Tango Down/Vickers Tactical magazine floorplates amongst the crap on my gun cleaning table and figured I'd stick one of them on the G37's magazine, just because.
I have never seen a Glock floorplate so difficult to wrestle off the mag tube. I failed, and handed it over to my co-workers. I think it was the third contestant who finally beat it off the mag body by main force, possibly with the aid of a hammer. And then the new floorplate wouldn't go on because I didn't have a c-clamp handy.
The score so far is Glock:1, Me:0. I'll not be defeated so easily, however...
