Wonderful, just wonderful. I did that trigger mod to my piranha and now i shaved off about 2-3 mm off the original pull.
PIRANHA OWNERS: another simply way to do this mod is to find something small and thin to wedge between the frame and the sear release lever. Makd it so the sear release does not fully return to its original position. If it dosent cock you over did it.
You can also increase the diameter of the pin the sear rests on. Thats the little pin that is pretty much the sear release lever. Its all one piece. I just rolled up a strip of cardboard and super glued it on the pin.
