I don't see the need for a 10 mm in a small gun. If 10mm power is really needed then the G20 should be used otherwise the G33 or G27 will be adequate.
If I were ever to buy some more Glocks, I would want a G20 and a G31

In my experience; the model 33 loaded with full power sig loads is the “snappiest.”
I.E.: it has the fastest recoil impulse, not necessarily the most powerful impulse.
For most powerful impulse; it’s my carry gun. A model 29 with my hand loads.

That said; neither of those come close to my LCR 357 with UW loads, or a S&W 629 with Garret Hammerheads. But that’s not what we’re talking about here, is it?;)

The 9x25 has been fun to get to know. I'm loading a 90 gr JHP to 2100 fps. It is probably the light bullet mass that makes the difference in felt recoil.
Yep. Even though the FPS is high, the PF is only 189. Getting a 200 gr up to speed with 10mm can get over 240 PF. That's a big diff. Takes a little more powder for the 10mm, and as we know, more powder = more snap.

The worst i have shot is Airweight with Buffalo Bore +p 158gr, I thought the gun was gonna break, and 158gr 357 mag in Lcr, Snappy to me.
My Glocks.... 30s,20,23,27 don't compare.

Right about pf, incorrect about powder charges. Lighter bullets get a heavier charge for a given pressure. In the 9x25 vs 10mm example above, the 9x25 uses almost five grains more Accurate No. 9 powder than the 200 gr 10mm load.

Generally speaking, for a given pressure, heavier bullets must have a reduced charge compared to ligjter bullets.

EDITED to add. Powder charge is more closely related to muzzle energy. The 9x25 has 880 lb/ft, whereas the 10mm has 700 lb/ft. Granted there are different barrel lengths and cartridges in play, so not a perfect comparo -- even though both are shot from the same gun. But the same would hold true if I swapped for a 135 gr 10mm vs 200gr. Charge would increase for the 135, as would ME (north of 800 lb/ft in my ammo). Lower PF.

I do...I want a 10mm single stack pocket rocket!!
It would be easy for Glock to make a 10mm on a G36 frame. A longer grip would give you more ammo capacity and help with recoil management. And I honestly don't think recoil would be that extreme.

The 10mm may be the magnum of semi-auto cartridges but it's more like a 41 Special compared to a 41 Magnum. I have a G20SF and even with the hottest loads, recoil isn't even worth mentioning. On the other hand I have a model 58 41 magnum and that is downright painful to shoot with the hottest 41 mag loads and the standard service grips even with a Tyler T-grip adapter.

Hogue grips help a lot but I can't stand to look at that beautiful classic blued, pinned and recessed S&W with rubber grips on it.

Or you could just get a G20 and get a 357 Sig conversion barrel for it.

KKM makes the best aftermarket barrels. I don't know if they make a 357 Sig conversion barrel for the G20 but if anyone is interested, here is their contact info:

So do all the orthopedic surgeons I know. Great for wrist business.
I have a 10mm 4 inch 1911 pistol and its super fun to shoot.


There are few auto rounds that are that hard to shoot. 500 s&w magnum .. 460 revolvers.. hot loaded 44 mag from 2.5 inch scandium revolvers . That is wrist snapping stuff.

A 10mm glock 29 or 20 ?? A glock 36 ?? A glock 32 in 357 sig ?? They dont require a doctor to repair your arm or wrist.

Ever shoot a 300 ultramag rifle ? 416 rigby ? Etc. Those have recoil.
My daughter by age 12 would put 50 rounds thru a 300 win mag.. bolt action rifle.

I didn't know that. My thought process said it takes powder to move a bullet, but considering case size with bullet size, I see where it can differ. Thanks. ;)

My G32 handles great...recoil is easy to manage due to the largish grip. However, my G33 twisted in my hand under recoil with hot Underwood loads. This altered my firing grip and slowed down follow-up shots. I solved this problem by putting a Pearce +0 magazine extension on my carry magazine and using the G32 mag for a reload. This eliminated the problem and helped me to tighten up my groups at the same time.

The first round is always snappy. By the end of 400 rounds, it is barely noticable.
Like climbing a ladder; the first time is shaky. After the 20th climb, feels pretty stable.

Repeated dry fire reinforces that first round experience, not the 400 round experience.

For me it was the G27 and then went to the G26.

I think the G29 is a *****cat, possibly the most overhyped Glock regarding recoil, even with DT, BB or Underwood. It's one of my favorite 10mm's. I think the G36 is the nastiest pistol to shoot as far as recoil bite goes.

And so we see... YMMV... Everyone's different.
