    Q. Are your safes manufactured in the USA?

    Q. What is the maximum number of long guns that your Monster safes can accommodate?

    •  They can secure up to 100 long guns, depending on the configuration. Please note that scopes and accessories will require additional space. If your collection includes oversized long guns, we can customize the interior of your safe for optimal fit and accessibility.

    Q. Are you able to create gun safes in custom sizes and configurations? 

    • Definitely. We specialize in tailored safes and can manufacture them to nearly any dimension and design. Our capabilities include comprehensive custom CAD services. If you're in search of a personalized solution, please reach out for more details and a complimentary quote.

Reasons to Invest in a Large Gun Safe.


Many hunters and firearm enthusiasts tend to misjudge the level of secure storage required for their possessions. A gun safe serves more than just a purpose of securing firearms; it also accommodates ammunition, electronics, important documents, jewelry, and much more. It's advisable to invest in a spacious gun safe that is at least 30% larger than your current needs.


A large gun safe is designed to hold 40 or more long guns. All of our gun safes indicate their capacity for long guns. However, let’s be honest. When storing standard long guns without scopes or additional accessories, the stated capacities are accurate. Many collectors, however, own larger guns equipped with scopes and other gear, which must be considered when choosing a new safe. Our 750 model safes can hold up to 45 long guns, while our 760 series can accommodate as many as 60, and our Monster safes can hold up to 100 long guns. As the manufacturer, we also specialize in custom-sized safes and walk-in vaults tailored to accommodate extensive gun collections.


Vault Pro USA is a leader in American manufactured large gun safes for several reasons: quality, price and lifetime guarantee. Most competitors sell large gun safes made in foreign countries. We build all our safes at our facility here in the USA and ship factory direct.
