HKP HK UMP .45 - Magazine Compliance Kit

US-Made UMP .45 Compliant Magazine Kit For All UMP .45 Magazines

This kit is a drop-in replacement set that will give you two US-compliant parts toward the 922R rules and regulations. It's made from high-impact polymer, just like the factory HK parts. The US parts kit contains the mag follower, spring retainer, and floorplate. Fits all US-made and German-made UMP .45 mags

Please note: The floorplate is the same on all the UMP 45, 40, and 9mm mags, so you can use the US floorplate to get one US-made compliant part for your UMP 40 and UMP 9mm mags.
