I'm trying to justify a 10mm as well. Preferably an EAA Witness Hunter longslide. I don't re-load, or hunt, and I shoot a ton of 9mm for target shooting. I don't think I need one, but I think it might be fun to have a long range cannon. Especially after re-watching the ending of Death Wish 3.

 

Maybe you asked the question better. Thats exactly what im trying to do is justify the caliber.

 

The 10mm, the most powerful auto-loader cartridge that fits in a practical sized handgun of practical cost.

No, it's not a 41 magnum, regardless of what people say; bit more on par with the .357

While there's plenty of factory offerings, it really is a handloader's cartridge. Expect to pay a premium for full power commercial loads, the less expensive stuff is typically loaded to 40S&W levels.

To dip your feet I'd recommend a G20. Have fun

 

What is the primary use in why you think you need one.

If i buy another 10mm, the G20 would be the one that i would likely look into.

 

I bought my G20.4 3 ½ years ago.
For me, the only downside is ammo cost.

Pros, again, to me, are many.
I can shoot cheaper 40 S&W for practice, but I prefer to just use 180 grain 10mm, in whatever brand I can get at the best price.
When I go to the range, I shoot mostly my 9mm handguns, but will always have at least 3 magazines loaded to stay fresh on my G20 since it is my EDC.

Outside of target shooting, I can get loads that will take down nearly any threat you might encounter, and those hot loads are a real rush to shoot too!

I personally feel that 10mm, specifically the G20 is the most versatile handgun available.
I think that to get the most out of a 10mm a person should be reloading. I am not yet, but am saving brass and slowly tooling up to do so.

 

I was an earlier adopter of 10mm and on reflection it was a mistake.

im a reloader and after looking at reload data, its basically a 40SW with maybe another 100fps.
The price differential is not really worth it. The 40sw is identical diameter and slugs and buying ammo is way cheaper. Any gains w 10mm is marginal. My only 10 is a g29. Likely end up selling it at some point.

 

Me too. Just thought I had to have all of that power.
I started with Double-Tap and Swamp Fox ammo. That’s how long ago it was.
I’ve had a G-20 and G-29, G-20 and 29 SF, and a G-20 and 29.4. I ended-up getting rid of all of them.
I found the 10 to be a pretty good jack of all trades but master of none.
If I’m wanting defense against humans I’d much rather carry a 9 or .40 (.45 if I could make myself lug a 1911 around, but the G-27 just carries so much easier).
I also bow hunt in Colorado and Montana. I thought the 20 would be perfect for that. Nope. The 10 is okay but I’ve moved back to the .44 mag for “bear protection“.
The power of the 10, IMO, isn’t needed for BG’s and isn’t enough for the woods where bears are concerned.
The ammo cost and availability doesn’t justify what it can do, which to be honest, isn’t much more than any other service caliber and doesn’t come close to a .44 mag.
However, if YOU WANT one then you don’t need me (or anyone else) telling you to get one or not.
Just go in knowing ammo is more expensive and usually best attained by internet sales.
If you go that route, I’ve 2 pieces of advice for you:
1) you can shoot .40 ammo through it without modifications for some cheaper range time. Just google it and be aware of some things you may need to do.
2) open an account with Underwood ammo.
You can thank me later...

Been looking around for a 10mm but i'm really trying to figure out the caliber a little more. I would google but i'm looking for user experience information. Any information you can offer would be much appreciated.

P.s. My username doesn't mean I know everything clearly. Although I pretend to most of the time

Google search will get you plenty of personal as well as expert analysis along with the technical data, not just opinions.

 

I like my G20 and my 6" double stack 1911, I dont like trying to figure out where the shells launched to... the 1911 weighs in a tad under 4 lbs which really calms down the recoil a bit.

You can convert a G21 to 10mm with a conversion barrel and magazine change and you still have a very useful 45ACP.

One nice feature of the 10mm Glocks is their barrel-swapping capability.

All you need is any one (or all) of the aftermarket barrels in .40S&W, .357Sig, or 9x25 Dillion, and now you can shoot those cartridges too - using the stock 10mm magazines and stock 10mm recoil assembly. All are 10mm-derivative cartridges. Nothing else needed. Well, except the ammo ...

No need for me to buy a separate gun in .40S&W. When I want to play it 'light-n-fluffy' with, say, my most awesome G29, I do a quick strip down and install a LWD 'drop-in' .40 tube (stock-length), and proceed to plink away with cheap .40 range fodder.

Feels like a +P 9mm out of the G29 due to the large polymer frame and the heavier 10mm slide and recoil assembly.

Fun for a while until the boredom starts to set in ... Then you find yourself missing the testosterone-enriching feel of real 10mm ammo, and you sense the urge to re-install the factory barrel and get back to the reason you wanted a 10mm in the first place. :thumbsup:

That said, the saving grace of buying an aftermarket .40 barrel is that it's waaay cheaper than buying a separate gun in that caliber, along with extra mags for it, etc. You can play with it when you want to, and it packs easily enough in your range kit.

Several vendors make aftermarket barrels in alternate calibers for the Glock 10mms - KKM, Bar-Sto, Storm Lake, etc.

I got my LWD .40 barrel years ago. If I recall correctly, it was something like $110.

 

10mm is my most accurate cartridge.

I can shoot more accurate groups out of my g20 then I can out of any other full size pistol.

I am really found if my G29. It is about the same size as a g23.

I hand load. The notion that 40S&W is only slightly weaker than 10mm is a bit silly.

Sure you can have crazy hot 40S&W that are on par with lower end 10mm. That is true. But the upper end of 10mm is frightening.

Check out ballistics by the inch.

But in summary
40S&W out of a 4” barrel maxes out at about 580 ft-lbs

10mm our of a 4” barrel maxes out at almost 800 ft-lbs.

That is on par with the energy difference between some thing like 38spl vs 357 mag. Can you have +p 38 that approaches 357?

Can the neighbor kid tune his Miata to be as fast as my M3. Probably, but how much faster can my stock M3 be tuned to go?

Not to mention, 'crazy hot 40S&W' loads risk a KABOOM!

 

Got the G20 about 6 years ago and heave worked a lot with it. In retrospect I would have gotten a different brand. Its a tool and it works -most of the time. Finally bought a Sig P220 and it has been a delight. Its heavy at 40 oz and only holds 9 rounds, but it works so well, that I dont think I would need 15 rounds. Power level is in the lower 357Mag level with the option to go to much heavier bullets. As has been said, its the best handful of power you can get in a nice flat autoloader. It has been used successfully on predatory bears, advantage being the rapidity with which good power loads can be fired, unless your name is Miculek.
Reload, reload, reload. Cost to reload is of little difference in cost over a 40S&W, plus you can create and load between exploading marshmallows to setting the woods and your shirtsleeves on fire, with safety. 10mm-firearms.com is a good info source.

Which Sig 10mm model do you have?

Mine's the two-tone DA/SA Elite model with the fixed night sights. Unloaded, it weighs right at 44oz.

All good advice there, and 10mmFirearms.com is a great forum for all things 10mm.

 

My 10mm tastes have evolved the last few years. Had a G29 and the 10mm witness with the 4.5" barrel. Found them both to be sort of clunky, and not easy for conceal/carry. Both are gone. I have given up on finding a carry option for 10mm...wish they would come out with a 10mm shield.

I have had a few 1911's in 10mm, and a GP100 in 10mm. I prefer the 1911 platform for 10mm. I have gotten rid of both a Sig and a Rock Island double stack, and now have a Para double stack 10mm long slide.

I find myself leaving the 10mm in the safe more often than not when I want to go play on the range. I have a number of handguns that use less expensive ammo to punch holes in paper, and if I want to shoot steel or any other "fun stuff" I opt for a little more power, and yank out the 41 magnum revolver.

I have carry guns in 38/357, 9mm, and 38 super. My range toys are 10mm, 45acp, 41mag, and 500S&W.

I hate to say it, but if I had to give up a range toy the 10mm would be the first one to go. 45 is cheaper to shoot, and the 41 and 500 are way more "fun".

 

Love the 10mm. Had a G29.4 but, recently sold that and now I have just 2 1911s in 10mm. DW Valor and a Delta Elite. The DW goes wherever I go...

 

You`ve got 2 of my first loves. Just absolutely 2 of the most stunning 1911 10mm`s....PERIOD!!!
I still have my G29.4 though. That`s my truck gun, its a keeper.

Pro: You get to act like Billy Bada$$ with your 10mm.

Con: Unless you roll your own or buy expensive boutique loads, it really doesn't do anything for you that .40 can't.

Here's a good article on 10mm.

https://www.luckygunner.com/lounge/10mm-self-defense/

 

10mm is a fabulous cartridge for the great outdoors.

Not much fun to conceal day to day in urban environments unless you have coat.

IMO, it's best as an OWB pistol.

 

I carry a Glock 29 under a t-shirt all the time. The 20 gets the nod when it gets colder.
There's also a Dan Wesson C-Bob I carry occasionaly under light clothing as well.
My T-shirts fit well, not too big but not bodybuilder skin-tight.

It's not that hard if you're committed.

 

I’m a big dude and have no problems double or triple tapping my Glock 20. When I walk my dogs, I carry it with some hot Underwood ammo. It also travels with me in my truck wherever I go. Do some research and you’ll see the 10mm can dump immense amounts of energy into a target without overpenetration issues. And it’s fun as hell to shoot at the range. It is my favorite caliber.

 

The beauty of 10mm Auto is that it's basically anything you want it to be. It is extremely versatile, from the watery loads mentioned above ('...a 40SW with maybe another 100fps') to even less than 40 SW if one works hard enough, like a 200 gr loping along at 850 fps. Hell, how about even less (150 gr at 1000) than a juiced 9mm (147 gr at 1175)! But there's little confusion between a 200 grainer at the top end of each; 1,000 fps (40SW) vs 1200 (10 Auto).

I'm for variety. The lateral cartridges of 9/40/45 have become standard fare and serve their purposes well. The 10 adds some much needed spice to the range and superior terminal oomph should you want or need it.

 

Pro: Available in the perfect platform: Glock 20 Gen3 SF or Gen 4.
Con: Not yet available in Gen 5 or single stack compact.
Pro: Decent selection of ammo including Underwood which is XLNT and reasonably priced.
Con: Ammo not cheap unless you reload but plinking ammo is affordable.
Pro: you can shoot cheaper 40 S&W ammo out of a Glock with no modifications.
Pro: other guns are available for those who do not like Glocks.
Pro: PCC carbines are also available including affordable Mec-tech upper for Glock
Con: Glock does not make a modular PCC available in all calibers with factory extended mags for G20 and G21.
Pro: Suitable for woods carry and self defense against predatory feral humanoid recidivists.

 

If you want to be as cool as Chuck Norris, there's no more thinking to do.

 

I bought my first ten millimeter (a Glock 20SF) because I wanted to reload for the cartridge. It just offered such a wide range of options that I wanted to play around with it. There aren't too many pistol cartridges that offer a 100 grain range of bullet weights (from 120 grains to 220 grains).
And, obviously you can make the projectiles go very fast or kind of slow.
So, yay, I tried it.
The first discovery that I made was that the 10mm cartridge is very accurate. Hand in hand with that, I was shooting it out of the gun that Glock designed its large frame variant for, and it showed. The Glock 20SF handles the 10mm very nicely. And, once I had the bug, (no pun intended) I had to have the Glock 29, which admittedly, I found to be quite a handful initially.
Here's a fifteen round group that I put up freehand with my Glock 20SF at fifteen yards. Your results may vary.

 

I always liked the 10mm. I first picked up a G29 then a Colt Delta but it didnt get fun until I started to reload for it and I picked up a S&W 610. Full house loads through the 610 is a blast to shoot.

 

I kinda wish I still had my G29.4 but, now I'm interested in a S&W 1076, 1026, 1006 and so on!

I have the 1076 in 10MM. Absolutely love that gun.

 

Cool!

Post a pic of it...

 

You can convert a G21 to 10mm with a conversion barrel and magazine change and you still have a very useful 45ACP.

That's not the best way too go if want 100% reliability. The best way to have two 100% reliable guns in one is to get a complete 45 ACP G21 upper for your G20, or a complete G20 upper for your G21.

The case head sizes are different and the extractors are different and that's what causes reliability problems, more so with a 10-to-45 conversion than with a 40-to-9 conversion.

 

I had a 610 for a while, but the 629 would do much more in the same size package. I really have no use for the 10mm.

 

I tend yo agree in a revo. Fir the same size gun, I woukd rather run 41mag, 44mag or 45colt. The 10mm shines in a semi.

 

Thanks! Quite nice!
