I heard that it comes with a setscrew to keep the IL from engaging each time that it is fired, although it has not been confirmed that anyone actually cares - no one yet has desired to fire a second shot.
Yeah, I read that you can easily install an auto sear (or was it a bump grip?) so that when you whip that baby out you are ready for some serious action!
IIRC, S&W had a .357 J frame prototype in the 1960's. They never went beyond the proof of concept because they didn't think there was a market due to the recoil.
Had to due a double take on that one. Yes, I saw that it was posted yesterday. These days nothing would surprise me. Bond Arms makes a Derringer in 45-70 so a J-frame 500..............
