Featuring ramped front sight for a snag free draw; firing pin is mounted directly to the hammer; 6 shots of .357 Magnum on tap in its steel cylinder; full underlug barrel adds additional weight which helps manage magnum recoil, further aiding recoil control and benefiting concealment is the round butt grip frame.
