Ruger GP100Model: Ruger GP-100
The Ruger GP-100 is one of the most popular families of modern American revolvers. All GP-100 revolvers are made entirely of steel, either stainless or blued. They can purchased with fixed or fully adjustable sights, several barrel lengths, and several different calibers. In other words, there's a GP-100 for almost any use.

All revolvers can be fired in double or single-action and include a triple cylinder lock, with the cylinder locking into the frame at the front and rear of the crane and on the cylinder lock itself.

Complexity

The GP-100 can be disassembled with limited usage of tools, though still more than would be needed for a semi-automatic being field stripped. However, the triple cylinder lock and lack of need for a frame sideplate gives the gun a reputation for strength and durability, as well as all the other advantages to a revolver in reliability.

    Loading

    Condition One, or "Locked and Cocked." Chamber loaded, magazine full, hammer cocked and safety applied.

      Cannot be done.
    Condition Two. Chamber loaded, magazine full, hammer down, safety off.

    1. Point the weapon in a safe direction. Critical step in case it accidentally discharges!
    2. Push the cylinder catch and push the cylinder to the left with your fingers from the right side.
    3. Take the appropriate number of cartridges and push them all the way into the chambers in the cylinder.
    4. Push the cylinder shut.

    Condition Three. Chamber empty, magazine full, hammer down, safety off.
      This is not a "true" Condition Three, but works essentially the same.
      1. Point the weapon in a safe direction. Critical step in case it accidentally discharges!
      2. Push the cylinder catch and push the cylinder to the left with your fingers from the right side.
      3. Take the appropriate number of cartridges and push them all the way into the chambers in the cylinder, leaving one chamber empty.
      4. Rotate the cylinder so that the empty chamber is at the top and push it closed, leaving the hammer resting on an empty chamber.

      Field Stripping

      How to disassemble the firearm for cleaning. Presented in a numbered list.

      1. Point the weapon in a safe direction. Critical step in case it accidentally discharges!
      2. Unload the weapon as described above.
      3. Remove the grip screw and remove the pistol grip inserts.
      4. Remove the grip panel locater and pull the grip downward off the frame.
      5. **** the hammer and insert the disassembly pin about halfway into the hole at the rear of the mainspring strut. Without the disassembly pin, any similarly-sized object will work.
      6. With your thumb on the hammer, squeeze the trigger and gently lower the hammer forward. While keeping the disassembly pin in place, remove the mainspring assembly. Do NOT remove the pin until the assembly is back in the revolver, or the mainspring will shoot out.
      7. Hold the trigger back and remove the hammer pivot. Lift the hammer out of the frame.
      8. Use the mainspring assembly to push the trigger guard lock plunger in the frame at the rear of the trigger guard. While holding it down, pull down and remove the trigger guard assembly. If you cannot apply sufficient force with the mainspring assembly, use a screwdriver.
      9. Swing out the cylinder assembly and pull it forward off the frame.
      Reverse to reassemble.

      A fine pistol. If you need a workhorse .357 that will last years, the Ruger is nothing short of a soild investment, that with proper care, should show a good return on your money, should you ever need to sell it. You can bet your life on in the meantime.
