I have had these pistols since the late 1960s. I thought it was about time to dress them up a little, so I ordered some walnut grips in the WWI pattern made by Colt from Midway USA.
Here I have one set installed so you can see the difference.
Here they both are wearing the new grips. I thought of changing the grip screws but to my reasoning, new screws would take away from the character of these fine pistols.
