I have a Sten and a couple of M11/9's waiting in ATF jail. I also have a MasterPiece Arms Defender. I have Sten, Shockwave ZMags and Tepco magazines. Since all the magazines are similar and suffer with the same issue of being a pain to load, I'd like to get a magazine loader to help save my fingers. I don't mind paying for the best quality. What are my options?
