When I got my old USP compact from KWA I had this exact problem. It fired like 7 rounds before the mag ran out of gas, no leaks, no problems with the gun. I brought it in to my local AONW, and they just lubed the mag, no payment neccessary, After that, It shot like 30 rounds before running out of gas. So try lubricating the magazine and gun. Hope I helped
