Dan22: Sir; for others and perhaps yourself: Do not send your 'Old Model" Ruger 3screw back to Ruger for the ''update''

These are collector models

{I don't collect anything I don't shoot}
Ruger marks each with the up-dated #'s under the grip

'?What? does this obscure change mean???; To each his own
Ruger has in the past

Sent a Letter; The letter becomes part of the ''lore'' history to having a Ruger. ?Giving? it more value.
