Doing a quick magdump with the new Magpul D-50 for the HK MP5/HK94/SPS drum. holds 50 rounds and works flawlessly so far. I had to shave about 1/8th of an inch off the vertical grip to ensure it didn't contact the drum. before I cut it, it rubbed against the drum but the drum still inserted, don't know that would cause a malfunction but better safe than sorry.
