depending on how much your willing to spend you can get some very nice adjustable triggers or even the entire trigger group exchanged. parker hale had made one of the best triggers for enfields but they are now out of production. the very best ive yet to try is the Knolton precision drop in trigger. it uses a double ball bearing contact face and both bearings adjust to shorten both the first and second stage independently. but alas the knolton is also nearly out of production so you will be looking at a $150 price tag for just the drop in version. the next best thing might be a huber concept trigger but it lacks the independent adjustments and the ball bearings dont actually roll on the huber.
