I own a H&K USP Compact in Sig .357 and I am having all kind of accuracy problems. I have no problems shooting a 1.5" group @ 15 yards with my 1911's but this guns just does seem to hold up to what I thought it would do. This gun has about 1000 rounds through it and is unmodified from the box. Any suggestions would be appreciated.

1911freak,

Sights and trigger on a USP arent in the same league with a 1911, so you probably won't get the 1.5"@15yds. from this gun. I only say that because everyone I know shoots a 1911 better than most DA's to varying degrees.

I've fired or seen fired many many USP's and I cant recall a bad one to date. The 357 SIG is a pretty accurate round too. My own compact in 9mm will cut a ragged hole at 10 meters all day long, as long as I do my part.

Try shooting the gun from sandbags taking your time. Se what your results are then. It could be the gun or you at this point, at least with the info you've given so far.

I dont think your expecting too much from a USP to give you 1.5"@15yds., they are easily able to deliver that kind of accuracy.

I'm very surprised, my personal .357 sig USPc will do 1" @ 15 yards with Speer GD ammo.

Can you explain your issues further?
Perhaps it is the trigger or something about the gun is not quite "right"?

What ammo have you tried?
Does all of the ammo suffer from the same accuracy issues?
Do you print low with the USP?

I have tried Speer, S&B, and Federal. I have the same problem. I admit it could be the differences between the 1911 and H&K .357 triggers but I don't think so, I take a slow measured pull and don't jerk. I don't aim low. I don't think it's a sight problem, I think if it was a sight problem they would group together consistently. I really think this is a good gun, no FTF's nice action, but not sure what would cause this problem.

1911Freek,

I shoot the USPc 357Sig also (had two, sold one). My first 357Sig was spot on right out of the box and would shoot 1" groupe at 25yds (no BS here really) my other 357Sig sprayed all over the place and need a couple of things to get it right. First off the front sight was too high. Once we got that corrected we still had large groups(even from a sand bag rest). I had an HK Certified Armorer look at the trigger and he said "it sucked!". He did some serious polishing to the trigger components and that help emencely. Groups shrank from 2.5+ to 1.5 at 25yds. He told me that I should have sent the gun back to HK when I first purchased it and they would have fixed it under warranty.

So I say to you give HK a call and let them fix it.

Oh and BTW, although S&B makes some good ammo their 357Sig is crap. The 357Sig round is designed arround a 125gr bullett and S&B utilizes a 147gr bullet. Neither of my guns like the S&B and groups are 5" at 25yds vs 1"-1.5" groups. I have also tried some hot 115Gr CorBon stuff and they work well but the 125gr rounds work best.
