Federal S40SJT2 Syntech Defense 40 S&W 175 gr SJHP50rd Box

Federal Syntech Defense 40 S&W ammunition delivers proven self-defense performance built on Federal's reputation for reliability and terminal consistency. This 175-grain load pairs a hollow-point bullet design with an advanced polymer jacket—the same Syntech technology that transformed range shooting now refined specifically for defensive carry. Whether you're stocking a duty weapon or a personal-protection handgun, Syntech Defense bridges the gap between range-proven reliability and field-tested stopping performance.

The bullet's engineering separates into distinct segments on impact: a deep-penetrating core backed by three heavy petals that each create independent wound channels. Federal designed this architecture to deliver the penetration depth critical in real-world scenarios—the core reaches 12 to 18 inches through bare ballistics gel and through heavy clothing layers. Those secondary petals extend 6 inches or deeper, multiplying the terminal effect without sacrificing the penetration consistency that defensive shooters demand.

Like all Syntech loads, the polymer jacket eliminates lead and copper fouling that accumulates in the barrel, reducing heat stress and friction during extended practice or duty cycles. The Catalyst primer—Federal's proprietary lead-free design—ignites with the consistency needed for reliable feeding and accuracy shot after shot. You get a round that performs on the range, cleans up after itself, and delivers when it matters.

Syntech Defense 40 S&W comes in 50-round boxes, sized for both serious shooters and those who practice regularly with their carry gun. If you run 40 S&W for self-defense, this is a round worth testing and trusting.

Frequently Asked Questions

What makes Syntech Defense different from other 40 S&W self-defense rounds?

The segmented hollow-point design separates into a heavy penetrating core and three petal sections that each produce separate wound channels. Federal engineered this to balance deep penetration through barriers with consistent terminal performance—the core reaches 12 to 18 inches, and the petals extend 6+ inches, multiplying the effect without sacrificing reliability.

Does Syntech Defense ammunition leave fouling in my barrel?

No. The polymer jacket eliminates lead and copper fouling, and the Catalyst primer is lead-free. This reduces heat buildup and barrel stress, especially during frequent practice or duty use.

Is Syntech Defense reliable for daily carry?

Yes. Federal's Catalyst lead-free primer provides consistent, hot ignition, and the ammunition is built to Federal's standard for reliability and function across 40 S&W platforms. As with all defensive ammunition, function-test your specific gun before relying on it for protection.

How much ammunition is in each box?
