The Ultimate Buying Guide for Your Benelli M2 Magazine Extension
If you own a Benelli M2 shotgun, you know it’s a fantastic firearm. Wanting more shots without reloading often is a smart move. A magazine extension lets you do just that! This guide helps you pick the best one for your needs.
Key Features to Look For
When shopping, check these things first. They make a big difference in how well the extension works.
Capacity Increase
- How many extra rounds? Extensions usually add 2, 3, or 4 shells. Decide how much extra firepower you need. More capacity means longer shooting sessions.
- Total Length: Longer extensions are great for capacity but might make the gun harder to carry or use in tight spaces.
Reliability and Feeding
- Spring Quality: The spring pushes the shells up. A strong, high-quality spring ensures every shot feeds smoothly. Weak springs cause jams.
- Follower Design: The follower guides the shells. Look for designs that prevent tilting or catching inside the tube.
Durability and Finish
- Secure Attachment: The extension must lock onto the barrel tube tightly. It should never wobble or unscrew itself during heavy recoil.
- Finish Quality: A good finish (like anodizing or tough coating) resists scratches and rust. Your shotgun lives in tough environments.
Important Materials Matter
The material determines how long the extension lasts and how much it weighs.
Aluminum Alloys
- Pros: Most popular choice. Aluminum is lightweight and strong enough for competition use. Good quality aluminum resists corrosion well.
- Cons: Cheaper aluminum can sometimes dent if hit hard.
Steel
- Pros: Very tough and durable. Steel extensions handle extreme abuse.
- Cons: Steel adds noticeable weight to the front end of your shotgun. It also needs good coating to prevent rust.
Plastics (Advanced Composites)
- Use Case: Less common for the main tube, but sometimes used for followers or end caps. They save weight.
Factors That Improve or Reduce Quality
Not all extensions are created equal. Good design boosts performance. Poor design causes headaches.
Quality Boosters
- Precision Machining: When parts fit perfectly, they don’t rattle or bind. High-quality extensions are machined with tight tolerances.
- Easy Installation: Extensions that use simple, strong clamps or threads are easier to install correctly.
- Lifetime Warranty: Manufacturers who back their products with good warranties usually build them better.
Quality Reducers (Watch Outs)
- Thin Walls: If the aluminum walls are too thin, they can deform under pressure or impact.
- Poor Threads: Rough or misaligned threads make installation difficult and can damage the original magazine tube threads.
- Light Springs: If the included spring is weak, you will experience feeding failures, especially when the tube is fully loaded.
User Experience and Use Cases
Think about why you shoot your Benelli M2. Your use case changes what extension you should buy.
3-Gun Competition Shooting
- Competitors need maximum capacity (often +4 or +5) and very fast loading. Extensions must be rugged enough for fast handling and prone shooting positions.
Home Defense
- For home defense, capacity is important, but reliability is everything. Many owners choose a +2 or +3 extension. This keeps the overall length manageable inside hallways while providing extra insurance rounds.
Hunting/Sport Shooting
- Hunters often prefer lighter setups. A +2 extension might be perfect. It offers a little extra capacity without making the shotgun front-heavy for long walks in the field.
10 Frequently Asked Questions (FAQ) About Benelli M2 Magazine Extensions
Q: Will installing an extension void my shotgun’s warranty?
A: Generally, adding a quality, non-permanent accessory like a magazine extension does not void the entire shotgun warranty. However, if the extension itself breaks the original magazine tube threads due to poor installation, Benelli might not cover that specific damage.
Q: Is it hard to install a magazine extension on the M2?
A: For most quality extensions, the process is straightforward. You usually remove the factory cap, thread on the new extension, and secure it with a locking nut or clamp. Basic tools are often required.
Q: Can I use the same extension on a Benelli M4?
A: No. The Benelli M2 and M4 use different magazine tube designs and thread patterns. You must buy an extension specifically made for the M2.
Q: Do I need a longer magazine spring when I add an extension?
A: Yes. When you increase capacity, you need a longer, stronger spring to reliably push all those extra shells up to the lifter. Most quality kits include the correct spring.
Q: How do I know if the extension is feeding reliably?
A: The best test is function testing. Load the magazine to its maximum capacity and fire several rounds slowly, then fire several rounds quickly. If you experience any failure to feed (a jam), the spring or follower needs adjustment or replacement.
Q: Will an extension make my shotgun too heavy?
A: A +3 extension adds weight, but it is usually manageable. If you add +5 or more, you will definitely notice the added bulk, especially during long shooting days. Weight depends heavily on whether the extension is aluminum or steel.
Q: Do I need a special tool to remove the factory magazine cap?
A: Often, yes. The factory cap is usually tightened very securely. You might need a specialized wrench or strap wrench to avoid scratching the cap when removing it for the first time.
Q: Are extended tubes legal everywhere?
A: In many states, shotguns are limited to a maximum capacity (often 5 rounds) for hunting. Competition or home defense use usually has fewer restrictions, but you must always check your local and state laws regarding magazine capacity.
Q: Should I use blue Loctite on the threads?
A: Some manufacturers recommend a small amount of thread locker (like blue Loctite) to prevent the extension from vibrating loose. Check the instructions provided with your specific extension kit.
Q: What is the follower, and why is it important?
A: The follower is the plastic or metal piece that sits on top of the spring. Its job is to push the shells upward. A well-designed follower slides smoothly and prevents the nose of the top shell from tilting down, which is a common cause of jams.
