I have a WASR GP-10. I bought a dozen mags from Sportsmans guide. I loaded them, but I just realised I better check to make sure they all fit ok. Some are almost too loose. Where as others are too tight to fit in the mag hole. The front part of the magazine, where it pivots at, is too large to fit in the hole. Is this normal? My AK came with those 4 spots preground, so I didn't think I'd have any problems.
