I have a HK UMP 45, it is the more expensive version not the competition version which retails for cheaper. I have a lipo battery and charger aswell as the hi cap mag and a foregrip on the gun. Played with it a a few times and it runs really well just lost interest in the sport. I believe the gun retails for around $275 and all the accessories I bought separately so I’m asking $225 but make me an offer and we can work something out.
