Abstract
A cartridge follower for pushing against cartridges in a tubular magazine of a shotgun. A front face of the follower has at least one forwardly protruding member offset from the center of the front face to be tactilely distinguished from a cartridge in the magazine, but which cannot contact a central primer of a backwards cartridge. A method for determining whether a shotgun is empty includes providing such a follower in the magazine, inserting a finger into the outfeed end of a magazine, and attempting to feel the protruding member.

A cartridge follower for a tubular magazine for a firearm, comprising:
- (a) a body having a lateral peripheral surface, a rear end adapted to be engaged by a follower spring, and a generally circular front face, said front face having a center portion and defining a base plane;
- (b) at least one forwardly protruding member located on said front face and having a height relative to said base plane sufficient for said protruding member to be readily discernable by touch;
- and
- (c) said center portion of said front face being free of protruding members.
A cartridge follower for a tubular magazine for a firearm, comprising:
- (a) a body having a lateral peripheral surface, a rear end adapted to be engaged by a follower spring, and a front face, said front face having a center portion and defining a base plane;
- (b) a plurality of forwardly protruding members located on said front face at least one of said protruding members having a height relative to said base plane sufficient for said at least one of said protruding members to be readily discernable by touch;
- and
- (c) said height of any protruding member located in said center portion being no greater than said height of any other of said plurality of protruding members.
A method for determining whether a tubular magazine for a firearm is empty, comprising:
- (a) providing, within a tubular magazine for a firearm, a cartridge follower including:
- (i) a body having a lateral peripheral surface, a rear end adapted to be engaged by a follower spring, and a front face, said front face having a center portion and defining a base plane;
- (ii) at least one forwardly protruding member located on said front face and having a height relative to said base plane sufficient for said protruding member to be readily discernable by touch;
- and
- (iii) said center portion of said front face being free of protruding members;
- and
- (b) inserting a finger into an outfeed end of said magazine and attempting to feel said at least one protruding member of said follower and determining by feeling said protruding member that said magazine is empty and by failing to feel said protruding member determining that said magazine should be considered not to be empty.
In combination with a tubular magazine for a firearm, a follower comprising:
- (a) a body having a lateral peripheral surface, a rear end adapted to be engaged by a follower spring, and a generally circular front face, said front face having a center portion and defining a base plane;
- (b) at least one forwardly protruding member located on said front face and having a height relative to said base plane sufficient for said protruding member to be readily discernable by touch;
- and
- (c) said center portion of said front face being free of protruding members.
