... Besides the "looks cool" factor.

Easier to shoot?

Harder to shoot?

Best for people with only three fingers?

The birdshead grip doesn't suit my style of shooting, nor does the round butt of a Smith.

I find that the flare of the grip aids me in supporting the gun's weight much better and provides me with a steadier hold.

The advantage I've found to the rounded butt is that it does conceal better under a coat or vest, not "printing" as does a squared off butt.

I've found that without the support of the flared backstrap, I tend to point low in getting off fast shots. My preference has been the Super Blackhawk grip for deliberate, two-hand shots, and the Blackhawk (not the older Colt style) grip better for duellest style shooting.

This my preferences. You may discover differently.

Is the one you found like this one except in .357/.38? This one is a hoot to shoot, short barrel and all!
By the way, the best feeling grip (to me) I've ever found in a single action is the Bisley, hands down!

Doc Holiday put Johnny Ringo down with one. (Tombstone) WM you got to have one as they are so cool. I can't beleive that Ruger quit making them. You never see them around here.

I had a birdshead Vaquero in .45C when they first came out and traded it off. Last week I found another and grabbed it really quick. When I fired Cowboy Action rounds in it the gun was a dream. It didn't flop around and get hard to control. I carry it in a "Huckleberry rig" as a second CASS revolver and I intend to get a belt holster and carry it there in my "normal" life.
