ok guys, so I pulled out my old sigma out of the safe the other day and decided it would be fun to do a trigger job on it. well one of the last things I ever did was put in a wolf guide rod and striker spring before I put it away. oh and by the way its a model sw9ve and the more and more reading I do. I found my self doubting myself on using the wolf striker spring and guide rod. This is where I need the experts to help me I really cant remember if I did use the wolf striker spring or not so when I pulled out my factory guide rod. I cant tell the striker wolf spring from the factory spring apart the only difference is one of the springs are grinded flat on both ends and the other one is not I have a feeling that the grinded one is a factory striker spring and the one that isn't is the wolf one. Could someone please help
