it is a must upgrade
now i have seen these triggers go from about 25 bucks to now 40 bucks and i wonder if they will just disappear all together and if that were the case now is the time if you have thought about buying one
we have all thought about buy this or that and waited only to find out there are none to be found been there done that
and remember the factory screw is tight use a good quality screwdriver that fits well
