The grip thread screw size is 1/4-28 and the length seems to vary with the manufacturer. I recently purchased a grip screw with and internal adjustable set screw which when adjusted correctly all but eliminates the extra travel associated with the cheap triggers. So my question is this... could one simply go to the hardware store and purchase a longer 1/4-28 screw and either cut it down or shim it in order to do the same function as one of those special $15 screws?Attachment 157122
