For decades, a go-to caliber for pocket pistols was the diminutive 25 Auto, which was small enough to fit in classic "Vest Pocket" models of the early 20th century and was more reliable than rimfire, thanks to its centerfire primer. Hornady takes this defensive round into the 21st century with its Critical Defense load in 25 Auto. The defense-oriented construction of the Hornady Critical Defense round can be found in several key elements of the design. Nickel-plated cartridges allow users to easily chamber-check the gun in low light, and the smooth finish aids in lubricity and feeding. The cartridges are also loaded with low-flash powder to avoid blinding shooters in low-light self-defense situations.

• Bullet weight: 35 grains
• Muzzle velocity: 900 fps
• Muzzle energy: 63 foot-pounds
• Ships in quantities of 25 rounds

Each Critical Defense 25 Auto round is topped with the company's FTX bullet design, which helps to prevent clogging when shot through heavy clothing.
