10 mm glock


April 12, 2008, 07:38 PM
I shot the 10 mm Glock compact at Glock day here at Philadelphia Archery and Gun. I found the recoil to be surprisingly pleasant. I was really expecting something brutal. The rep from Glock said the compact uses a 2 spring system to help soak up recoil and that the full size Glock may have more recoil because it only uses one spring and can't be changed to the two spring system. I was very impressed but was wondering about the recoil on the full size and why they don't use the same system on the compact.

I think the system was designed by another manufacturer, I can't remember now if it was keltec or seacamp, but anyhow, Glock uses it on license for the G29. I don't know if this is the reason why they don't use it on the G20. I think size is the reason.

When you're talking 10 mm, ammo counts for a lot!

Double Tap's 135 grain, 1608 fps, 767 ft/lbs Noslers, will out-boom most .357 magnums at the range. Not quite brutal in my converted G21 (with 22 lb recoil spring), but with Magnum Authority, for sure! ;)

recoil is not bad with a G20 at all. I have not shot a G29 yet... but I quess I need to seeing all the very positive reviews. If I could CCW here in NJ I would be all over it, but since I live in a politcal cesspool, I am in no rush.

Like R&J said with the 10mm it's all about the ammo, the over the counter FBI light loads are similar to .45 ACP , but you definatly feel the difference with DoubleTaps hot loads

200gr CCI Blazer is nothing like .45ACP. I'm not sure what you are talking about.

Actually, Glock uses the same guide/recoil rod setup in the G30.

No full size glock uses this setup. They all use the straight recoil/guide rod with single spring. The idea on the compacts is to relieve some of the stress on a smaller frame and cut some of the perceived or felt recoil.

Most 10mm ammo is more stout than even the hotter .45 ACP. Regular ol' CCI Blazer 200 grain 10mm practice ammo is rated at 490 ft/lbs and is running about 1050 fps. .45 acp 230 gr. +p isn't even doing that. Remington 10mm practice ammo is 180 gr. and doing 1150fps/529ft/lbs. Fact is, this is somewhat lukewarm for 10mm. ProLoad and DoubleTap can bring you all the way up to the nuclear levels.

I have been considering a G29 myself.

On another thread it was also pointed out that the G29 and 30 were easy shooters. Not much was mentioned about the recoil springs and the borrowed technology though.

I have played with a lot of recoil springs to see if it makes a difference with the various (specific) loads. Staying with one spring for a light load and a different spring (heavier or lighter) for another.

It does seem to help if you dial the spring in like you do the round you are making up for your own purpose. I don't think most really get that specific because they believe the makers designed it, they tested it and what they put in was the best for the gun and caliber.

The guys who are Colt 1911 fans will know what I am talking about, they have been tweaking those pistols for a long time:D

Harley, what springs have you found that worked great with each specific gr. round?

You use DoubleTap rounds?

I plan on getting a G29 myself soon, and was wondering about recoil, and how to reduce it with "hot" DT rounds, since I plan on using DT for self defense, and would like the least recoil possible, so I can do double and triple tap shots, as fast and accurate as possible.

I was reading about "Dead Bang" recoil reduction system, and read it was around $85 to buy, but it's a lifetime moneyback guarantee if you don't like it, I believe. Anyone else read about this system? Do you have it? It says the system is good for fast multiple shots, and doesn't work that much if you're simply shooting slow shots, 2-3 seconds apart.

I did not specify the pistols I was changing springs on. I don't have a 29 or 30am not sure about them if you want to tweak.

I have tweaked the G22 when using the 357 Sig barrel and dropping below the 125 grain bullet. I then reduce to a 15 pound and have gone lower with the 85 grain frangible rounds. I have springs that go from 11 pounds to over 20 pounds. In my 1911 I use a 2 stage spring for the 400 corbon and +p 45 rounds.

In the Mdl 21 I use a heavier spring (than factory) for the 400 Corbon and +P 45 also. Some will say it is not needed, but to each his own. I have dropped to a lesser weight spring for faster shooting but don't advise with heavy hitters.

The springs I have are all from Lone Wolf. The set up (dead Bang) you are mentioning, I have read about it I don't use it. Here is something on it.


I have also gone to ported barrels with the 357 Sig 6" (mdl 22) and the 400 Corbon 6.5" (mdl 21) as it said in the above linked post the porting helps, noise is usually louder also. I also have some shorter barrels in 10mm along with a 6" that is not ported, you can feel the power;)

Many of the 10mm loads available over the counter are pretty mild.

It's best to compare them to .40S&W loads. If a 10mm load is only moving like 50-75 fps faster than a .40 in the same weight, then its a 'mild' load. ;)

The 'goal' or target load of the 10mm design was a 200gr bullet moving 1200 fps, or ~640ft/lbs.

If you don't want to roll your own, or don't want to buy DoubleTap ammo, there is one factory load that I know of that is very good for the 10mm.

Winchester Silvertip (175gr) for the 10mm is a good load, close to optimum for Delta Elites. It will shoot it all day without having to change springs.


Distance(yds) Velocity (fps) Energy (ft/lbs) MidRange (inches)

Muzzle 1290 649 -

50 1141 506 0.7

100 1037 418 3.3

I have not put any of this ammo through the chrono, but it is close to what I load for my 10mm.

I should buy a box and chrono it, it would be interesting to see how much winchester fudges their data, if any.

I agree. The only factory ammo I use is the Silvertip and
Double Tap.

Being hot for a Glock 10mm at one time. After shooting one at the local indoor range.. with some somewhat wimpy ammo (200 gr.Blazer) I no longer have a desire for any Glock 10mm.
But that is me.I don't like shooting Glock .40s either.
Others have no problems.

Glocks are great guns, and the 10mm cartridge is flat out

"200gr CCI Blazer is nothing like .45ACP. I'm not sure what you are talking about."


And 200 grain CCI Blazer is nothing like the Double Tap I described! Try some and see for yourself! ;)

i think they were saying the cci 200 is even harder kicking than the 45
but they are really a different kick too the 45 is a slower kick the 10mm has a bit more sting

"i think they were saying the cci 200 is even harder kicking than the 45

Understood! I'm still sitting on some of these, myself. Nice target ammo. But believe me, they are mild compared to the hotter Double Tap .45 ACP and 10 mm loads! ;)

Like all CCI Blazer I've tried, they are clean burning and reliable. But for me, the whole appeal of 10 mm, is the magnum-level power! In 10 mm, DT's all I shoot now! :evil:

For self-defense? Forget about it! 10 mm rules! :D


P.S. The attached is offered in good fun...

I've never fired CCI 200 grain 10mm but after looking up the ballistics ,1050 fps; 450+ fpe,they are similar ( as in not quite the same but close) to DoubleTap's almost +P .45 ACP, and niether of those loads comes close to McNetts(owner of DoubleTap) 180 grain controlled expansion( XTP ) bullet at 1350 fps;728 fpe. I have a Lone wolf 6" 9x25 barrel for my Glock 20. DoubleTap's ammo for this caliber is just mind boggling.....10MM + DoubleTap = POWER... other than that "felt" recoil is a matter of individual interpretation... what i think is moderate, you might think is hand numbing

I have a model 23 and a model 30, both are over 10 years old. And my 45 glock is a pleasure to shoot, where the 40 caliber has more torque and a nastier kick. Maybe it's just me but I always found a 45 much nicer to shoot, than just about any of the larger caliber weapons. Both are "stock" from the factory, other than the ghost ring rear sight and front trijicon sites.

My M-29 Glock digests the Double Tap 180 grain rounds with ease. I am no fan of snappy recoil which is why I no longer own my .40 Sig. The 10mm, often thought of as a brutally recoiling round is, to me, very pleasant to shoot. The captive double spring guide rod is similar to that on my Kimber Ultra, another relatively easy recoiling pistol, even with full tilt 230 grain rounds.
