My aunt has a Mossberg 500 Tactical Cruiser with the breacher muzzle break. I want to get her some accessories for Xmas. She has mentioned wanting a sling, but she didn't think the ones at the gun show fit a woman well. Anyone have any idea of a good sling for that particular pistol grip shotgun? What other quality accessories do you recommend that are under $50? Thanks and... Merry Christmas!
