Just picked up my Benelli M2 and my 2-Point Wilderness Sling. Only problem is the 1 1/4" won't fit into the 1" slot on the pistol grip and the sling swivel attached to the mag extension. It seems the 1" slot on the pistol grip and sling swivel is a design flaw considering most standard shotgun slings are 1 1/4". Comments and/or suggestions please.
