How can you tell what kind of trigger an H&K has?

Hello all,
Saw a H&K USP 9mm at my lgs and that DA trigger pull was brutal. Which one is the desired trigger on it and how can you tell which one it has?
Regards

I never knew HK was in the parcel business and related to UPS .

As for the USP, not sure what you mean by:

There are variants of LEM and DA/SA. If it had a decocker functionality, then it was DA/SA and you get what you saw. There are things that can be done to lighten it. Without knowing your complaint other than it was "brutal", not sure how to help. Sadly the P-series pistols, while smoother, actually have longer trigger pulls and a longer reset. Suffice it to say if your goal is a sweet trigger, HK is probably not your best bet unless you get some work done on it. There are some things you can do yourself.

The USP usually comes with either the DA/SA or one of several LEM trigger modes. The pistol you looked at probably had HK's standard DA/SA trigger, as the LEM has only one stage of pull, not two. The DA pull is about 12# and the SA pull is about 5#. The USP may also have a Match trigger, seen in certain USP models, but more than likely wasn't on the pistol you fondled.

If the shop has the correct box with the pistol, the label may help in determining exactly which of the many available models the USP is.

You can get a match trigger kit from hkparts.net or top gun supply. The USP Expert comes with it as well as an ambi safety.

I also like the light LEM trigger.

Match triggers can also be installed by sending the pistol to HK.

What you probably were experiencing was a Lem trigger that had been decocked.

When you decock a LEM trigger (dry fire without cycling the slide), you get a pretty insanely heavy trigger pull. This is the true DA pull that is actually compressing the hammer spring.

If you pre-cock it, as it would be when live firing, you would get a much less objectionable DA-ish pull.

That sounds pretty much like what I experienced. I have always wanted an H&K either USP or P2000 but when I dry fired it, it was very very heavy. I will make sure to cycle the slide when I look at it later on today.

By the way, sorry for the UPS instead of the USP. Very different things.

Regards to all.

Lol, don't be, I was just pulling your chain.

A LEM trigger that hasn't been "cocked" by the cycling of the slide is super heavy because you're working against a 14 lb hammer spring.

TunnelRat,
I was actually laughing myself when you brought it to my attention.

I remember the early days when H&K was getting ready to move beyond the complex and peculiar P7, and the USP was in the works.

The official corporate designation for the USP is "Universale Selbstladepistole" or "universal self-loading pistol". I have seen an English version as "Universal Service Pistol". But in the developmental phase, it was widely considered to stand for "United States Pistol." A gun they could sell more of to gullible Americans.

I just bought a couple HKs with DA/SA trigger. Yes the DA pull is heavy but I knew that up front. For me it is OK and I can shoot plenty good in DA mode at self defense distances and farther. However I was pleasantly surprised at the nice crisp SA trigger on both with NO hint of creep or grit - very nice.
