Brief history of the Ruger GP100
The Ruger GP100 was introduced by Sturm, Ruger & Co., Inc. in 1985. It was designed as a replacement for the Ruger Security Six revolver, which was discontinued in 1988. The GP100 was initially offered in a stainless steel finish, with a fixed rear sight and a ramp front sight. Over the years, Ruger introduced various enhancements and models of the GP100, including different barrel lengths, grip options, and special editions.
Understanding the Parts of the Ruger GP100
To effectively clean and disassemble the Ruger GP100, it is important to familiarize yourself with its different parts:
The barrel of the Ruger GP100 is where the bullet travels through after being fired. It is an essential part of the revolver and must be cleaned regularly to maintain accuracy and prevent corrosion.
The frame of the GP100 holds all the internal components in place and provides structural support to the revolver. It is made of stainless steel, providing durability and resistance to wear and tear.
The cylinder is the rotating part of the GP100 that holds the ammunition. It contains chambers where the cartridges are loaded and fired. The cylinder must be cleaned and lubricated to ensure smooth rotation and reliable function.
The grips of the Ruger GP100 are the handles that allow the shooter to hold and control the revolver. They are available in various materials and styles, providing comfort and customization options.

Preparing for Disassembly
Before starting the process of disassembling the Ruger GP100, proper preparation is crucial to ensure safety and organization. Follow these steps to get ready:
Gathering necessary tools
To disassemble the GP100, you will need a few basic tools, including a flathead screwdriver, a clean cloth or patches, a cleaning rod, cleaning solvents, lubricants, and a gun cleaning kit. Make sure all the tools are clean and in good condition.
Ensuring firearm safety
Safety should always be a top priority when handling firearms. Before disassembling the GP100, ensure it is unloaded by confirming that there are no cartridges in the cylinder and no ammunition in the vicinity. Remove the grips for better access to the internal components.
Clearing all ammunition
It is essential to remove all ammunition from the area where you will be working on the GP100. Keep the ammunition stored in a separate location to prevent accidental loading and discharge during the disassembly process.
Step-by-Step Guide to Disassembling the Ruger GP100
Follow these step-by-step instructions to disassemble the Ruger GP100 properly:
Removing the cylinder
To remove the cylinder, make sure the revolver is unloaded and the hammer is in the half-cocked position. Hold the revolver with one hand and push the cylinder release, located on the left side of the frame, forward. This will allow the cylinder to swing out. With the other hand, gently pull the cylinder to remove it from the frame.
Taking off the grips
Removing the grips will provide better access to the internal parts of the GP100. Using a flathead screwdriver, carefully unscrew the grip screw located at the base of the grip on both sides of the revolver. Once the screws are removed, gently lift and slide off the grips.
Disassembling the frame
With the cylinder and grips removed, you can now proceed to disassemble the frame. Start by locating the mainspring assembly, which is located on the backstrap of the frame. Use the flathead screwdriver to push the mainspring assembly forward, releasing it from its position. Carefully remove the mainspring assembly from the frame.
Detaching the barrel
To detach the barrel from the frame, locate the barrel mounting screw located on the underside of the frame, just in front of the cylinder. Use the flathead screwdriver to carefully unscrew the barrel mounting screw, ensuring not to damage the threads. Once the screw is removed, gently lift and slide the barrel forward to detach it from the frame.
Removing the sights
The sights of the GP100 can be removed for thorough cleaning or replacement. To remove the rear sight, locate the set screw on top of the frame, just in front of the rear sight. Use the appropriate tool to loosen and remove the set screw. Once the set screw is removed, gently lift and slide the rear sight forward to detach it from the frame. To remove the front sight, use a screwdriver or a sight tool to unscrew and remove it from the barrel.
Dismantling the trigger assembly
To dismantle the trigger assembly, locate the trigger spring located on the underside of the frame, just behind the trigger. Use a flathead screwdriver to carefully push the trigger spring forward, allowing it to disengage from its position. Once the spring is released, gently lift and remove the trigger assembly from the frame.
Removing the hammer
To remove the hammer, locate the hammer strut pin near the bottom of the frame, just above the grip area. Use a punch or a small screwdriver to carefully push out the hammer strut pin. Once the pin is removed, gently lift and slide the hammer forward to detach it from the frame.

Cleaning the Ruger GP100
Cleaning the Ruger GP100 is an important step to maintain its performance and longevity. Follow these steps to clean each part of the revolver:
Choosing the right cleaning solvents
Selecting the appropriate cleaning solvents is crucial to effectively remove fouling and residues from the revolver. Ensure you have a gun-specific solvent, a bore cleaner for the barrel, and a degreaser for removing built-up lubricants.
Cleaning the barrel
Start by attaching a bore brush to the cleaning rod and applying a small amount of bore cleaner to the brush. Insert the cleaning rod with the brush into the barrel and push it back and forth, ensuring the entire length of the barrel is covered. Repeat the process with clean patches until they come out clean. Finally, apply a light coat of gun lubricant to a clean patch and run it through the barrel for protection.
Cleaning the frame
Using a clean cloth or a cleaning brush, remove any dirt, debris, or fouling from the frame. Pay attention to hard-to-reach areas and crevices. Apply a small amount of gun-specific solvent to the cloth or brush for stubborn residues. Wipe down the frame thoroughly and ensure it is clean and dry.
Cleaning the cylinder
To clean the cylinder, use a cleaning brush or a cloth soaked in a gun-specific solvent. Scrub the chambers and the front face of the cylinder to remove fouling and residues. Make sure to clean the extractor and the star ejector as well. Once the cylinder is clean, dry it thoroughly and apply a light coat of gun lubricant to ensure smooth rotation.
Cleaning the small parts
Clean the small parts, such as the sights, trigger assembly, and the hammer, using a cleaning brush and the appropriate solvent. Ensure all surfaces are thoroughly cleaned and free of dirt, grime, and residue. Dry the small parts and apply a light coat of gun lubricant for smooth operation.
Lubricating the firearm
After cleaning all the components, apply a small amount of gun lubricant to the moving parts of the GP100, such as the hammer, trigger, and cylinder. Use a clean cloth or your fingers to spread the lubricant evenly. Avoid applying excessive lubrication, as it can attract dirt and debris.
Reassembling the Ruger GP100
Follow these steps to properly reassemble the Ruger GP100:
Putting the hammer back
To reassemble the hammer, align it with the frame and carefully slide it back into its original position. Make sure the hammer strut aligns with the hole in the frame. Insert the hammer strut pin through the frame and the hammer to secure it in place.
Assembling the trigger assembly
Slide the trigger assembly back into the frame, ensuring it aligns correctly with the corresponding slots. Push the trigger assembly forward until it locks into place. Make sure the trigger spring is properly engaged and seated.
Attaching the sights
If you have removed the sights for cleaning or replacement, follow the manufacturer’s instructions to attach them securely. Ensure they are aligned properly and tightened according to the specified torque.
Reassembling the frame
Align the barrel with the frame and slide it back into its original position. Insert the barrel mounting screw into the underside of the frame and tighten it securely, ensuring it is not over-tightened. This will hold the barrel in place.
Installing the grips
Slide the grips back onto the frame, aligning them with the screw holes. Insert the grip screws and tighten them securely, ensuring they are evenly tightened to avoid any imbalance.
Reinserting the cylinder
Hold the GP100 with one hand and align the cylinder with the frame. Insert the cylinder pivot pin through the frame and the cylinder, ensuring it is secure and in place. Close the cylinder by pushing it back into the frame until it locks into position.
