Product did not fit firearm. Part received, Navy Style SEF housing for MP5K, did not fit upon receipt. Had to purchase metal hand files and spend a couple of hours hand fitting the housing to my weapon. There was no mention of this being required in the product listing and after doing some research I am far from the only person to have this issue. Despite poor fit, product arrived in good shape and appears high quality.

That I could buy a P7 trigger return… That I could buy a P7 trigger return spring 'for a platform that HK no longer supports'. The P7 is the finest 9mm pistol. It needs no 'tuning', just lube & proper bullets. If I had unlimited funds, I'd commission Proof Research to make a Titanium frame, to learn if some weight reduction could improve the design.

Great selection of parts Great selection of parts, most of which are in stock, and speedy shipping through the postal system, which I prefer! Continue the great work, and keep keeping the HK fan club happy!

Happy return customer I am a occasional shopper and buyer. I purchased extended selectors for my SP5K. Also purchased a magazine package. Two 30 round mags with HK coupler. Very happy with all items purchased. Hk parts shipped fast.

Hk parts almost always has what I am… Hk parts almost always has what I am looking for in stock (with the exception of a P30 firing pin) and at competitive prices. They ship quickly, and all of my orders so far have been 100% accurate.
