Glock 20 10mm Question

HighValleyRanch, you are correct sir!

no different than someone getting a .357 and shooting .38 special most of the time. the option for more power.

Except with the 38 Spcl. option in a 357 magnum you don't have to change barrels!:eek:
 
Shop around the net for some of the Sig 10mm. Seems the last I found was quite reasonable for 10mm and it closely mimics the original Norma loading. I know it's right spicey in my delta.

Well, if you want to keep the platforms strictly analogous and actually compare apples to apples, ...

There was the S&W 610 revolver which, using moonclips, allowed for shooting either 10mm AUTO or .40 S&W cartridges without changing barrels.

In autoloaders, barrel-swapping capability seems to make the most sense with the Glock platform, since with the 10mm models - provided you have the extra barrels - you can shoot .40, .357Sig, and 9x25 Dillon. All these cartridges will run using the factory 10mm mags and recoil assembly.

That said, I've also seen a couple of 10mm Delta Elites in my time that had spare, custom-fitted .40S&W barrels the owners could swap in. They used the stock 8-rd Delta mags with the .40 cartridges and had no apparent feed issues.
 
Now if I were going to get a second barrel for my G20, and I probably will, it's going to be a 9X25 Dillon. You know, the round that makes the 357 Sig look like that V8 with two cylinders chopped off.:D
 
OK so I don't think OPs idea is bad. Get a G20, get a .40s&w barrel, and practice cheap if that's your wish.

I would not recommend shooting a bunch of .40s&w out of a 10mm chamber. I don't care about stressing the extractor, that can be replaced easy enough. My concern is the the round is not head spacing properly. The bullet is actually set back a touch from the shoulders in the chamber, and I would be concerned that shooting the short 40 cases could shave a little off the projectiles. Over time those shavings could alterr the headspace in the chamber. It wouldn't be a big deal, until you do it a lot and then got to shoot stout 10mm when the chamber is a few hundredths shorter, leaving that much of the head of the stout 10 mm load unsupported by the chamber. That high pressure round needs all the case head support it can get or you get separation. And that will make your gun kaboom. Just my thoughts on the matter.
 
Get the 40 barrel.

I got a 40 cal Lone Wolf and have many hundreds of rounds through my Glock 20 with the 10mm mags and standard spring.

No problems at all.
 
I have seen where 20/29 owners have ran 40 S&W out of their pistols without a conversion barrel .. I have maybe 50 or so to see it the fed .. They did .. was accurate ... I really see no reason to though .. Piece of mind 100 bucks ... for another barrel ... I may get one for my 29 ..

I think .40 in a Ten is pole-vaulting over mouseturds. Use a .22 for volume firing practice.

Maybe but I think it's mainly you that thinks this.

Guys I'm going to go ahead and do it! Getting a Glock 20 Gen 3 SF and an aftermarket .40 barrel.

Been eyeing this for some time. The only thing I don't like about the Glock is the lack of a safety or double action trigger. I like to keep my nightstand guns out and ready to access so the striker-fired Glock will have to go in a holster as I don't trust the trigger to be exposed with a round chambered siting on the table. I plan to use Double Tap 155 grain loads for home defense usage.

Places like Aim surplus have .40 cal glock police trade ins for around 350 i think (0nly the baby glock 27 at the moment) After you pay for a barrel how much more are you gaining over spending 200 or so more for a whole other gun? Id look around and buy both guns.

Fuzzy math? :confused: Why buy two guns, a 10mm & a .40 Glock? ... Not to mention the different magazines both require, and holsters (if the O.P. want to EDC one or both)?

You pay what?, $150 max for a stock-length .40 drop-in tube for a G20? Several barrel makers out there.

How's buying a second "L.E. trade-in" .40 Glock cheaper than the aftermarket .40 barrel alone?
 
Um lets see. Buy a barrel only for 100 or 150+ pick your flavor. Or spend 350 on a whole other gun and not shoot the wrong chambering in a possible defensive firearm. To me spending just 200 hundred more is worth having 2 firearms. A justifiable expense. Not to mention, how much will the 10mm be shot and or carried to justify all the expected magazine and different holster system purchases? Probably not much. Kinda like going to costco and buying in bulk.
