thet's why marstar sells 20/5 mags- to give you something to grip when you're changing mags- it wasn't designed for those 5 round mags- we used to call them "parade mags" in the old days- specifically designed so that your had won't catch on the mag when doing one of the "arms" : present arms, shoulder arms, whatever- can't remember which one it was- didn't have that problem with the fnc1 for some reason-Polar Man said:
the only other reason was so that the conservation officer didn't stick you with a charge of having more than 5 rounds in the gun while hunting- a hunting reg, not a mag limit- at best they're a legal thing, at worst they're just plain inconvient
