I'm pretty sure it was the new mag full of preservative grease. I cleaned it out and now the spring depresses properly. I picked up 2 Metalform 7 round SS welded base magazines today with the round follower. They fit and drop out okay and lock the slide back properly.
Curious, what's the difference between the flat USGI style follower and the round followers? One for FMJ and the other for HP bullets?
Also, what's the big difference on welded base plates vs other types? And are the bumpers that screw in on the bottom worth it?
