Step 1: Ensure the Firearm is Safe

Before handling any firearm, always ensure it is unloaded and safe. Remove the magazine and visually inspect the chamber to confirm it is empty. Point the firearm in a safe direction throughout the entire process.

Step 2: Remove the Bolt from the Pistol

Follow the instructions in your owner’s manual to remove the bolt from the Ruger MK IV pistol. This typically involves field stripping the pistol and then sliding the bolt out of the receiver.

Step 3: Identify the Components

Familiarize yourself with the components of the bolt. You’ll typically find the firing pin, firing pin spring, firing pin retaining pin, extractor, and extractor spring.

Step 4: Depress the Firing Pin Retaining Pin

This is the crucial step in learning how to strip a Ruger MK IV bolt. Using your small punch or tool, carefully depress the firing pin retaining pin. This pin holds the firing pin in place.

Step 5: Remove the Firing Pin

With the retaining pin depressed, gently push the firing pin forward and out of the bolt. Be careful not to lose the firing pin spring.

Step 6: Remove the Firing Pin Spring

Carefully remove the firing pin spring from the bolt.

Step 7: Remove the Extractor

The extractor is usually held in place by a small pin or detent. Use your small punch or tool to carefully push out the extractor pin (if present) and remove the extractor and extractor spring. Some extractors may simply be pried out carefully.

Step 8: Clean All Components

Now that you have disassembled the bolt, thoroughly clean all the components. Use your cleaning solvent, patches, and bore brush to remove any carbon buildup, lead deposits, or other debris. Pay particular attention to the firing pin channel and the extractor claw.

Reinstall the extractor and extractor spring. If there is an extractor pin, make sure it is properly seated.

Step 3: Reinstall the Firing Pin Spring

Place the firing pin spring back into its recess in the bolt.

Step 4: Reinstall the Firing Pin

Insert the firing pin into the bolt, making sure it is properly aligned.

Step 5: Depress the Firing Pin Retaining Pin and Secure the Firing Pin

Depress the firing pin retaining pin again and push the firing pin fully into place. Release the retaining pin, ensuring it securely locks the firing pin in position.

Step 6: Test the Firing Pin

After reassembling the bolt, test the firing pin to ensure it moves freely and strikes the firing pin stop appropriately. You should feel a distinct click when the firing pin is released.
