I really don't do anything to the triggers on my guns . I just break some of the sharp edges on the trigger parts , like a (ten-cent job) vs the (25 cent job) .
After about 500-1000 rounds , the trigger is just the way I like it .
Fact is , if it makes you smile , how could it ever be wrong..! I get a delayed smile , something to look forward to..!
Be safe and shoot away......!
PS: sometimes , removing to much material during the polishing can create some weird problems..!
