Keeping your Gun Holstered!
Moisture is not your gun’s friend, which is why a moisture or vapor barrier on a gun holster is a crucial feature. A good holster is going to keep your gun clean, ready for use, and dry. Keeping the gun clean is relatively easy, since it’s tucked into a pouch. As long as you remember where you’re wearing the holster, it’s ready to use. Dryness is another story.
Even if you’re not standing in the middle of a downpour with your gun, humidity can work against you in a few ways. Moisture in the air can collect on your gun, which makes everything damp and creates a good environment for surface rust. It’s also worth noting that if it’s humid outside, you’re more likely to sweat. If you’re carrying your gun in a shoulder holster on a hot day, the vapor barrier nylon gun holsters will keep the gun dry, even if you’re not.
Think of it this way: you wouldn’t consider storing your gun in a damp locker outside, where it’s vulnerable to wetness or temperature and humidity fluctuations. A vapor barrier in your holster is like storing your gun after it’s oiled and cleaned, and throwing in a few silicone packets to absorb moisture in the air. It will protect your gun and keep the metal finish in good condition. USAHOLSTER.com also has a wide range of ammo accessories with vapor barrier protection as well.
