i did not intend that as a, uh... attack or insult. i am purely curious at how they do. crow mags do expand big and fast... more curiosity than anything. if something comes my way, in the shape of a bandit, groundhog, or country rat, it will eat a pred to the dome... and nothing more... however with that said... minus the red polymer tip.... which pulls out quite easily... a crow mag, and a polymag, look nearly identical....
