Tell me about the 10mm

[jmay]

You know i have been thinking hard about a Glock 20. May even trade my 45 Blackhawk.
Tell me the good, bad, and ugly about the 10mm. I do reload so guess thats a plus.

[Nick_C_S]

I have a G20 SF. I've had it for just over a year. I have about 500 rounds through it, or so.

You reload, so that's "the good." Ammo is expensive and hard to find. Reloading 10mm Auto yields particularly good savings. Myself, I bought a Lone Wolf aftermarket barrel for it, for range trips (for SD, the stock barrel is in it). The LW barrel deforms the brass less; and that's better for reloading, obviously.

There's lots of "goods," actually. If you like recoil, it's real good If you like reliability, it's real good too. It's my nightstand gun.

The only quirk I've experienced with it is with hot factory ammo (HPR 180 XTP), it will sometimes go into slide lock on the second-to-last round. I don't think I'm bumping it, but who knows. I'm also in California, so it's a 10-round mag. So anything goes with that. I guess we'll call that "the bad."

And as far as "the ugly" goes; well, it's a Glock. Can't help there.

I love mine. But I wouldn't trade a 45 Blackhawk for it. But then, I wouldn't trade anything for anything. I just don't.

[jmay]

You know the Blackhawk for whatever reason has just never grown on me like i thought it would. Think i might just sale the Ruger,dies,brass, & stuff and give the 10mm a shot.

[reticle]

I have two guns in 10mm. My only complaint is that the brass gets chucked a fair distance away; which for an aging reloader such as myself, is a bummer. Don't know if that is typical of all weapons in 10mm though. Some have a hard time controlling the gun under recoil, but that has not been my experience. I like that I can make some spicy rounds and load more of them in a mag than .45acp will accommodate.

Love my G20! Not many semi auto hands can offer the power and capacity of the Glock 20.

I may add a Glock 21 to my collection as I want to add another caliber the 45 Super.

I like the 10mm, and I like it in the G20. The cartridge offers sufficient power over the .40 in realistic ammo to be attractive. The 10mm is often criticized as being down loaded and not offering up the power it promised. My 10mm reloads, very safe and from the manuals, show a useful gain over .40/180 of about 275 fps. That from the std barrel length of the G20 and a Browning HP. I see that as comparing a .38 to a .357 and good enough for me.

The G20 is flat and relatively compact as a belt gun (no bigger than a Blackhawk, that's for sure) shrugs off abuse and some neglect, and has been stone cold reliable. I had to change the sights to get POA/POI (fixed factory) but otherwise no issues whatever. The high capacity is a comfort in some instances, and if nothing else, a single mag seems sufficient for any woods romp.

Brass does not seem that hard to come by, though loaded ammo can be.

We loaded the 10mm down to about .40 power and the G20 still ran quite well, and bamaboy shot IDPA with it for a few months (cause we had it). And you can buy a .40 aftermarket barrel and shoot .40 if you so choose, or so
they say.

I've thought about trading mine since the G41 .45 came out, but the cartridge offers more punch and I still entertain the idea of taking a whitetail with mine.

I have had 10mm for over 20 years and it is a keeper for me. If you don't max load it all of the time it is pretty easy on brass as I actually have usable brass as old as the gun. For example, my favorite 180 load is 10 grains of Blue Dot (Hornady lists 10.7 as max) that gets me 1252 fps from my 10mm 1911. That load is accurate and hits hard enough for anything I need. Another favorite is a 207 grain SWC that I cast myself. I load it to just under 1000 fps and it too is accurate, cuts nice holes in the target due to the SWC design, and really penetrates well due to its mass. Again, I could load it hotter if needed but that load just works so well as is. YMMV

I've got 4 10mms...Gen 2 Glock 20 with 6" Lone Wolf barrel (for hunting with lead bullets, a Gen 3 29sf for my edc, a Dan Wesson CBOB and a S&W 1006. Obviously I like the round. The most versatile (IMO) handgun cartridge around. Not a whole lot it doesn't excel at (with the proper loading). You really need to buy from the small online dealers or reload to really take advantage of the round.

[JERRYS.]

no ugly. the bad? some same ammo but good stuff can be had from the factory. the good? can be loaded with factory ammo from .40 cal power, 45acp power, to 10mm magnumesk power.

[jmr40]

I have a G-20, like it a lot. In don't see the 10mm as worth the effort for most people though. If you are just shooting at the range it is too expensive. For personal protection from 2 legged threats the better 40, 9mm or 45 loads are every bit as effective with a lot less hassle.

But my 10mm fills a very specific and important role for me. I spend a lot of time hiking and camping in Georgia and Tennessee where black bear are common, and incidents are becoming very common. With the best loads I can get true magnum revolver power from a much lighter, smaller gun better suited for hiking/backpacking.

I carry Double Tap 200 gr ammo loaded @ 1300 fps in the woods.

I buy practice ammo here.

Not a good pic, but a it makes the point. Here is my G-20 beside my 3" Smith 629. The Glock is 1" shorter and 3/4 lb lighter. From the 3" barrel the 44 just barely beats out the best loads from my Glock in power. MOst folks look at 44 and 357 loads quoted from 8" barrels. From 3-4" barrels they are not all that impressive.

While I really like my Glock, the only time I ever use it is when in the woods. If I didn't hike and camp in these areas I probably wouldn't own one.

I think the 10mm cartridge is a versatile cartridge and should be more popular ! I'm relatively new to the cartridge myself and have tried mild to wild loads....however , my DW Razorback seems to like 180 grainer's going about 1250 to 1300 fps the best ! Unless the big animals escape from the local zoo...I see no need for more power ! I plan to hunt deer with it not so much about protection !

[jmay]

Hows the recoil of higher end loads in the Glock 20? I have shot plenty of top end 44 mag loads out of 629s and SBH how does the 20 compare?

[Nick_C_S]

I have both sizes of Glock 10mm. One is my carry. And one is my nightstand. (Note: the G29 happens to have the Lone Wolf barrel installed at the time of this pic.)

Recoil with full-house rounds is stout; but not up there with 44 Mag.

In my 20's, I was a recoil junkie. Now that I'm in my 50's, not so much. I'm an average size guy. If I shoot them with full-house rounds, they both (G20, & G29), get to beating me up after a hand full of mags (again, 10-round California mags).

For SD, both of mine are loaded with Federal 180g Hydra-Shock ammo (product ID: P10HS1). They are "de-tuned" slightly. In the smaller G29, they chronograph at 1030 fps. That is still plenty stout and is more powerful than a 40 S&W (yes, you can theoretically load a 180g in a 40 S&W to achieve 1030 fps, but you'd be pushing it to its absolute max - not recommended). I have tremendous confidence in this round for self-defense.

I also load a round to emulate the Hydra-Shok for practice. I handle it well and they are comfortable enough for a full-length practice session at the range.

[JERRYS.]

if you spend time in the woods its a great round. if you reload its a great round. if you like power its a great round. if you like versatility its a great round.

that said, I have a G20 and G29 both with meps N.S. and about 500 rounds of factory ammo for trade locally for a G21 and G30 and at least 250 rounds. why? because I have plenty of .45acp stuff already.

[jmay]

What kinda critters you guys taken with the 10mm (not asking about brown bears) ?

[NorwegianShooter]

Shot the Glock, Bren-Ten and the STI Perfect 10... Perfect 10 is hands down the most awesome of the 3...

[rope2feet]

Finest 10mm handgun ever made. You can probably find a new one on gunbroker.com. The quintessential firearm / cartridge package to acheive optimal DVC

[Hunter0924]

The 10mm Auto is a fine cartridge and my favorite handgun caliber. Since you reload you can download it to .40 S&W velocities if you want light practice rounds and go to the other extreme for solid hard hitting defensive rounds and all points in between.

Here are a few articles I have put together, some history and ballistic testing.

G20 and G29 owner here. What can I say 10MM exceeds what I want from it!
I want to add a S&W 310 or perhaps a 610 to round out my 10MM's.
I can't really come up with anything bad to say about it!

[rock185]

jmay, admittedly biased 10MM shooter here, since the days of the first Bren Tens. In fact, I had a new Bren Ten, Colt Delta, kimber, S&W autos and revolvers, Glock 20, Ruger 38-40/10MM Blackhawk converible, etc,etc. Recoil is not a problem. Pretty mild in comparison to the .44s, etc you've shot. I cannot say the 10MM is better than caliber X, Y or Z, but I still enjoy shooting it. It does shoot flatter and have more energy than .45ACP, etc. It will knock down steel targets,etc, at 50 and more yards and more better than .45ACP, if that matters. Some of the smaller ammo manufacturers still load the 10 closer to it's true potential. A lot of the major manufacturers seem to have loaded the 10 down closer to .40 S&W level for years though. That old Norma 200 grain load really did do 1200 fps, or a little more most 5" barreled guns I tested it in. More recently, the 180 grain Buffalo Bore I chronographed averaged 1350+ fps. Not bad for a service sized, easy to control, pistol caliber. I've reloaded for the 10 since dies became available and still enjoy the 10mm myself.....ymmv

DVC

Col. Jeff Cooper summarized what he calls "Modern Technique" with the acronym D.V.C. This abbreviation stands for the Latin words "Diligentia, Vis, Celeritas: or "Accuracy, Power, & Speed." These three terms correspond to the Modern Technique as follows:

"Diligentia" - You must hit your target in order to cause him harm.

"Vis" - You must hit your opponent with enough force to incapacitate him with as few shots as possible.

"Celeritas" - So that no harm comes to you, you must hit all of you opponents quickly.

D.V.C. was as much the personal motto of Col. Cooper as it was the motto for his Modern Technique and he passed this motto on to all of his students

NorwegianShooter-Thank you for asking.

The late Colonel John Dean "Jeff" Cooper had a vision of the 10mm cartridge, looking for a 40caliber 180gn bullet at 1,050fps out of the 5" barrel. Dornaus & Dixon working with guidance of Col. Cooper designed a combat pistol chambered for the 10mm, ammo as loaded by NORMA exceeded the specs, providing a 170gn JHP at 1,300fps and a 200gn JTC at 1,200fps.

Anything and everything 10mm firearms and ammo drop in to this forum. Many enthusiast who share the passion and preservation of this great cartridge and the guns to launch these ballistic missiles!
