12 gauge Spring & No Jam Follower Kit. Specifically designed for the Beretta 1301/ A300 Patrol.

Replacement shotgun magazine spring and S&J Hardware No-Jam Type 3B magazine follower. Magazine spring is 48 inches long.
Spring is extra long, so it will probably need to be trimmed to size.

Our spring is made from Chrome silicon wire is one of the most desirable materials for manufacturing springs. Chrome silicon wire has high tensile strength and unmatched resilience when it comes to high temperatures. This kind of wire is heat-treated and cold drawn. 1 million cycle spring.

Our no-jam follower is the best on the market today, will not break down with cleaning compound and will not crack. CNC milled from 2 inch block of DuPont Delrin®, it does not react to heat or cold, and thus reduces jamming.
