I saw something similar in secrets mag, I thought it was a good upgrade. So what I did was drill thru the existing bore to the outside where the plunger and spring sits. Then tap the hole 3/4 fine. I used 3/4 all thread rod 1 3/4" long with a jam nut, in a lathe I faced off both ends of the rod and cut a screw driver slot in one end. It eliminates the plunger and spring. When installed, I ran the screw in then backed off 1/8 of a turn.
