Just picked up a Smith model 60 chief special no dash .38 special.Nice gun only thing I'm not super happy with is the serrated trigger.The hammer and trigger are silver but dont look stainless like the rest of the gun.I was wondering if it is some kind of coating as I'm thinking about taking emery cloth to it to knock down some of the sharp edges.SN is 626xxx was also wondering when it was made.Any info is appreciated.
