here is my new SP-01 tactical with my older SP-01 safety. The tactical has been cajunized before even being chambered for the first time. CGW for the win. Mods included 13# hammer spring, race hammer, hammer pins, trigger return spring, modified firing pin block lifter, type 2 disconnector, firing pin, firing pin spring, firing block spring and all the other pins/springs that you can change out. Anyway, the trigger is awesome sweet now. Just waiting for a couple of more parts before the SP-01 saftey gets converted to SAO. I have a feeling the twins are going to be my all time favorites.
