Preparing for the Project
The most critical element of any undertaking involving firearms is unwavering adherence to safety protocols. This section is absolutely paramount and must be taken with the utmost seriousness.
Firearm Safety Rules
Never forget the fundamental principles of firearm safety. Treat every firearm as if it is loaded. Never point a gun at anything you are not willing to destroy. Keep your finger off the trigger unless you’re ready to fire. Be certain of your target and what lies beyond. These safety protocols are not suggestions; they are non-negotiable.
Clearing the Magazine and Firearm
Prior to commencing any work on a magazine, it is essential to confirm that both the magazine and the firearm are completely unloaded. Remove the magazine from the firearm. Physically inspect the magazine to ensure it is empty. Open the action of the firearm and visually inspect the chamber to verify that no round is present. Operate the action to ensure that no rounds remain. Take further steps to be sure the firearm is unloaded. This is the first, and potentially most important, safety step.
Safe Work Environment
Establish a safe, well-lit, and organized workspace. The location should be free from distractions and well-ventilated. Ensure you have adequate lighting to see the details of the work, and keep tools and materials organized and readily accessible. Avoid working in an area where children or unauthorized individuals have access to firearms or related equipment.
Gathering the Necessary Tools and Materials
Assembling the right tools and materials is essential for a successful and safe magazine pinning project. The following list includes the necessary items:
Magazine(s) to be Pinned: These are the magazines that you intend to modify. Ensure the magazines are designed to be disassembled.
Pin: The most critical component. The pin can be a steel dowel or a similar durable material. The dimensions of the pin (diameter and length) are critical. Select a pin diameter which is correct and works well with the magazine. It must be long enough to restrict the follower’s movement and thus capacity.
Drill and Drill Bits: A hand drill or drill press is needed to make the hole for the pin. Choose drill bits that correspond to the pin’s diameter. Several drill bits might be needed, starting with a smaller size and gradually increasing the bit size to reach the final dimension.
Measuring Tools: Precision is paramount. A ruler, calipers, or other measuring tools are critical for precise measurements. Accuracy prevents overfilling or underfilling the magazine.
Vice: A vice is a recommended, but not always strictly necessary, tool. It securely holds the magazine, creating a stable platform while drilling. This helps prevent damage to the magazine.
Marker/Pen: A marker or pen is for marking the drilling location with precision. This needs to be a high contrast marker so you can see the spot.
Protective Eyewear and Gloves: Always wear protective eyewear to prevent injury from flying debris or metal shavings. Gloves provide better grip and also protect your hands from potential hazards during the modification process.
Optional: Epoxy or Other Permanent Bonding Agent: These are used to secure the pin more permanently, ensuring it does not move or dislodge during use.
Optional: Follower Stop: Some magazines might have a stop feature which is made to only allow the magazine to hold a set number of rounds. Check to see if your magazine can use a follower stop.
Step-by-Step Guide to Magazine Pinning
This section provides a detailed, step-by-step guide to the magazine pinning process.
Disassembly of the Magazine
Begin by disassembling the magazine. Each magazine design varies. Therefore, consult the manufacturer’s instructions or online resources if necessary. Generally, this process involves the following steps:
Baseplate Removal
Using a magazine tool or other appropriate device, carefully detach the baseplate from the magazine body. Be cautious, as the spring is under tension and could cause injury if released improperly. Many baseplates are removed by sliding the baseplate off the body or depressing a button.
Spring and Follower Removal
Once the baseplate is off, the spring and follower can be removed. Slowly ease the spring out, controlling its expansion. Be very careful here because this is often the step where the spring and follower can be damaged.
Determining the Pin Placement
Accurate pin placement is essential to restrict the magazine’s capacity to the desired number of rounds. Calculating the correct location demands careful measuring.
Magazine Follower Movement
The goal is to allow the follower to move up within the magazine only far enough to accept the legally allowed number of rounds. The pin will be placed to block the follower’s further upward movement.
Precise Measurement
Insert a dummy round into the magazine and measure how much space is left above the round inside the magazine body. Use a ruler or caliper to measure the total space. Then, calculate the total space for the number of rounds in question. Use the measurement to mark the location for the pin.
Checking with Dummy Rounds
Partially reassemble the magazine and use dummy rounds to ensure the follower stops at the correct point, preventing the magazine from holding more than the specified number of rounds.
Drilling the Hole
Once the pin location is determined, the drilling process begins. Precision and caution are key.
Marking the Spot
Clearly mark the exact location for the pin hole on the magazine body using a marker or pen. This mark is your target.
Drilling Procedure
Start Small: Begin with a smaller drill bit to create a pilot hole.
Gradual Increase: Slowly increase the drill bit size to match the diameter of the pin.
Slow and Steady: Drill slowly and carefully. This minimizes the chance of damaging the magazine body.
Avoid Burrs: After drilling, remove any burrs or rough edges that might hinder the magazine’s function.
Installing the Pin
The pin installation secures the modification.
Insertion
Insert the pin into the drilled hole. The pin must fit snugly.
Securing the Pin
If using epoxy, apply a small amount of epoxy around the pin and within the hole. Make sure it is set. Allow the epoxy to cure completely according to the manufacturer’s instructions.
Alternative Attachment
If using a press fit pin, ensure it is inserted firmly to prevent movement.
Reassembly and Testing
Following pin installation, the magazine must be reassembled and functionality tested.
Reassembly Steps
Reassemble the magazine by reversing the disassembly process. Ensure the spring is correctly seated and the follower moves smoothly.
Thorough Testing
Load Test: Load the magazine with the maximum legal capacity (in this case, ten rounds).
Additional Round Test: Attempt to load one additional round. The additional round should not enter the magazine.
Functionality Test: If safe and legal, test the modified magazine in the firearm to ensure it feeds properly. Check for jams or any other operational issues.
Alternative Pinning Methods
While this article focuses on the most common method, there are alternate ways to restrict the magazine’s capacity, though these are often less commonly used.
Using a Follower Stop
Some magazine designs incorporate a follower stop, a small component placed inside the magazine to physically limit the upward travel of the follower. This prevents the magazine from holding more than the specified number of rounds. The follower stop often is a specific part of the magazine.
Epoxy Placement
Epoxy can be applied inside the magazine to restrict capacity without requiring a pin. The epoxy fills space to restrict the follower travel. This method must be implemented with considerable precision to avoid damaging the magazine.
Troubleshooting
Even with meticulous effort, problems can occur. This section addresses common issues and their possible solutions.
Magazine Doesn’t Hold Exactly Ten Rounds
Recalibration: Recheck all measurements and make sure they are correct.
Pin Adjustment: Make minor adjustments to pin placement or drill a new hole if necessary.
Magazine Doesn’t Feed Properly
Obstruction Check: Carefully inspect the magazine for obstructions.
Spring and Follower Inspection: Ensure the spring is correctly seated and the follower is not damaged.
Pin Comes Loose
Epoxy Application: Remove and replace the pin, using a stronger adhesive, such as a high-quality epoxy.
