Hornady 380 Auto Cartridge Gauge

The Hornady 380 Auto Cartridge Gauge is a precision inspection tool designed for shooters, reloaders, and law enforcement professionals who prioritize ammunition quality and chamber compatibility. This gauge is essential for ensuring that every .380 ACP round meets safe firing specifications before it is chambered, thus preventing malfunctions and enhancing safety.

Constructed with a compact and durable design, the gauge operates on simple mechanical principles. It features a "go" end that allows properly dimensioned .380 ACP rounds to chamber smoothly, while an oversized or defective round will be rejected by the "no-go" end. This design eliminates the need for batteries or calibration, making it reliable in field conditions.

Law enforcement armorers, competitive shooters, and serious reloaders will find significant value in having a dedicated cartridge gauge in their maintenance kit. Hornady's engineering ensures that the gauge reflects actual .380 ACP chamber specifications found in quality production firearms, making it a trusted reference standard for quality control across various ammunition operations.
