One of the features I really like about the BFR is the use of a screw through the cylinder pin to retain it. I have several Ruger revolvers that have the spring loaded pin that snaps into the detent on the cylinder pin. On a few of them with heavy recoiling loads, I've had the pin pop out of the detent and move forward, tying up the gun. That cannot happen with the BFR. Another thing I like is the use of Stainless steel socket head cap screws to secure the frame, and the way the cylinder free wheels in either direction when you open the loading gate. They used their heads when they built that gun. Bill T.
