View Full Version : G20SF softer shooting than G35

I took both to the range today. I started off with the 10mm but when I switched over to the .40 I felt a much sharper, intense recoil than with the G20SF. I'm still more accurate (so far) with the G35 but I was surprised that the 10mm was more forgiving and more pleasant to shoot. Simply amazing.

They were both handloads shooting the same bullet but the 10mm used 7.2gr of Autocomp while my .40s were loaded with 5.6gr of Autocomp. If I could get brass at the same price as .40 brass I don't think I'd shoot it much. Yep, I'm diggin the 10mm more and more. Now if 10mm is more powerful than the .45acp and can be loaded down to .40s&w levels remind me why I would bother with those cartridges any longer.

I'm kidding (mostly) since I still have other guns to shoot but I am considering converting my guns to 10mm. It just seems to make sense. Now if I could only find 10mm as easily as 9mm....

The difference in recoil you mention doesn't suprise me. .40's a nasty little compromise of a cartridge. I have some 10mm Prvi Partizan ammo that has .40 ballistics, (180gr @ ~950fps), and it's extremely "soft shooting" in my G20-SF, (the 10mm's longer casing permits this). The casings dribble out 1-3' to the right. Full power 10mm e.g. Underwood is 180gr @ ~1300fps. That's a huge difference, and significantly hotter 10mm loads exist.

Firing Underwood from my G20-SF, I wouldn't describe the recoil as "sharp" or "intense". It's quite managable. If you've got a good grip on the pistol, the muzzle rise isn't even that bad. Recoil is noticably greater than when firing lesser 10mm of course, but you can feel the polymer frame absorb a lot of what would be greater felt recoil if the pistol were all steel.

After owning and shooting a G20 for 3 months, and having previously owned a P226 in 40 S&W, I conclude that the 10mm has less recoil than a 40.

I won't doubt your experiences, but have to ask, what 10MM ammo are you both shooting?:dunno:

If the question was referenced to me:
I never shot Swamp Fox or anything like that, I bet that would recoil a lot.
I load my own, no factory ammo.
I usually load to max level of reload data available for 10mm using Unique and Power Pistol powders.

I've only shot my hand loads and Hornady ammo. I havent shot anything hot. But comparing the 10 & .40 I know the 10 had almost 2 grains more powder but felt noticeably softer. I'm not sure if "sharp" or "intense" are the correct adjectives to use but with my G35 the explosions felt more pronounced. It seened like the larger frame soaked up more of the "shock".

I've been shooting .45acp for the past 15 years and. 40s&w for the past year so the 10mm was just surprisingly soft shooting. When I start shooting hot rounds then maybe things will change but so far I like what I've been experiencing.

Gotcha! Try a pound of Long Shot, Blue Dot, or 800x and load up accordingly, with the 10, and get back with your results. I have no experience with power pistol, but many years of loading Unique. You cannot achieve top performance loads in 10, or 44 mag with Unique, and, can understand why your 20 seems softer shooting compared to some 40 loads.

shoot some 135gr noslers @1600fps, 180gr @ 1350fps, and 200gr @1250, and get back to us! I was smiling ear to ear when I did!

Oh really? I usually shoot 180s in .40 so I simply used the bullets I had on hand. But I could try some 135gr & 200gr for giggles and grins. Which powder are you using and do you have load data? I'd like to try it out (eventually) but of course I'd work up to it.

Right now I just have a mostly full jug of Autocomp (burns so clean) and Titegroup (way dirty for almost all of my loads) so I'd like to blow through them first. But I could buy some 1 lb. bottles to try out.

(Edit/Add) ....I really need to get a chrono now. Maybe I'll ask Santa.

I dont reload, yet. But there is lots of good data for achieving said velocities in the 10mm reloading forum. Even though I dont load myself yet, Ive read two reloading manuals and lurked around the reloading forums here for a long time. Im very close to being able to afford all the equipment I want. To get these velocities, most people have to use either 800x or longshot..

Reboot, go buy some 155gr Hornady XTPs, and some Blue Dot. Load a work up starting at 12.0gr, and move up to 12.9-13.0gr (using CCI 300s, and a COAL of 1.260" for all loads). I would consider 13.0gr a near full-power load (and a safe maximum with Blue Dot). The blast and flash will wake you up, too. For 180gr bullets, 10.5gr is a great, accurate, mid-full power load, and 11.0gr about max. For real, full-power 10mm loads, buy 800-X. But Blue Dot will meter better, and is a good all around 10mm powder. I understand that 10mm likely does recoil less than .40S&W with those loads. It's likely because of the heavier G20 slide, and thicker grip, but full-power stuff will be a good bit stiffer.

Please be safe and properly work up to these MAXIMUM loads.

Here is a teaser picture of me shooting that 155gr XTP/12.9gr BD load from my G29. No tricks, it's real:

Thanks 21Carrier. I think I may get a lb. of Blue Dot and 800x just "to try" and I'll see how I like them. I'm not as recoil sensitive as I used to be but it was only after shooting the 10mm back to back with the .40 that I noticed the difference.

I'll work up to those loads but I have to find a place to shoot around here (The Bay Area) where I can shoot more than just paper targets. I'm sure I'll have to really drive a couple of hours to find anywhere good though.

Thanks again for the info.

BTW - Awesome picture. That is what I was expecting with 10mm.

You won't see quite that much flash with the G20's longer barrel, but that load should still be plenty beastly. Plus, 12.9gr BD, CCI 300s, 155gr XTPs, COAL 1.260" is a published max in Hornady's manual, so it's a safe load. I've shot about a thousand of that load. I've gone up to 13.3gr without issues, but didn't gain any velocity with my short barrel. That load will be a lot of fun at a range. People will be wondering what the hell you're shooting. The blast is pretty loud. It's a fun load, and it will give you a good idea of what 10mm can do while still being plenty safe.
