Aim has USP and USPc pats kits for 39.95 plus tax and shipping. If you are a new customer and sign up for emails they give you 10.00 off. The kits are from LEO trade ins. No Frames or Barrels. Hell Hk wants 70.00 for a recoil spring guide. https://www.aimsurplus.com/products/leo-trade-in-hk-usp-full-size-40-sw-pistol-parts-kit https://www.aimsurplus.com/products/leo-trade-in-hk-usp-compact-40-sw-pistol-parts-kit |

I bought 2 kits a Full size and a Compact. The parts showed some wear but all are very usable. The parts were dirty like they just took apart the guns and threw the parts in a baggie. The Full size kit was worse, but everything cleaned up nice. My Compact kit was missing the trigger. I contacted Aim and the quickly are sending me one. I see some USP parts are discontinued and I shoot both of mine. I had a problem with the recoil guide in my Compact. The little C clip kept coming off. They are 5.00 apiece plus tax and shipping. You can shoot it without the clip ,but I didn't like that. I contacted HK. They wanted 70.00 plus shipping for the new style guide and spring. Finally, after calling every so often a tec sent me one. The kit has the new style guide rod and spring. I also saw on Midwest gun parts that the extractor was dis continued. That was what made me buy the kits. I am glad they will work for you. |

Got my parts this yesterday. I'm really happy with them. This is looking like a big win for me. The full size parts kit is very dirty and has a little surface rust. But not a lot and very little wear from what I can see. The compact parts kit is in very nice condition. No apparent rust and not very dirty. I don't see any obvious wear either. I just ordered another one of these. Both parts kits appear to be LEM. That's a real bonus for me since I was going to buy two $85 LEM conversions for a USPC 9mm and USP Expert 45. Now all I have left to buy is the GG short reset kit. (hopefully GG will have a 4th of July sale).  I also have three spare stripped slides inbound. Two compacts and a full size. So now I should have at least most of the parts needed to complete them. I plan to buy threaded barrels and send them out to get milled for a red dot. That way my original slides stay unmolested and I can swap back and forth between the basic iron sighted and RDS equipped slides. I soaked the parts overnight in mineral spirits and brushed them off with an old toothbrush. I have them soaking now in Breakfree CLP. Then I'll give them another brushing and give them a closer inspection tomorrow. |
| Both my kits are in good condition. Funny my Full size kit was pretty filthy also. It cleaned up nice. My Compact kit was missing the trigger. I contacted AIM. They asked for a pic of all the parts in the kit. Sent me a trigger immediately. When you look at what HK parts go for the kits are no brainers. I am very happy. |

(which makes sense since these are apparently LEO trade-in parts) BTW, since you now have the parts to complete them (except the barrel), Atlantic has stripped USP9 Compact slides for $220 each: https://atlanticfirearms.com/hk-usp-compact-s9mm-stripped-slide I just got two from Moka's Raifus (He's sold out now) and they are beautiful, brand new with no msimatched external serial numbers (the slide's SN is marked inside the slide on these). Perfect for an optic cut while keeping your original slide intact. |
