The problem is that real UPM mags hold 25-rounds.. I made some blocks to take them down to 10, but mostly I shoot them out of state.
In CA you're best bet are USC single-stack 10-rnd mags which work even in UMP lowers (although they wobble so hit them against anything while shooting).

Thanks so much for response. I checked HK parts but they are out stock . HPSP has them but he only sells complete lower conversion kit . Are you in OC?
