Its definitely doable. I have personally put some 91mm Vic Scissors onto mine:(Image removed from quote.)I used a Dremel tool to widen the stock pivot hole, and although I dont have a pic, the scissors did over rotate out, and did not snap into place.I want to say ThePeacent put Wave scissors into a Power Plier (PPPs older brother, with the same retention method and pivot size), which should be a drop in mod. SOG scissors (available for purchase online) may work despite SOG saying otherwise, but they aren't very good, so I would avoid them.

So for the basic unskilled, not mechanically inclined, person such as me, if I just want drop in, then scissors from a Wave will work it seems.Appreciate the replies!
