Advice needed on USP double action trigger pull

Hi gang,
Got a question for you HK USP owners out there. I have a relatively new USP.45 fullsize. The double action trigger pull, while tolerable in weight and length, feels "sticky" for lack of a better word. IOW, while pulling back instead of "gliding" like a Sig DA, it kinda bumps along as like rubbing your fingers over a vinyl car seat on a hot day. (creative explanation, huh? :)) Anyway, is there a spot I should lube in particular (using BreakFree) to smooth it out? I can't really see any good lube points for trigger / trigger bar assembly travel. Thanks for all the help!

I have a USP9. The trigger improves somewhat with use. I have found that a little grease (I use Shooter's Choice) at the contact points helps. If you really dislike the trigger, the match trigger kit is about $100.

HK USP triggers tend to smooth out after the initial break in period....say 100,000 rounds or so. You can speed that up by dry firing a few thousand times a day (If you don't already). I've found that turning on the TV set helps when your hands get tired. Video taping C-SPAN so you can "freeze frame" your favorite character is also a neat trick. If after 120,000 rounds "ish" or so the trigger is still rough, I would try a different USP to compare...maybe you've got a lemon?!? ;)
Regards,

I dry fire the hell out of my USP and I guess that's why everyone I hand it to comments on how great the trigger feels. Once it broke in, I haven't found a pistol I like better.

Airborne is on the right track ;) My USP DA trigger was, how you say? not so hot at first. I do dry fire...not quite at the rate suggested previously...and shoot the thing quite a bit, and the trigger has smoothed up considerably. As far as what specific nubbin to hit with the CLP, I'm not sure.

I used to own a USP9F.
One thing that I think made the DA pull better was the following:
With the hammer down, there's a small hole visible beneath it (looking from at the rear of the gun). A drop of lube placed strategically in that hole should make the DA pull somewhat better.
My apologies for the crappy description , but I no longer have a USP at hand :(

Good luck!
 
I agree that use makes the HK trigger better. I also dry-fire the heck out of mine. Another thing that I did was to put my thumb lightly on the hammer, not allowing it to fall, and pulled the trigger slowly back over and over. I don't know how good of an idea that is long-term, but you can just feel the parts smoothing out.

Also...I asked my local gunshop about the HK match trigger, and they told me that they couldn't be gotten individually, only with the HK Tactical!

If this is not true, where can I find the match trigger for $100?

Dry firing with snap caps that is, the USP (esp. 45s) has been known to break if dry fired excessively without them.
 
Actually, the match trigger is the way to go, they cost about 130 Swiss Francs over here and CAN be bought. In fact, my dealer has a few in stock.

Else, try what PeterVN wrote.
 
Dang, I wish y'all woud quit talkin' 'bout USP's. A USP was the next gun on my wish list and now that we are building a house it will have to go on the back burner.....the far back burner. :( Now is it just me or does it seem like every other post in HG&PC is about USP's? :D

I can personally vouch for Cal's Armory - I've purchased many items, including a few USPs (sorry, Gunslinger!) from them.
 
With a name like GlockTiger you ask about H&K? Mine was horrible too. Thought it was on some sort of ratchet for awhile. Got rid of it before it ever smoothed out. Couldn't afford the 100,000 rounds needed to smooth it out. Did try to have a 'smith work on it. Only thing he did was loose a tiny part that it took 4 weeks to get a replacement for. Good luck. Their pretty accurate. If you have a variant 1, carry it cocked and locked. You'll like it alot better that way!!!

The stock trigger will smooth out but the match trigger is really a gem.
Maybe it is a question about leverage,
You can try placing your finger at the very bottom of the trigger where it curves and "pull" straight back.
Squeezing don't seem to work as well with HK triggers.
 
Well, Danny45, Glocks were (and are) my first love. I still believe them superior as an all-around combat weapon. However, I've come to appreciate the virtues of other modern designs, and I enjoy my HK and Sig very much. I solved much of the trigger pull issue by detail stripping and cleaning the factory gunk off of the sear/hammer/strut/etc. and re-lubing. It's back to normal now and breaking in ok.

Truly, though, despite it's "stickiness," I'm surprisingly good with it in DA mode, able to draw from a thumb break holster and quickly fire a five-shot string at 10 yds keeping a 3-4 inch group. Which is good for me.

You might want to try spraying a quick blast of Hoppe's Dri-Lube with Teflon in that small hole in the base of the hammer. I also spray the trigger mechanism and the safety. When you dry fire it you'll notice an immediate change in both DA and SA trigger pulls. The trigger should glide much more smoothly. And if you decide to get the Match trigger it will feel like a whole new gun :cool:.
