Surefire. I've got one of theirs on my black collapsible Mossberg 500 and it's tough. Bright too. The beam is non-adjustable so I thought it might suck at a distance but it's clear to probably 30yds and has pointed out distant night animals at a good 50yds. It's been duck hunting, lived in a truck bed, tied to the front rack of a quad, gone swimming, etc. etc. and aside from batteries it just keeps going.
I like your gun and desperately need one.
