Gun is stuck except for wolff guide rod and all wolff springs. This is on a 21sf and is my ccw gun which i also shoot uspsa with for practice 3 times a month. I was going to change the recoil spring at 3k rounds but last match i was at 2700 and had some failures which never happened before. Went to the truck and put new recoil/striker springs in and was back in buisness. The gun has not been passing the 12'oclock spring test for a while so now my idea is to change springs at 2k rounds. I plan on changing all but the mag catch straight wire spring but want to know if that is crazy. I am not concerned about the cost savings since its minimal savings when trying to pinch more rounds from the springs. To change the entire guns springs cost $20 and 2k rounds will last me about 4 months so it doesnt matter much what i wpould save. My concern are the springs like the trigger spring and slide lock spring which will disable the gun if they fail. Being this is my ccw gun what do you guys think? Thoughts?
