...a lot of subtlety in that pair. I'm not sure what a 'black powder chamfer" is or does, but that mild bevel on the cylinder adds some character and a softness to the look of the whole gun.
The grain you wanted to highlight is pretty clear through your photos. Funny, I always thought micarta was a smooth synthetic material of just one single uniform color until I got white micarta on my 83. They look a lot like the grain on your 7.5". Regardless, both are sharp.
If you haven't done so already, I think you should post these on the FA Eye Candy thread. Be a shame for these not to get more exposure. And after that you should put that camera down, load some ammo and get these shooters dirty!
