I’m not speaking for clintbailey but I looked at his picture and it doesn't look like it’s a full length ejector rod housing.Do I understand correctly that the Bisley model ejector is full length? Kicks empty brass all the way clear out of the cylinder? I bought a NM SBH a few years ago and am a little dissatisfied with the short stroke ejector rod. 2/3 length ejection, maybe.
There are full length ERH’s but typically they are just standard length on Blackhawks, Super Blackhawks, etc.
I believe the only differences between the SBH’s and a Bisley model gun is on the bisley’s the grip frame, trigger, hammer and the scroll work on the cylinder is different.
