I suppose both Ken and have "jaundiced" opinions since we both make money by "upgrading". However what is the difference between Ken working in his home/shop or the Colt work shop? Several of the "subcontractors" do much better work than the factory folks. Finally a worn field grade that is restored/upgraded with shootable demensions and nice engraving will serve the owner and/or his-her heirs for years to come. That's my $00.02 worth, Best, Dr. BILL
