Heckler & Koch Full Metal USP Compact NS2 Airsoft Gas Blowback Gun by KWA

"I have the KWA/Umarex USP Compact NS2, It worked as advertised for first few mags. The slide now binds up all the time. It has been cleaned and lubricated multiple times. After full charge mag, it won't fully cycle after 10th round. Tried another mag, same thing. I wouldn't buy another one. Going to look for something better.
