No, I haven't actually. Most guys want the F/A because they are so strong, and finely made, and they are too. If you haven't ever fired one or owned one you are missing out on a fantastic gun. Even after LOTS of full power rounds, they are as tight as the day they left Freedom Wyoming, and they will stay that way. They are lco a bank vault.
I know Bowen does them, and he will only do them on the SRH because of recoil being so stout. I don't care for the SRH frame as far as looks go. I think a shortened X frame would be very cool. also, I would like to see them with one piece barrels like the older guns. I can't get excited about the way the two piece look either. I wouldn't want the muzzle brake/compensator. Just a 6" barrel and shorter frame/cylinder, and I would be a happy guy.
