G_one, thanks for the kind words.
The birdshead feels a little different to hold, I will admit to not having had a chance to shoot it yet. It spent the first two months that I owned it back in Fredericksburg being fixed (have the dealers at gun shows cut those zip ties so's you can check the action, kids). Then the wife and I bought a house and moved to a new town. With all the goings on, I haven't shot anything in a while. Maybe this week.
More on point to your question, I don't see it being a big deal. I'm accustomed to different types of grips (I own a Glock AND a 1911!
), so I don't really give it much thought.
It's not a standard birdshead grip, it is the brainchild of the President of Cimarron, mating a regular 'ol 1873 upper frame to a Colt's 1877 double action style grip frame. The marketing was along the lines of "The gun Colt never made, but should have." There is a bit of a horizontal "shelf" at the top of the backstrap behind the hammer. Once it swoops down on the vertical, the curvature pretty well mimics the standard "plow handle" single action grip. Until it curves under near the bottom. Think round butt vs. square butt on a S&W.
I must admit I mainly like the way it looks. Dig the short barrel too.
Wow. That is a whole lot of rambling to not have a definitive answer. Hope it was of some help.
