Clear Impact Gun Accessories: 32 NAA Bottlenecked Cartridge

Published on February 1, 2017
Duration: 2:12

This video details the unique 32 NAA bottlenecked cartridge, developed in tandem with the North American Arms Guardian pistol. The cartridge's design allows for increased powder capacity, driving a smaller bullet at higher velocities. Ballistics testing in an FBI block demonstrated approximately 7 inches of penetration and significant bullet expansion, suggesting suitability for close-quarters defense without overpenetration.

Quick Summary

The 32 NAA cartridge is a bottlenecked design, formed by necking down a 380 ACP case to 32 caliber. This allows for a greater powder charge, enabling a smaller bullet to be driven at higher velocities, achieving approximately 200 ft-lbs of energy at 1,200 fps. Ballistic testing shows about 7 inches of penetration with significant bullet expansion, making it effective for close-quarters self-defense.

Frequently Asked Questions

What makes the 32 NAA cartridge unique?

The 32 NAA cartridge is unique because it's a bottlenecked design, created by necking down a 380 ACP case to a 32 caliber. This allows for a larger powder charge, driving a smaller bullet at higher velocities than typical for its size.

What are the typical ballistics of the 32 NAA cartridge?

Factory specifications for the 32 NAA cartridge, as fired from the North American Arms Guardian, indicate around 200 foot-pounds of energy and velocities of approximately 1,200 feet per second.

How does the 32 NAA perform in ballistic gel tests?

In FBI block testing, the 32 NAA cartridge demonstrated about 7 inches of penetration. The jacketed hollow point projectile expanded significantly, flattening out and losing some material, indicating effective energy transfer.

Is the 32 NAA Guardian suitable for self-defense?

Yes, the 32 NAA Guardian is considered suitable for close-quarters self-defense due to its cartridge's performance. The limited penetration (around 7-8 inches) reduces the risk of overpenetration, while the bullet expansion ensures significant energy transfer to the target.
