I bought a used stainless steel Encore barrel that had sights but were taken off. I need a 8-40 ss plug screw to fill the front sight hole. I called S&W and they sent a screw but it won't work. They sent a two pack of 8-40x.125 and the .125 is too long for the hole. The threads were correct, but the length is off (yes, the bottom of the hole is cleaned out...it's just too long of a plug screw). Does anyone have a shorter ss plug screw they can sell? I really don't want to buy a dozen to get just one. Anyone got one shorter than the .125" one I got? Thanks
