The factory VERSA MAX® trigger group pin is only held in place by a small detent spring that can fail under recoil or can easily be lost while performing maintenance or modification. The XS® product is a headed pin retained by a 6-32 pan head screw, acting as a mechanical lock keeping the pin in place. Any serious hunter, competitor, or law enforcement officer can now upgrade his/her VERSA MAX® to experience the upmost reliability and durability from their shotgun. This pin will also fit the Benelli M1, M2, and Super Black Eagle 12 gauge shotguns, as well as the Stoeger M3000 and M3K.
