It seems I was not the only one to have issues with AK magazines fitting my AK47/74s.
Switchpod did a review of what fit and didn’t fit his Palmetto State Armory GF3 AK-47 pistol. It looks like he had similar issues to what I was having to deal with.
I saw that PSA pistol at the SHOT Show and kind of fell in love with it. The GF3 AK-P pistol with the triangular folding stock is almost a clone of the AKU-74 except that it isn’t in 5.45×39 and it isn’t a NFA short barrel rifle. It probably is as close to a Krinkov as I’ll ever get without jumping through all the hoops.
While looking at that video, I came across one from Ian of Forgotten Weapons in which he discusses the history of the Russian AK47, AKM, and AK74 magazines in all their glory.
