Step-by-Step Disassembly Guide

Initial Preparation

As mentioned before, ensure the pistol is unloaded. Remove the magazine by pressing the magazine release button. Pull the bolt back and visually inspect the chamber to verify it’s empty. Point the pistol in a safe direction during this process.

Removing the Mainspring Housing Latch

The mainspring housing latch is located at the rear of the grip. Pull down on the latch and rotate it to the side. This will release the mainspring housing.

Removing the Mainspring Housing

With the latch rotated, the mainspring housing should slide down and out of the frame. You may need to gently wiggle it. Be careful, as the mainspring is under tension.

Removing the Bolt Stop Pin

Using a punch and soft-faced hammer, gently tap out the bolt stop pin. This pin holds the bolt stop in place.

Removing the Bolt Stop

Once the pin is removed, the bolt stop can be removed from the frame. Be mindful of the orientation, as it needs to be reinstalled correctly.

Removing the Bolt

Pull the bolt back slightly and lift it out of the frame. It might require a little maneuvering.

Removing the Firing Pin

The firing pin is located inside the bolt. To remove it, you’ll need to depress the firing pin retaining pin and slide the firing pin out. Be cautious, as the firing pin spring is also under tension.

Disassembling the Bolt (Optional)

Further disassembly of the bolt is usually not necessary for routine cleaning. However, if you need to replace parts, you can remove the extractor and ejector by drifting out their respective pins. Note the orientation of all parts before removal.

Removing the Trigger Assembly (Advanced)

Removing the trigger assembly is more complex and generally not required for basic maintenance. If you choose to do so, proceed with caution and consult a detailed guide or video. This involves removing several pins and springs, and it’s easy to lose or damage parts. [See also: Ruger Mark II Trigger Upgrade Guide]

Cleaning and Inspection

Now that you know how to disassemble the Ruger Mark II pistol, it’s time for cleaning and inspection. Use a high-quality gun cleaning solvent and brushes to remove any carbon fouling or debris from all parts. Pay particular attention to the barrel, bolt face, and firing pin channel. Inspect all parts for wear or damage. Replace any worn or damaged components.

Reassembly: Putting it All Back Together

Reassembly is essentially the reverse of disassembly. Follow these steps carefully:

Reassembling the Bolt

If you disassembled the bolt, reassemble the extractor and ejector, ensuring they are oriented correctly. Reinstall the firing pin and firing pin spring, securing them with the retaining pin.

Reinstalling the Bolt

Slide the bolt back into the frame, ensuring it is properly aligned.

Reinstalling the Bolt Stop

Insert the bolt stop into its slot in the frame. Reinstall the bolt stop pin, tapping it gently with a soft-faced hammer.

Reinstalling the Mainspring Housing

Slide the mainspring housing up into the frame, ensuring it is properly seated. Rotate the mainspring housing latch to secure it in place.

Function Check

After reassembly, perform a function check to ensure everything is working correctly. Cycle the bolt, pull the trigger, and verify that the hammer falls. Ensure the safety is functioning properly. If anything feels wrong, disassemble the pistol again and check for any errors in the reassembly process.

Troubleshooting Common Issues

Sometimes, you might encounter issues during disassembly or reassembly. Here are a few common problems and their solutions:

Difficulty Removing the Mainspring Housing: Ensure the mainspring housing latch is fully rotated. Apply gentle pressure while wiggling the housing.
Difficulty Removing the Bolt Stop Pin: Use a properly sized punch and apply firm, even pressure.
Difficulty Reinstalling the Bolt: Ensure the bolt is properly aligned with the frame. Check for any obstructions.
Failure to Extract: Clean the extractor and ejector thoroughly. Check for wear or damage.
Failure to Fire: Clean the firing pin channel. Check the firing pin for damage.

Clean After Each Use: Remove carbon fouling and debris after each shooting session.
Lubricate Regularly: Apply a light coat of gun oil to all moving parts.
Inspect Regularly: Check for wear or damage on all components.
