Glock 20 10mm

After a long search, I finally found a new Glock 20 unexpectedly at a local pawn shop.

I traded a guitar for the gun, and promptly took it to the range. Accuracy was as good if not better than any semi-auto pistol I've shot, including 70-series Colt .45 auto, and recoil was noticeable, but not particularly harsh. In fact, the full-size Glock 20 doesn't really snap the wrist with 175-grain Win. Silvertips any more than does the Glock 26 subcompact 9mm with +P rounds.

Oh, and does the 10mm perform. It is basically a moderately-loaded .41 magnum in a semi-auto pistol...with 15+1 firepower.

How has this gun/round been so overlooked? It is ideal for home defense, as well as outdoor carry in areas where feral pigs/black bears might be present. In fact, Ted Nugent packs this gun at all times, including on his hunts.

Thoughts?

I want a 10mm, but ammo is awfully pricey, although it shouldn't be too bad for those of us who reload. I go back and forth on whether to get one of these or a G21 in 45. I'll probably just wait, hope, and pray for Glock to come out with a Practical/Tactical 45 and forget the 10mm unless I find a smokin' deal. I would like that kind of power in a reliable auto

when the FBI was looking for a better caliber/penetration thru barriers cartridge,about the same time skirts started joining the FBI and couldn't handle the recoil,although Txluckysob posted that the ammo never has been developed to maximize the potential,but i'll bet Uncle Ted has an ammo wizard conjuring up a potent batch for his 10mm battery with a flip of his wallet.

G20

I never leave the city limits without it. I don't think its been overlooked at all. Most people that need 10mm are well aware of the G20. The reason it's not a popular defense round against two legged threats is because its simply not needed. There are plenty other calibers that will do the job with less recoil, less potential for over penetration, and for less $$. I'm my opinion, 10mm can't be beat for handgun protection against four legged threats. I can empty almost all 15 rounds of 10mm from a G20 in the same amount of time it takes me to accurately empty 6 rounds of .44 mag from a revolver, and with 200gr and 230gr cast bullets and hot loads, I feel pretty comfortable packing it in bear country.

Runaway- you can get a 10mm conversion bbl for the 21, and the 20 mags fit perfectly. two in one.

No shit?

Well, I may have to start looking around for a 21. Thanks.

overlooked?

Nahhh...

Firstly, the G20/G21, esp. pre-SF frame, are like carrying a box of Wheaties. It's a big damned gun and plenty of shooters' hands don't fit it.

Secondly, the 10mm remains a dark horse....plenty of folks have never heard of it and have no idea what it is or what it's capable of. Combine this with the FBI's downloaded ammo and the increased cost of the cartridge and it gets pushed to the periphery of knowledgeable shooters.

The 10mm, properly loaded, is indeed good medicine for lots of lower-48 critters. Uncle Ted like CorBon in his; I recall him taking a warthog on an African hunt a while back with their hot 135gr JHP loading.

The G20 can also be quickly converted to .40SW, .357SIG, and 9x25 Dillon with a barrel swap....9x23 Winchester is another neat one; requires mag tweaking though.

conversions

Didn't know about the ability to convert the G20 to other calibers...

Got to love Gaston Glock and his modular mindset.

and a 21 can be converted to fire 10mm, can a 21 be converted to fire all those other rounds?

don't know

I've only seen 10mm bbls for the 21, but haven't really looked into it that much myself. TX probably knows. I think they have .22LR kits with replacement slides as well. I would assume it can be done if someone makes a .40S&W,.357sig, or 9x25 bbl for the 21 slide. You would use the 20 mag.

I've seen the .40S&W and .357sig for the 20, but you still use the 20 mag.

On the 21 conversion to 10mm... remember that the 20 slide is thicker and has more support than the 21. I realize the conversion bbl is supported, but not sure what effects from the pressure of hot 10mm loads would have after time on the 21 chamber. Probably wouldn't hurt to add a stiffer recoil spring also.

I had a 10mm bbl (pretty sure it was a KKM) for a 21 years ago. I didn't use it much, but never had any problems with it when I did. After I got rid of it, I missed the 10mm, so I just bought a 20SF.

I'll probably get a 21

but I gotta get my DPMS LR308 first. The only reason I even want a 21 is to have another Glock, so I probably won't even be able to justify it to the wife. 3 grand for a rifle will be tough enough until she uses it to kill a few pigs or coyotes.

G21

While at SHOT show, i asked the rep for GLOCK about gen 4 G21s. He did not have any information, does anyone know if this has changed? are the gen 3 better or should I wait for the gen 4 if it is going to be released?

From what I understand

Gen 4's do not accept any other gen mags???

Gen4

I still haven't warmed up to them yet. I much prefer the 3rd gen... and with the 20 and 21, the SF makes a world of difference.

I'm pretty sure the old mags will still work on the gen 4 when the mag release is on the left side. They won't work if the mag release is on the right. The newer mags with ambi mag release cutouts should work in anything

Clint- G21 Gen4 w/ beavertail for runaway so he will finally STFU about scraping his sissy little hands. The last release date I heard was May of this year. They had one at the show

That makes sense

Just read on another forum that as long as you do not flip the mag release to the right side for left handers the mags work...

My sissy hands?

Yeah, okay, my sissy hands. I'll accept that. I keep them soft so Nitris's dog doesn't complain too much.

I think I'll stage a protest outside Glock in GA until they agree to make the P/T in .45, the carbine, the revolver, and an AR.

Oh, and an AK variant with wood grips and a polymer receiver for Nitris's retarded ass.

my fave

Shot it again today.

I own four Glocks and this one is by far my fave. I've only put around 150 rounds through it (some cheap ball ammo, Win. Silvertips, and hardcore DoubleTap stuff). This is a substantial weapon.

Accurate, reliable, and it feels good knowing that there is power galore here.

I don't miss the Stratocaster I traded for this fine pistol.

10 mm

Sorry I am so late to this post. I just can't make up my mind about the 10 mm. I mean what is it really for. It is on the heavy side for self defense. It is on the light side for protection against bears and such if one lives in an area in which that type of threat exist.. I mean the 357 magnum pretty much has demonstrated that it can handle two legged threats with about 500 ft lbs of energy and proper bullet sellection. For those that like autos you have the 357 sig, the super, the 9 X 23 winchester, the 9 mm +p+...45 +P, 40 SW..etc which generate similiar pratical capabilities. The 44 magnum which by many peoples standards today, is a light weight in comparison to some of the pistol cartidges out there now..454, 475, 460, 445, and 500. The 44 can easily generate 1000 ftlbs without breaking a sweat. The 10 mm is not in that ball park. Nor is it really in the same league as the 41 magnum with serious loads.. so what is it for? Having said that, I still would like to have one. I just don't know what I would use it for.

what the 10mm is for

Ironmike15, have you shot a Glock 10mm with hot loads (i.e., 1350+ fps and 740+ ft/lbs m.e.)? The recoil is what I would describe as sharp...but not harsh. Muzzle rise is minimal.

I own a .44 magnum Ruger SBH, and I've fired Buffalo Bore bear loads that have more than 1600 ft/lbs of m.e.

I'm a big dude, and I have to say--these rounds are the limit of what I can handle. VERY harsh, and muzzle rize is around 80-90 degrees. They are on the cusp of what a .454 Casull can do, but damn are they harsh.

I've never shot a .41 magnum, but I do know that no .41 magnum exists with a 15-round magazine.

DoubleTap makes a 165-grain round in 10mm that deals 1425 fps and 744 ft/lbs m.e.--from a 4.6" barrel. My Glock 20 has a 6" barrel--which adds at least 100-150 fps. That is serious magnum power, with minimum recoil, from an easy-to-shoot-handgun.

Granted, it's not great for concealed carry and it won't substitute for a rifle in any way...but I just have to say that I smile every time I fire my G20. What an awesome weapon. I don't feel under-gunned in the least in the South East...

. Ninja ..the fact that your pistol makes you happy is a fine reason to own one. In fact , if you keep telling me how much you love it , you will probably convince me to buy a delta 10 mm. It wouldn't take much.. I do think it is a very interesting round.

stompy

IronMike, the 10mm is one stompy round, and I see it as appropriate for almost anything within reason. Get some underpowered FMJs for target shooting, get DoubleTaps for self defense or hunting. I do love a 1911-style gun, but I don't know how the recoil will be in the Delta (as you know, the polymer frame in the Glock absorbs some recoil). However, even in a steel-or aluminum framed gun...I can't imagine it would be unmanageable, and this is really one of the best medium power handgun rounds that I have found.

Am I going to hunt deer or feral pigs with this round? Probably not...at least actively. I would definitely not go after black bear on-purpose with a 10mm...more like a .308 or 12-gauge with rifled slug barrel and Brenneke's. However, if I happen to have this puppy on my hip...I will not be too terrified should one of the creatures venture too close to my comfort zone. Follow-up shots are FAST...

10 mm

Yea I don't think the recoil would be bad at all. I remember several 10 mm being marketed as hunting pistols. They were long slides like yours. I would hunt with it for sure if I had one. I think it would do quite well with medium game and heavy loads.
I am glad the round is making a come back and that there are some good factory loads for it. It would have been a shame for it to die.

You are right. The bren ten almost killed the cartridge. Pistol cartidge development is really odd. They keep inventing things that already exist and then say its new. I mean why shorten the 10mm to 40 sw...I mean just load it down or up depending on use or ability. Does that shorter size really make that much difference. The 40 sw is virtually the ballistic twin of the 38-40 black powder round of 100 years ago.. so they invented a truly impressive round and then went 100 years backwards.. and tell us its new and the best. Strange

Isd, I am sure you know the FBI did issue the 10 mm. It was too much Pistol. For them. They had an FBI load that basically is the 40 sw now or that how I understood it to be. The same fate as its ballistic cousin the 41 mag which was specifically designed for LE. The military should have adopted it but the military and many others were constantly infatuated with anything that says 45.. LE and military never seem interested in correct. Caliber choices
