    Question Will this trigger fit my USP9 Fullsize?

    Like the title says, will this work in my USP9F?

    Since the complete kit says it fits the USP 9, 40, and 45 pistols, I would assume so.

    Well, Numrich does specifically label it '.45 ACP' AND they have a non-match full sized version that is labeled '40 & 9mm' as well as another non-match full sized labeled '.45 ACP' and these normal full sized triggers have different product numbers... So I'm going to say NOT a good idea to try and put the trigger labeled '45 ACP' into the gun labeled '9mm'.

    Then again, based on the above post and looking at the linked kit maybe it will work.
    But if you are looking for the full trigger job you might want to go ahead and pony up the coin to get the entire kit.

    Yes. They match trigger is the same across all models. Keep in mind that you will need the over travel screw to have any added benefit. HK USA does have that screw in stock as of a few weeks ago (I bought it direct from them). give them a call first!

    Yeah the only confusion on my part was because of Numrich’s specific wording of “.45 ACP”.

    I didn’t know if maybe there were legacy parts that were of different dimensions or something.

    Anyway thanks to all who posted, I grabbed the trigger the stop and a nickel flat spring.

    The rest of the match parts are unecessary as this is going in an LEM gun.
