If the spring is installed wind correct, then legs on top of the pin and one of the legs in the groove, and still the pin slipping out, it could be that the groove is too narrow and shallow for the spring leg. If that is the case, then just drill spin the pin while using a small file to deepen and widen the side groove in the pin.
Note: both hammer and trigger pins are the same. The hammer uses the center groove for the hammer J spring, while the trigger uses the side groove for one of the hammer spring legs to seat in it.
The Spikes LPKs I just installed all had separate trigger and hammer pins. Never seen it before, but they do exist.
