Gunsmith used USP parts on my HK45 for V3

[Jeff Gilbertson]

Is this kosher? I wasn't even aware of it when I first picked it up. I took it to the range, and it worked just fine. No issues whatsoever.

Upon arriving home, I looked at the (now) decock-only lever and realized it was from a USP. I still have my original parts. Other thing I noticed is that, unlike my USP .45 Tactical, upon decocking the hammer, the lever doesn't quite go to the full up position on its own. It sort of stops about 10 degrees from horizontal. I can then manually move it up fully, and it will stay horizontal after that, but it will not move up fully horizontal by itself, again unlike my USP which I also had converted to V3 several years ago.

I'm guessing this isn't the recommended/approved way to get a V3 setup on an HK45.

Can I have him use my HK45 lever with the V3 detent piece?

Please advise before I go all postal on his (and my buddy's for recommending him) a$$.

Thanks,
Jeff

Ummm, I don't know about this... Personally, I'd be irratated if it was mine. I consider the newer control lever to be one of the major imporvements on the HK45, as I never really cared for the lever on the USP... I'm not aware of a varient three option available for the HK45 yet, hell even the LEM and light LEM are hard to find right now. I'm not surprised the USP parts fit, although probably not 100% which would explain the lever not returning to horizontal, since the trigger mech/fire controls are taken directly from the USP line. I'm not an HK smith, but I don't think the HK45 lever will work with a USP detent plate?

I'd contact HK customer service and see what they have to say?

I wouldn't accept it. Something is so obviously wrong with your dropped decock / safety control. If he couldn't do it right, he shouldn't have done it.

Well, I called HK USA today, Wednesday. The gentleman I spoke to (forgot to ask for his name) said using USP fire control parts on an HK45 is not authorized. He also said he has no idea when V3 parts for the HK45 will be coming in.

Looks like I'll be sending it back to the gunsmith to have the original parts re-installed and get my $ back.

Sigh.

Thanks for the help.
