Got a paratrooper repeater with a very heavy trigger. I know the repeater bit wwont effect the weight of the trigger pull but wondered if this was the norm. I can't measure the actual weight it releases at but it feels like a carrier bag full of groceries cutting into your finger after a few shots. I'm guessing it's somewhere around 10-15 lb. So, appart from a trigger shoe is there much that can be done without risking ad?everything in there looks ok, its clean, no damage thats visible. Is it just the design of the mechanism or has someone got an idea on how to get down to half of what it is. Never had a go with one of these before so I don't have anything to compare it with. I can hone & polish but if it's not going to make much difference because of the design then there's not much point. Any ideas please? I understand the trigger weight isn't adjustable but pull length etc is, is this right?
