Here is an old school Automag sear return spring modification which I haven’t seen in a while. Spring on the back of the sear hinge to pull the sear forward.
I would imagine this helps with pressure problems (low tank?) where your on off pin might not reset all the way? If I’m wrong correct me.
I remember my friends had this mod on there mags in the late 90s.
This came on an Automag from a Santa Cruz area (Watsonville) player named Joe, who played on the Wizards.
“[I] Played for the Wizards [out of] pajaro river, [and] phychotic sixth division [from the] same area. [We] won [the] USA championship [in] 1993-94.
[I also] played in [the] Big Game in Corona [in] 1990, 1991,1992 [and] 1993.”
