Nice rig!! It it a Bisley style grip frame? I looked at the same gun only in .454 Casull but opted for the Ruger Toklat, pretty much due to the fact it was already set up for a scope if I choose to ever use one. When looking at the BFR I did not remove the grips to see what the grip frame was but it did feel comfortable in my hand. I must say I AM NOT a fan of the Bisley grip in any way, shape or form.
