Nice! Can't complain about POI! All of my original and New Vaqueros needed 'adjustment' to shoot to POA.
BTW, where did you find the particular revolver? That is 'exactly' the style I've been looking for. Blued, 45 Colt, Birdshead Sheriff. I have a Sheriff .44Spec, but as you say the Birdshead looks like it would be a bit more comfortable to CC. My trail guns (5 1/2") normally aren't concealed so not a problem for carry.
