Beginner's Guide to Magazine Capacity Laws and Using Extensions Responsibly
Posted by on
Magazine capacity extensions, like the popular Ghost MOAB +6 extensions, are a fantastic way to increase the firepower of your firearm, whether for competition, home defense, or just a more convenient range session. However, for new gun owners, navigating the legal landscape surrounding magazine capacity can be confusing. Before you upgrade your magazines, it is absolutely essential to understand and comply with all federal, state, and local laws.
Understanding Magazine Capacity Laws
Unlike federal laws, which primarily regulate the transfer of firearms, magazine capacity limits are typically dictated at the state and sometimes the local level. These laws are not uniform and are constantly subject to change. What is legal in one state may result in a felony charge in a neighboring state.
State-Level Restrictions
A growing number of states have enacted laws that prohibit or restrict the sale, transfer, or possession of "high-capacity" magazines. While the term "high-capacity" is often a legal term of art, it usually refers to magazines capable of holding more than 10 or 15 rounds. For example:
- Some states limit all magazines to 10 rounds.
- Other states may have a higher limit, such as 15 rounds.
- There may be "grandfather clauses" allowing the possession of magazines acquired before a certain date, but this is state-specific.
It is your personal responsibility to research the specific laws of your state, and any state you plan to travel through or visit, before purchasing or installing a magazine extension.
Using Magazine Extensions Responsibly
Ghost Inc. products, including our reliable magazine extensions, are designed for maximum performance. Responsibility, however, is the user's domain. Here are a few tips for using extensions responsibly:
Know Your Capacity
When using an extension like the Ghost MOAB +6 on a standard 17-round Glock magazine, your total capacity increases significantly. Always know the resulting capacity of your modified magazine and ensure it is compliant with the laws in your current jurisdiction.
Practice Safe Storage and Transport
Even if an extended magazine is legal to possess, laws regarding storage and transport (especially when traveling across state lines) can be complex. Always transport firearms and magazines in accordance with local regulations and the Firearm Owners' Protection Act (FOPA) when applicable to interstate travel.
Prioritize Functionality
While extended magazines are great for capacity, always test them thoroughly at the range to ensure perfect feeding and function with your specific firearm and ammunition. Your life may depend on reliable performance.
Final Responsibility Check
The burden of compliance rests solely with the individual user. Ghost Inc. manufactures products for lawful use, but we cannot provide legal advice. If you have any doubt about the legality of a magazine capacity extension in your area, consult with a qualified attorney specializing in firearm law.
Stay informed, stay compliant, and train safely with your upgraded gear. You can find all of our magazine extensions and other high-performance parts on our Ghost Inc. homepage.
