I did a complete breakdown on my relatively new GP 100 last night and upon reassembly noticed that the trigger pull seemed to be harder than it was when I first got the gun. After inspecting things over to make sure everything was back together properly it looks like the plunger for the trigger assembly no longer sticks out quite as far. Does this mean perhaps the spring within the trigger may be more compressed leading to what I feel is a tougher pull in double action. You'll have to forgive me if I sound like an idiot, as handguns are still relatively new to me. Thanks in advance!
