Has anyone tried the method of improving a Smith revolver trigger as shown on Utube by Larry Potterfield of MidwayUSA? It involves honing (polishing) sear and trigger surfaces with a fine India stone and I'm a little concerned that since these are case hardened parts that honing might cut away the hardened surface.
Also, anyone have experience with the spring replacement kits sold by midway for K,L,N frame Smiths? I've got a Mod 18 with the heaviest, worst, single and double action pull of any Smith revolver I've ever fired and I've got to do something to fix it. Thanks for your help.
