On top of that there is the platform we are discussing. I admit to being completely unimpressed with the accuracy of the Glock 9mms that have crossed my path, I am not saying that the accuracy is terrible at all, but I have always had at least one or two other 9mms that have been more accurate, and I am talking about service autos.

My G-22c is the least accurate of the four .40 cals I own. Not terrible accuracy at all but simply not as accurate.

So we come to the G-20 SF. Not any special modification to the basic Glock Design, just on a bit different scale for the cartridge. Yet, my G-20 I markedly more accurate than the G-22 and is right in there with those accurate 9mm and .40s I have, not just with most of them, but with the best of them. Same holds for my .45s. and couple of them commanded a premium because they were built FOR accuracy. SO how can this be? I don't use the word "surprising" in terms of accuracy, I think it is overused, I prefer "unexpected". So why is the G-20 delivering it?

I think there are factors, as my Dad used to say, "that don't fit on a slide rule". For all I know it might have to do with "the frame flex in that frame size works to create the perfect harmonic effect with the wall thickness of the 10mm barrel" It could be that the velocity of the slide divided by the mass of the slide multiplied by the weight of the recoil spring (in grams) when divided by the square root of the muzzle energy, yields a magic number known to be divine among the ancient Mayans and, by some ethereal coincidence the Tibetan Buddhists .

On the other hand, maybe some thing just are. :dunno:

If I do my part the gun is plenty accurate. This past year I tried off hand training out to 25 yards and beyond for the deer season. You appreciate the necessary skill to develop kill zone accuracy consistently.

That is some nice shooting. Nothing ambiguous, subjective, or hard to figure out about that. 50 yards, nice groups, enough shots fired to support conclusions, grouped well and obviously not a bunch of fliers that might have been clear off the target.

Clear, concise. Nice shooting. Nice post. Thank you.
