Something has changed...
I have these type of mags for a while - work fine and no problem. these new one are a bit different - the top plate is a half millimeter wider. for the VFC gun it is not a problem, but for the loader (I use something similar to Odin Innovations M12 Sidewinder Speed Loader) it is a problem. I can force it in, but when I try to pull it out - I managed to brake one... My 3 new mags are "one the shelf" till I figure out, how to fix this. Probably will try to sand off the overlapping sides...
