I was looking for the picture on my computer but cannot find it. I had a picture of a older smith 10 that had a weird laser that dropped down off the side and below the cylinder that was mounted in the same general area on the sideplate. It had an odd mount with 4 screws but I cannot tell if it is the same type or not since I cannot find the picture.
Actually, there are 5 holes for concern .... why was the 5th hole drilled below the hammer (where the obvious screw is above and left of the 4 holes)? I imagine that is part of the whole process as well.
