Ok i have a ruger superbackhawk new model put a wolf spring kit in it now if i tighten the frame screw (pivot locking pin) it locks thr hammer and trigger back it out and it works ok if you dont pull the hammer back fast if you do the cylinder doesnt lockup and it wont firer i ordered a new pivot pin thinking the old one is bent or out of specs i also think the wolf hammer spring is weak why it doesnt lock or latch when hammer is pulled back fast any help is welcome . Thank you in advance
