Does someone know how to remove the grips from a TLA flattop target? since they are not held by the usual visible screws that most single actions have, I am not sure how they are held onto the grip frame. I am tempted to remove the screw from the bottom of the grip frame but I would like to know what it does before I start disassembly. I have not seen any specific disassembly instructions for this gun but I assume it is like most single actions except for the grips. I would appreciate some thoughts from those of you that have disassembled one of Grover's guns.
