Doug,
I use grip adapters on all my revolvers that do not have the target/combat-style oversized grips. I have used Pachmayr, Tyler-T and just bought an old Merchon grip adapter I saw on eBay for my Colt Army Special. Tyler-T is sort of still in business, but the factory was damaged by a tornado in the recent past and they are slow to no-go on filling orders from what I hear. An outfit called B.K. Grips makes a Tyler-tyle grip adapter out of plastic, but he's only doing them for S&W revolvers at present. I tried looking for them at gun shows, where they usta be a dime-a-dozen, but no more! Amazon, eBay, Gun Broker, etc,. is now the place to look and most go for about $25.00.
