25 AUTO Ammo

John Browning designed 25 ACP ammo, or 25 automatic colt pistol, to work with his Fabrique Nationale 1906 pistol. This small, but well made pistol was designed to maximize the concealment potential of a pistol.

25 Auto is a 6.35x16mm round designed to be used in early blowback pistols lacking a breech locking mechanism. The 25 ACP cartridge is small, and generally lightly loaded. It’s size makes the caliber fairly easy to control but it is still powerful enough to penetrate the required 12 inches of ballistic gel test the FBI utilizes to determine the lethality of a round.

25 ACP is one of the smallest centerfire calibers there is, and for quite some time was the smallest center fire round available. A centerfire cartridge, look for 25 ACP ammo for sale here from well-known manufacturers located all over the planet. When possible, we work to keep a steady supply of full metal jacket (FMJ) and hollow point ammo in-stock so you’re covered whether you need training ammo or self-defense rounds to defend yourself, your family and your home.

    I've been using Magsafe in .25 auto for years and it's the BEST AMMO there is! I can hit my target with much more smaller groups. You would think that the faster load would be harder on your hands with the Berrata 950, but it's not. It's the BEST AMMO Period. BUY THEM !!!
