SSK Firearms

Laying the Foundation

Before SSK Firearms was born, founder J.D. Jones began working with Contender® platforms, developing a lifelong passion for the ballistic performance of sporting, law enforcement, and military cartridges.

His early collaborations and innovations would later influence an entire industry.

SSK Industries is Founded

SSK Industries officially launches, focused on custom aftermarket Contender® barrels chambered in proprietary JDJ calibers-designed specifically for hunting.

These barrels quickly gained a reputation for unequalled accuracy  and big-game harvesting ability, cementing SSK’s position as a leader in handgun hunting.

Breakthrough Ammunition & Cartridges

• Development of the Whisper® family of cartridges, optimized for subsonic shooting and suppressed platforms.
• Collaborations on high-performance ammunition that set the standard for revolvers and auto-pistols worldwide.
• Introduction of legendary wildcat calibers, including the .950 JDJ, one of the most powerful sporting rifles ever produced.

Expanding the Platform

With the introduction of the Encore platform, SSK expanded into more powerful cartridges and custom builds for revolvers, bolt-action rifles, and other firearms, while maintaining its commitment to premium quality.

A New Era with Lehigh Defense

Lehigh Defense acquires SSK Industries, rebranding it as SSK Firearms.

The new chapter merges SSK’s tradition of craftsmanship with Lehigh’s manufacturing capacity and innovation in projectile technology, ensuring the brand continues to lead in performance and precision.
