• Caliber: .25 NAA
    • Identical to the 32ACP frame, but chambered in proprietary 25NAA (a 32 bottle-neck cartridge)
  • Magazine Capacity: 6+1
  • Stainless Steel

Designed for law enforcement and people serious about personal protection, we think the results speak for themselves.  The .25 NAA is based on our very popular .32 ACP Guardian. Both are the same size and weight. The .25 NAA has a smaller barrel diameter to accommodate the smaller bullet. Like it’s larger cousin, the .32 NAA Guardian, the .25 NAA Guardian out performs many larger caliber guns. The bullet travels faster (1200 f.p.s.) and hits harder (20% more energy on average) than larger, 32 ACP caliber bullets. So, if you’re looking for a small, pocket gun that delivers the power of a .32 ACP with less recoil – you’ve found it! Contact your local dealer today to get your own .25 NAA Guardian pistol. Designed for people who are serious about personal protection.

Please note: The .25 NAA Guardian is nearly identical to our .32 ACP Guardian. They use the same parts (with the exception of the frame). Accessories, such as holsters and grips, designed for the .32 ACP will work with the .25 NAA as well. Because they have different frames, your .32 ACP can not be modified to work with .25 NAA ammunition.

The 25NAA is a new cartridge/firearm ‘system’ designed and developed by the partnership of North American Arms and Colorado Custom Cartridge.

In essence, the cartridge is based on a .32 case, which is necked-down to hold a smaller 25 bullet. The benefit is a remarkable gain in ballistic performance (below).

The .25NAA Guardian pistol is designed around this cartridge. This gun is almost identical to .32 ACP Guardian, different only in the chamber and the size of the bore. The cartridge is manufactured by Colorado Custom Cartridge, a well-recognized industry leader in the development of high-performance ammunition.

To summarize, the load delivers in excess of 1100 f.p.s. velocity to a 50 grain proprietary bullet from Hornady. This generates 134 ft. lbs of energy, specifically from the 2.5″ Guardian barrel (1453 f.p.s. & 287 ft. lbs from a 4″ test barrel).
