You must take precautions to protect your firearms from corrosion as the temperature drops. When moisture accumulates in the air, it can cause metal surfaces to rust. It can damage your handguns and make them unsafe to use. Like most gun enthusiasts, you probably take your firearms out for a spin at every chance. You enjoy getting out and using your guns at the shooting range or outdoors. But did you know that exposure to cold weather can cause corrosion? Eagle Arms will discuss ten tips to protect your firearms from corrosion during winter!

How Winter Conditions Affect Your Weapons

1. Corrosion

One of the main ways that winter conditions can affect your weapons is through corrosion. Corrosion is the process by which metal is slowly eaten away by oxygen, chemicals, or other substances. In the case of firearms, corrosion can be caused by exposure to salt water, sweat, blood, and other corrosive substances.

2. Moisture

Moisture is another factor that can affect your weapons in winter conditions. Moisture can cause rusting, corrosion, freezing, and ice build-up. Additionally, moisture can make it difficult for ammunition to ignite, rendering your weapon useless in combat.

3. Cold Weather Can Make Your Gunpowder Less Effective

Gunpowder is the primary propellant in most firearms and is notoriously finicky regarding temperature. The powder can become damp and clumpy in cold weather, reducing its muzzle velocity and accuracy. Additionally, the powder may not ignite properly in cold weather, which can cause misfires.

4. Cold Weather Can Make Your Metal Parts Brittle

When exposed to cold temperatures, metal parts can become brittle and break more easily. It is especially true for small parts like springs and firing pins. Additionally, extreme cold can cause metal parts’ corrosion, leading to jams and misfires.

5. Cold Weather Can Make Your Plastic Parts Brittle

Just like metal, plastic can become brittle in cold weather. It is especially true for small parts like grips and sights. Additionally, extreme cold can cause the plastic to become warped, affecting your accuracy.

6. Cold Weather Can Make Your Lubricants Less Effective

Lubricants are used to keep your gun’s moving parts moving smoothly. However, in cold weather, oils can thicken and harden, which can cause your gun to jam or misfire. The extreme cold can also cause the lubricant to freeze, damaging your gun’s moving parts.

10 Tips to Protect Your Firearms from Corrosion This Winter

1 . Store Your Firearms in a Cool, Dry Place

The best tip to protect your firearms from corrosion is to store them in a cool, dry place. Humidity can cause corrosion, so it’s essential to keep your guns in an environment that is not too humid. A gun safe is an excellent option for storing your firearms, as it will help to keep them protected from both humidity and theft.

2. Use a Gun Sock or Other Type of Protective Cover

Another way to protect your firearms from corrosion is using a gun sock or other protective cover. Gun socks are made from various materials, such as cloth or neoprene, and can help keep moisture away from your guns. You can also use Silica gel packets inside your gun safe to absorb any moisture that may be present.

3. Apply a Thin Coat of Oil to Your Guns

Applying a light coat of oil to your guns can also help to protect them from corrosion. The oil will create a barrier between the metal and the air, which will help to prevent moisture from rusting. It’s essential to use a light oil so it doesn’t attract dirt or dust, which could also lead to erosion.

4. Use Rust Preventive Products on Your Guns

Several rust-preventive products on the market can help to protect your firearms from corrosion. These products typically come in the form of aerosol sprays or wipes and can be applied directly to the metal surfaces of your guns. Rust preventive products usually contain a lubricant, which can help keep your weapons working smoothly.

5. Keep Your Guns Clean and Well-Maintained

Another practical tip to prevent corrosion is to keep your guns clean and well-maintained. Regular cleaning will remove any dirt or debris that could cause rusting and allow you to inspect your guns for any signs of wear or damage. Keeping your weapons properly lubricated will also help prevent corrosion, minimizing friction and wear on the metal surfaces.

6. Use a Desiccant

Another way to protect your firearms from corrosion is to use a desiccant, such as silica gel packets or desiccant beads. Desiccants help to absorb moisture from the air, which can prevent erosion. You can purchase desiccants online or at many hardware stores.

7. Store Your Ammunition Properly

Storing your ammunition correctly is another critical step in preventing corrosion. Ammunition should be kept in a cool, dry area and away from moisture and humidity. It’s also important to store different types of ammo separately, as some types are more corrosive than others.


8. Inspect Your Guns Regularly

Inspecting your guns regularly is also crucial for preventing corrosion. Be sure to check for any signs of rust or corrosion; if you see any, take steps to remove it immediately. Additionally, it’s essential to inspect your guns for any cracks or damage that could let the moisture get inside, leading to corrosion.

9. Use the Proper Cleaning Supplies

Using the proper cleaning supplies is essential for preventing corrosion. Be sure not to use harsh chemicals or abrasives when cleaning your firearm, as these can damage the finish and potentially lead to rusting. Instead, opt for mild soap, water, or a quality gun-cleaning solution.

10. Avoid Contact with Salt Water

Saltwater is one of the biggest enemies of firearms, as it can cause severe corrosion. If your gun is exposed to salt water, rinse it thoroughly with fresh water afterward. Additionally, avoid storing your firearm near salt water, as this can also lead to corrosion.
