I have a M19 that I've carried around the homestead for several years and it gets the same loving care. It lives a harder life than my pocket gun because I carry it in a belt holster so it's more exposed to the elements. It really looks bad when the holster is full of saw dust and wood chips. Blow it off and it keeps on shooting. Larry
