The MTM Flip-Top Ammo Box for 40 S&W, 10mm Auto, and 45 ACP is a purpose-built storage and range companion for serious handgun shooters. Whether you're running a box of factory ammo through your carry gun, testing reloads, or stocking up for a long session downrange, this handgun ammo box holds 100 rounds and keeps everything organized and protected. MTM invented the flip-top handgun ammo box over 30 years ago, and this design remains a workhorse in range bags and reloading rooms across the country.
Built from durable plastic with a textured, scuff-resistant grip surface, the Case-Gard P-100 is designed to take the wear and tear of regular use. The Snap-Lok latch and full-length mechanical hinge are built to last—MTM backs them with a 25-year guarantee. Boxes are stackable, so you can consolidate your inventory without eating up shelf space. Each box is clearly labeled by caliber on the bottom, and a load label is included so you can track what you're storing and when you loaded it—especially handy if you're keeping multiple handgun calibers on hand.
Made in the USA at MTM's factory in Dayton, Ohio, this ammo box brings no-nonsense American manufacturing to a simple, essential job: keeping your rounds safe, sorted, and ready to go.
