I work at a shooting range in Texas I asked several gunsmith about the trigger mod and all said the same thing not to mess with it lol. I know a lot of us have done the trigger mod but not many post how they function after words. I have a 40 s&w i decided not to listen to the gunsmith and since no one work on the sigmas I replaced the striker spring with a wolf 3 1/2lb, I removed the tail spring, and left the other two springs as they were i have shot about 500 rounds and it works great. I would like to find a replacement spring instead of just removing it. If any of u have tried it with one spring please e-mail me let me know how it works one of my friends said his trigger was not reseting with only one spring.
antonio.dehoyo@yahoo.com please let me know and if you know where to buy a repalcement spring (lighter spring for the outter let me know) thanx
