I found a good deal on a EAA witness hunter long slide in 10mm. I'm going to have to find a new load for it or new sights because when I shot several shots at 20 yards, only one ragged hole appears! Doug said it was the most accurate auto pistol he's shot, even better than his Smith 41. Its drilled and tapped for scope mounds, but not sure I'll bother!
My one shooting buddy and I took turns shooting at numbers, letters and bullet holes in targets....none were safe. Commonly one shot is all it would take! Yes its muzzle heavy with a 6" barrel and full length slide, but it shoots soft too. This is my first 10mm, though I inherited a few hundred brass in a deal I made a year ago, no dies or bullets yet. I'll have to either down load ammo and/or get a heavier recoil spring. 20 or more feet is too far to be looking for brass! (No adverse signs on the primers of the S&B factory ammo I used)
So far I'm loving it and might use it for USPSA matches for fun.
I hope to go hog hunting with Janet and my brother this year, perfect sidearm for it. (Maybe a dot sight would be good)

Sounds like yers shoots as bad as the one my brother had. The Witness Hunter is a dandy pistol. He never put a scope on his, didn't need it.

If you think the slide speed is too high, you won't get anything out of putting a heavier recoil spring in it. The only thing a heavier spring does is closes the gun faster, which is the full intended design of the spring. To reduce slide speed, buy and install a flat bottom firing pin stop first. That changes the dynamics of the leverage it takes for the gun to push the slide open and backward. If that is not enough, install a 25lb hammer spring with the flat bottom firing pin stop. Changing these two items will not effect the trigger at all. I also shoot a 10mm long slide 1911. I've made those changes to mine and you can't believe how the slower slide speed effects felt recoil. It's lighter in recoil than my 40SW Baby Eagle with 135gr HPs. It's like shooting heavy 9mm. But, and this is why brother sold his, expect the gun to throw the brass into the next county with full house loads. It's a common complaint with the 1911's chambered in 10mm. Before I made the changes on mine, it would throw brass 75feet with full house loads. FWIW, S&B and PPU 180gr ammo is pussycat ammo. Most of it chronographs at around 1050'ps despite what it says on the box.

FWIW, right now American Reloading has the 40 caliber Federal HST pulled bullets on sale for CHEAP. If you reload, don't wait as they don't last long. I shoot the 180gr HST at 1300'ps out of my 6" barrel using 12.8grs 2400 powder. Blue Dot is another good powder for the 10mm as is AA7 and AA9. Starline brass seems to be the pick everybody prefers.

The firing pin retainer is quite squared off, I looked at that first. The gun comes with 3 recoil springs after the first few shots I put in the heaviest one and that cut the empty flight path down to 20 feet from 25-30. I might get a scope mount for a red dot for low light hunting, and only use it for that.

I was shooting a Colt Delta Elite for some years, back in the late '80s/early '90s, and by far my favorite powder was AA#7. I am told that the newer powders are somewhat better than #7, but according to my groups and chronograph, that would be really hard to prove. I'll strongly recommend #7 as a good starting point.
I also used AA#2 with cast bullets for giggles, and it didn't hurt a thing, either. I ran it for some IPSC matches back then, and did quite well with it, too. I had put a Heinie compensated barrel barrel on it for IPSC, but went back to the factory barrel for most of the shooting I did. Fun times.

Excellent.. you know we expect pics and a shooting report so you're on the hook. AND I would be at all surprised if you just HAD to have a 10mm AR to match now, :D

Pickt up an EEA 10mm 5" a while back. It's a brass chucking sob but shoots good considering one if the slide points is broken. Been meaning to send it back for repairs.
The 10mm has proven to be a hunting round, am thinking about selling the SRH in 454 Casull?
