About .25 Auto Ammunition

The .25 Automatic Colt Pistol, or .25 ACP, cartridge is the brainchild of John Moses Browning. Also referred to as the .25 Auto, the cartridge was introduced in 1905. The cartridge was a popular concealed carry caliber throughout the early 20th century. The debut of the cartridge came a few years after the .32 ACP was introduced and began legitimizing the idea of semi-automatic handguns. The cartridge was exceptionally popular in Europe after its introduction, leading to many firearms being produced in the caliber. Metrically, the cartridge is denoted as the 6.35 Browning.

Types of .25 Auto Loadings

• Full Metal Jacket (FMJ):Like the name suggests, these types of loadings feature projectiles which are adorned with metal jacketing. This jacket is generally made of copper and will cover the tip and sides of the projectile. Typically, the base of the projectile is left uncoated. These types of loadings are well-suited for range use and are some of the most common types of ammo one will encounter.

Firearms that Use .25 Auto Ammo

When it comes to acquiring firearms chambered in .25 ACP, one will encounter both vintage and recent production offerings. As far as vintage offerings go, one can encounter Colt Model 1908 Vest Pocket and FN M1905 pistols. Another notable firearm in .25 ACP would be the Raven Arms MP-25, an iconic “Saturday Night Special” which has been a common sight at pawn shops since its inception. Not many .25 ACP pistols are currently produced today. At the end of the day, if one did wish to acquire a firearm in .25 ACP, they will definitely be able to find something if they look hard enough.
