I don't have a lot of experience with Saigas, but do with guns in general. I have only shot AGP mags through a Tromix S12, it was flawless. 9 rounds, 3 seconds. Would've been all 10, but I lost count.. I have 2 AGP 10rd mags I built myself. I've loaded them, and they unload smooth and quick by hand. Good fit in my S12. I look forward to breaking in my brand new S12 with the AGPs.. As you all know, good mags are ESSENTIAL to have your firearm work properly, I think AGP does the job.
