  1. Rossi RP63, 357 Magnum, Notes, Thoughts, Basic Tuning and Grip Options

    .011" was removed from the foot of the 720 hammer bringing it's total height to match the .050 foot of the factory RP63 hammer foot. The tip of the 720 firing pin was moved to the same resting position as the factory RP63 pin. A full .050" forward movement. Pin is enclosed, sufficient space is...
  2. Rossi RP63, 357 Magnum, Notes, Thoughts, Basic Tuning and Grip Options

    The foot of the 720 hammer is a bit longer than the factory RP63 hammer and holds the hammer nose farther out when the rebound slide pushes the firing pin clear of the primer at trigger reset. The combined height of the tenons on the hammer and rebound slide determine both resting position and...
  3. Rossi RP63, 357 Magnum, Notes, Thoughts, Basic Tuning and Grip Options

    6 rounds at 10 yards.....looks like we're ready to go Bear Hunting.
  4. Rossi RP63, 357 Magnum, Notes, Thoughts, Basic Tuning and Grip Options

    The new look......Rossi should offer this....its touted as a concealment revolver, spur less makes sense.
  5. Rossi RP63, 357 Magnum, Notes, Thoughts, Basic Tuning and Grip Options

    The RP63 Mainspring strut and spring clip were removed. Installed are the 720 mainspring strut and spring ball. I used the RP63 mainspring since it is newer and a lower spring rate than the old and higher rate 720 spring. Nope, the spring ball doesn't slip thru nor move around, it works fine to...
  6. Rossi RP63, 357 Magnum, Notes, Thoughts, Basic Tuning and Grip Options

    Model 720 SS Spur-less Hammer (Not MIM) is not a direct fit. RP63 MIM hammer shown left. The 720 hammer needs the axle hole drilled and reamed to .140 inch. Easily done on a drill press and this steel drills a darn site easier than MIM. The hole was then deburred. The left side of the hammer...
  7. Rossi RP63, 357 Magnum, Notes, Thoughts, Basic Tuning and Grip Options

    Model 720 SS (not MIM) trigger is a direct fit. (RP63 MIM Trigger below). Simply cleaned it, polished and installed using the RP63 Cylinder Hand (as its already fitted to the cylinder) and used the RP63 MIM Cylinder Bolt (As its already fitted to the cylinder. RP63 Rebound slide works fine...
  8. Rossi RP63, 357 Magnum, Notes, Thoughts, Basic Tuning and Grip Options

    So, continuing to experiment on this handgun. Previously, converted to Taurus 856 Boot Grip and screw retention vice pin for the grip. Also, barrel shortened to 2 7/16 inches with Taurus 856/Ameriglo Orange/Tritum front sight, changed rebound spring. Since there are no bobbed hammer/spur less...
  9. Taurus 856, 38 Special, Notes, Thoughts and Basic Tuning

    All done but removal of the hammer blocking screw, and for that, I'll have to round up a Taurus Key, just don't want to pay $15 shipped to get one..... (The spur-less hammer is 37 grains lighter, as shown here, than the original spurred hammer.) Had it out to the backyard range and function is...
  10. Taurus 856, 38 Special, Notes, Thoughts and Basic Tuning

    Test fitting the new spur-less hammer in the action. Function is just fine. Out for a final polish, cleaning and lubrication of all the points of contact.
  11. Taurus 856, 38 Special, Notes, Thoughts and Basic Tuning

    Hammer axle in the frame is .140" dia. Hole in the spur-less hammer is .120". Shown here with the hole reamed and polished to a free running fit on the axle, edges of the new axle hole chamfered, bluing buffed off and the arc at the top of the hammer stoned a few thousands to eliminate one spot...
  12. Taurus 856, 38 Special, Notes, Thoughts and Basic Tuning

    Back in the 90s Taurus made a snub nose, spur-less hammer, small frame revolver for concealed carry in caliber 17 HMR. Not the Tracker, which is a medium frame but on the small frame. I believe the model is long defunct but I located a like new spur-less hammer from one for $12. So, time for a...
  13. Rossi 62.4

    Before and after...
  14. Rossi 62.4

    So....shortened and profiled the barrel to 2 7/16 inches, saving all the markings. Reprofiled the Ameriglo orange/tritium to face up a bit and catch the light better. Made room in the bottom of the original sight slot for the now smaller foot of the Ameriglo. Gave the muzzle a recessed 11...
