I recently got an H&K USP 9mm Compact, used, with no manual. I can't quite figure our how to disassemble it. Can anyone help me?

Also, it this pistol safe to fire with Federal 9BPLE, their +P+ load?

Thanks.
 
Remove the magazine and work the slide to cock the hammer and check to make sure the chamber is empty.

Then move the slide back until the little notch on the left side lines up with the front of the slide release lever.

Push the pin out and the whole slide release lever will fall out, then pull the slide forward and it will come off.
 
What boofus said.....then remove the recoil spring and barrel and you've pretty much got it.

Just note the relationship of how the recoil spring fits onto the barrel lug so that you can reassemble correctly.
 
Thanks everyone!

It worked as advertised. Got it apart and cleaned it up, AND got it back together properly.

But this leads to another question. I noticed that it seems to have a polygonal barrel similar to the Glock. Does this mean that the H&K has the same prohibition against lead loads?
 
I hope you got a good deal on it. The last USP I saw before I fled to New Hampshire was $850.

:cuss: 'ing Reilly.
 
"I hope you got a good deal on it."

I traded a Glock 19 straight across for it. I think the sign on the H&K was $595. I paid about $375 or $400 for the Glock a few years ago. The Glock was gone within an hour and the guy who got it was very happy with his purchase.

Do you think I got a good deal on it?
 
There are USP deals out there to be found. I got my USP40f variant 1 for $425 very slightly used. Maybe a box of ammo through it.

I shoot lots of lead out of my USP9 Compact. It won't run with soft lead. Get some hard lead or linotype. I clean the bore after every range session which lasts approximately 300 rounds.

Just because I don't have any problems doesn't mean that YOU won't, but I also know plenty of people who shoot lead out of Glocks.
 
I was lucky and when I ordered my USP40 from CDNN, it was one of the early types with a normal land and groove barrel. Lots of aftermarket barrels are out there if you really want to shoot lead out of it, just make sure to add up the cost difference... :D
 
My standard practice load is a lead 165grn semi-wadcutter. I've shot at least several thousand of these in my usp40c. Just remember to always clean the barrel after a range session.

Don't shoot a FMJ through in an attempt to remove lead build up. H&K does say in the manual not to shoot lead, and they also state the uspc is built to withstand all +p and +p+ loads safely.

It is a great pistol and you seem to have gotten the much better end of the deal!

Congrats,

Never tried the h+P federal stuff, but I have shot a couple of boxes of Corbon 124gr +P through mine. Corbon is known for having some pretty hot stuff, so I'd suspect that the Federal stuff would be no problem at all.


I should have a review posted soon on my "new" Hk USP 9mm.

Fella's;

I've got an H&K with a polygonal barrel. I've come up with a solution to the lead bullet thing that works for me.

Rather than shoot a pure lead bullet, I buy the copper-washed lead. If you don't try to get wild with velocity, they work just fine. I duplicate the 980 fps with 180 gr bullets & have never missed a tick with it.

The copper-wash bullets are only slightly more expensive than pure lead. However, if you're committed to making it yourself at home, the start-up costs are going to be up there.

Oh, & the H&K is strong enough to handle the +P+ loads, they have a fully supported chamber. Unlike some mis-cegnated union of the Lego's GMBH & the Austrian military.

Witty, perhaps, but misleading--you should have stopped after "loads,". 9mm Glocks are rated to function with ammo up to 43,500psi--a good 5Kpsi above the pressure spec of the Federal load in question, and WELL into the +P+ range. And the chamber support issue is primarily related to 40S&W pistols, not the 9mms. Just because you don't like a firearm is no reason to spread misinformation about it.
H&K does say in the manual ... the uspc is built to withstand all ... +p+ loads safely.

It's not particularly relevant to this question since the 9BPLE is really just a top-end +P load (pressure is 38,500psi--in spite of the product labeling), but it's hard to believe that a gun company would put something that open-ended in a manual. I could go into business selling a 50Kpsi 9mm load tomorrow and stamp it +P+ given that there are no established upper limits for the +P+ designation. At that point H&K would either have to revise all their manuals and issue a statement or they would be forced to honor their warranties and pay damages since their manual says +P+ is safe in their pistols. My USP is older and not a compact--the manual only says that all SAAMI and NATO spec ammo is safe. NATO 9mm can fall into the lower end of the +P+ range, but that's still not nearly as open ended as saying that all +P+ loads are safe.
 
JohnKSa;

I'm sorry, I don't understand. Are you arguing that the H&K's don't have a fully supported chamber? Or, are you arguing that the H&K product literature doesn't say what usp_fan says it does?

What misinformation did I spread? Or - - is that your province?

Ok...

I have no doubt that the H&K Compact will handle the Federal +P+ load mentioned. I just find it interesting that a company would sign up to saying that their pistol would handle ANY +P+ loading given that there is no established upper pressure limit for +P+. Also, my H&K USP manual makes no statement whatsoever about +P+. I'm curious to know if the manual has changed.

The part of my post about misinformation was in reference to your misleading implication that the unsupported chamber in 9mm Glocks makes them unsafe for +P+.
 
JohnSKa;

But my brass coming out of my H&K doesn't have these funny little bulges near the case head.

900F
 
And the brass from your 9mm Glock does? Or are you just repeating what you've heard.
 
JohnSKa;

I don't own a 9mm Glock, didn't say I did. But that doesn't mean that I can't observe it.

My 9mm Glock 34 said the same thing (Factory approved to fire +P and +P+ rounds.)

Congrats on the purchase, an USP Expert in .45ACP is on my short list!

Saying that there's nothing preventing you from observing it is different from saying that you have.

Why don't you say you have--just go ahead and say it straight out. It's not like there's any way I can prove you wrong.

Unless you count the fact that I've been shooting 9mm Glocks for years and haven't ever noted any of mine bulging the brass.
