HK USP .40

[kawika]

The 9mm tactical has a stock trigger-no overtravel stop. The Tactical, Match, Expert, Custom sport and elite all come with the match trigger.

So I now have my HK USP in 9mm with HK tritium sights and match trigger.

The gunsmith said the trigger was wicked - he was right. Pull is about 3.5 pounds, and as crisp as anything I've ever owned.

But it seems that gun Nirvana is not so easily achieved.

I put snap-caps in, then put the weapon in condition 3. I pulled the trigger, the hammer snapped...but the trigger did not go into position for a double-action pull. It simply hung. A gentle touch with a finger resulted in it going forward. This seemed to happen consistently.

I put a drop of militec oil on the exposed parts of the trigger (I did not field-strip the firearm), and the hanging went down to 2/3 of the time.

The weapon is hardly fired - perhaps only a round or two by the gunsmith who installed the match trigger.

I called H&K - they suggested a trigger installation problem.

So...should I visit the gunsmith for an adjustment? Shoot a few hundred rounds through it first? None of the above?

Any thoughts and suggestions appreciated!

Thanks...

HK hammers normally sit a bit loose and backed off from the strike cap. Is the trigger resetting after you pull the trigger and letting you pull it back in DA?

If not, you might need to ask your smith to check his work for burrs, rough spots, or a spot where the tolerances were set too tight.
