ASP (Armament Systems and Procedures) specializes in tactical self-defense tools and restraint equipment, with a focus on law enforcement and professional security use. Their product line centers on expandable batons in various configurations and lengths, along with duty-grade cases and holsters designed for secure carry and quick deployment.

Beyond batons, ASP offers a range of carrying solutions including cuff cases, scabbards, and specialized holsters engineered for professional environments.
