This is purpose-built ammunition for people who take their .357 Sig seriously. Double Tap's DT Tactical load pairs a 115-grain Barnes TAC-XP solid copper hollow point with flash-suppressed powder, delivering 1450 feet per second from a 4-inch barrel with 537 foot-pounds of energy. The result is a round designed to perform in defensive situations without compromising accuracy.
The Barnes TAC-XP bullet is the real story here. It's an all-copper construction with a large, deep hollow-point cavity engineered for consistent expansion and reliable penetration. Unlike traditional lead-core bullets, this design retains 100% of its weight through the target, meaning you get both controlled expansion and depth. The solid copper construction also makes it environmentally friendly while eliminating lead exposure entirely.
Double Tap engineered this load to balance velocity, power, and precision. The flash-suppressed powder keeps muzzle flash minimal, which matters in low-light defensive scenarios where keeping your night vision is critical. The 115-grain weight keeps recoil manageable compared to heavier .357 Sig offerings, making follow-up shots faster and more controlled.
Each round comes in a new, reloadable brass case with a boxer primer, so if you're into handloading, you've got quality components worth saving. The 20-round box contains full-power ammunition that cycles reliably in any modern .357 Sig firearm. This ammunition performs consistently across different barrel lengths, though a 3.5 to 5-inch barrel will deliver the best balance of velocity and terminal performance.
The Barnes TAC-XP is constructed entirely from copper rather than using a lead core with a jacket. This solid design retains 100% of its weight through the target while providing consistent, reliable expansion. The large, deep hollow-point cavity is engineered to prevent clogging with barrier materials like heavy clothing, and the bullet expands reliably across varying velocities.
Yes, Double Tap's DT Tactical load is safe to fire in any modern firearm chambered for .357 Sig. However, the ammunition is optimized for barrels between 3.5 and 5 inches. Always consult your firearm's manual if you have specific questions about ammunition compatibility.
In a defensive situation, especially in low-light conditions, muzzle flash can temporarily reduce your ability to see the threat and your surroundings. Double Tap's flash-suppressed powder reduces this problem, keeping your night vision intact and allowing for faster target reacquisition if needed.
Yes, these come in new, reloadable brass cases with boxer primers. Once fired, you can process and reload them using standard .357 Sig reloading procedures.
