What pellets does it like ??
You can research the switched-out adjustment screw mod or the RC bearing mod if it's a standard Crosman trigger. Work at your own risk. How bad is the factory trigger? Does it seem like the typical Crosman variety with the blade safety and adjustment screw? The RC bearing mod is AWEsome IF and that's a big IF, it's safe in the gun. Switching to a longer adjustment screw can also help, also very dangerous if you screwit in too far. I have very nearly injured myself grievously on a couple of occasions messing with triggers this way. Be VERY VERY careful.
