Yep, even the last year of the 24 inch 1894 CB 45 Colt had smooth stocks. Still can't find my 2002 catalog but the 2003 catalog shows both the 336 CB 38-55 and 1894 CB 45 24 inch with smooth wood. That year the 357 and 44 went to 20 inch barrels and smooth wood. I did see a 24 inch 44 on GB while back with smooth wood so 2002 could have been the first year for smooth. I agree about the checkering on the 1894 CB's. Seems they used better wood and it fit better. I have yet to hold a 20 inch CB with smooth wood that suited me. I like those loooong 24 inch octagon barrels.
I like the checkered wood. Then again I like smooth wood too.

None of them feel any better than my 1895 CB's with smooth wood.
Still waiting on the 44 Sporter.

I hope it hurries along as deer season opens next Saturday and I would like to break it in right. May use the 44-40. It is at my dealers now. Got my eye on a big old buck or two here on the farm. I usually don't shoot the big ones but they have been taunting me all fall so far.
