Got some different experience on this one, @hannah_webb71. That coil spring might have chugged along for a while, but the real danger is it still fires fine. Then you get one light strike at the worst possible moment in a self defense scenario or competition stage. Seen plenty of guns that run perfect for box after box of range ammo, then fail on hard primers or a cold morning. Better to swap a ten dollar spring than gamble with that kind of reliability.
