Here is a quick tutorial on how to replace the safety spring on an AGD Automag frame. I recommend a shorter spring for this style frame since the allen screw takes up some of the space in the hole. Later style sheridan frames also use a shorter spring because they also use an allen screw.
This same procedure works to replace the trigger safety spring in a Sheridan frame but the Sheridan frame lacks a set screw to hold the spring in so you will need a slightly longer spring.
