I just got this model 19-3 that has very few rounds through it. Inside and out it shows very little wear , I wouldn't even call it wear. Shoots tight groups. What puzzles me are the stampings in the grip frame. An L in a triangle and an R in a circle on one side and a large 3 with a c, 9, 1 and 7 randomly placed on the left side as well as a symbol that looks like two crossed golf clubs and 7 little tear drop shaped marks by the crossed - whatever. Can anyone offer what all this indicates? I just find it peculiar for all of this to be on a revolver that has seen less tha 100 rounds. Thanks for any help.
