Compatibility with the 18.5 barrel security model

The Stevens 320 shotgun is available in a security model with an 18.5-inch barrel length. This firearm features a smooth, reliable pump action, a proven rotary bolt, and dual slide-bars. It has a bottom-loading tube magazine and a five-plus-one capacity.

Compatibility with the 18.5-inch barrel security model may vary depending on the specific extension being considered. For example, the Choate +1 extension is recommended for use with the 18.5-inch barrel length by a verified owner of the product. However, some users have reported issues with the threads on the Choate extensions not matching the threads on their Stevens 320 shotguns, even with the 18.5-inch barrel. In some cases, users have had to modify the extension or their firearm to achieve a proper fit.

It is recommended that all Savage parts be installed by a qualified and trained gunsmith. Before purchasing and installing a magazine extension, it is important to carefully research the compatibility of the extension with your specific firearm and to consult with a professional if you have any questions or concerns.

Installation process and issues

The installation process for adding a mag extension to a Stevens 320 shotgun involves several steps and considerations. Firstly, it is important to source a compatible mag extension, such as the Choate Tool Stevens 320 Magazine Extension, which offers a +1 or +2 round capacity increase. This particular extension has a matte finish and is designed for the 12-gauge variant of the Stevens 320.

During the installation, you will need to remove the existing magazine tube and replace it with the new extended tube. This typically involves unscrewing or unclamping the original tube and carefully screwing on the new one, ensuring that the threads match up correctly. It is important to note that some users have reported issues with the threads not aligning properly, so it may be necessary to contact the manufacturer for guidance if this issue arises.

Additionally, you may need to modify the spring and follower. This could involve cutting the spring to the appropriate length and potentially reusing the original follower, as some users have reported that the provided follower did not fit their shotgun. It is also worth noting that the mag extension comes with a clamp, which will need to be correctly positioned and secured.

Finally, it is important to check the operation of the shotgun after the installation to ensure that the mag extension is functioning as intended and that the shotgun cycles and feeds rounds reliably. This may involve test-firing the shotgun at a safe location, such as a shooting range, to ensure that the modifications have not affected the performance of the weapon.

While the process may seem straightforward, it is important to approach the installation with caution and to seek expert advice if you are unsure about any steps. It is also worth noting that modifying your firearm may have legal implications, so it is crucial to consult relevant laws and regulations before proceeding with any alterations.

Legality of the extension

The legality of adding a magazine extension to a Stevens 320 shotgun depends on the specific jurisdiction and the relevant firearms laws and regulations in that area. In the United States, for example, the federal government has placed restrictions on the capacity of certain firearm magazines, with some states also having their own laws regarding magazine capacity.

The Stevens 320 shotgun is a popular choice for home defence and tactical applications, and owners of this firearm may seek to increase its ammunition capacity by adding a magazine extension. Magazine extensions for the Stevens 320 are commercially available, offering an increase of one or two rounds to the original capacity.

When considering the legality of adding a magazine extension to a Stevens 320, it is important to consult the relevant firearms laws and regulations in your jurisdiction. In some places, there may be restrictions on the maximum capacity of firearm magazines, which could make the use of a magazine extension illegal. It is also important to note that firearms laws can vary significantly between jurisdictions, and what may be legal in one area may not be legal in another.

As an example, in the United States, the federal government has placed restrictions on the sale and possession of certain high-capacity magazines. These restrictions, which are outlined in the Unlawful Firearms Commerce Control Act, generally prohibit the sale or transfer of magazines with a capacity of more than 10 rounds for rifles and more than 15 rounds for shotguns. However, it is worth noting that these restrictions do not apply to magazines that were manufactured before the enactment of the law, which was on September 13, 1994. Additionally, some states within the US have their own laws and regulations regarding magazine capacity, which may be more restrictive than federal law.

Therefore, when considering the legality of adding a magazine extension to a Stevens 320, it is crucial to consult the specific laws and regulations in your jurisdiction. This may involve researching federal, state, and local firearms laws, as well as seeking guidance from legal experts or law enforcement agencies. It is also important to keep in mind that firearms laws can change over time, so it is essential to stay informed about any updates or amendments that may impact the legality of your firearm modifications.
