40 S&W Ammo Storage Box

.40 S&W Ammo Box – Built with the BoxLoc System

Designed specifically for .40 S&W ammunition, the BoxLoc .40 S&W Ammo Box provides a clean, durable, and modular way to organize your ammunition. Configured with the included insert, it securely stores 100+ rounds of .40 S&W while remaining fully compatible with the complete family of BoxLoc interchangeable inserts.

Built on the modular BoxLoc system, this design features smooth, rounded edges for comfortable handling, a durable integrated sliding hinge, and secure dual latches with oversized finger tabs for quick and reliable access.

Unlike traditional ammo boxes, the BoxLoc system is designed for flexibility. Removable inserts fit securely inside the box during transport but can be easily lifted out for loading, cleaning, storage, or transport. Because every insert shares the same modular platform, you can mix and match insert configurations within the same box to fit your needs.

This double-size BoxLoc Ammo Box is compatible with inserts for 9mm, 10mm, .22 LR, .380 ACP, .40 S&W, and .45 ACP. For example, you can combine a 50-round 9mm insert with a 120-round .22 LR insert, or pair 9mm and .45 ACP inserts inside the same box, allowing you to build the exact storage solution you want.

Lids and latches are also fully interchangeable across compatible BoxLoc products, making it easy to customize or update your box over time.

Every BoxLoc ammo box is precision 3D printed to order using high-quality materials and is carefully inspected before shipment. The rugged construction and stackable design make it ideal for range days, competition shooting, long-term storage, or keeping your ammunition organized in your gun safe.
