The Double Tap Ammunition 40155X is a 40 S&W round loaded with a 155-grain projectile, engineered for shooters who demand reliable, consistent performance downrange. Whether you're training at the range, competing in speed events, or carrying a defensive load, this ammunition delivers the controlled expansion and terminal performance you'd expect from a serious ammunition maker.

Double Tap Ammunition has built a reputation among competitive shooters and serious enthusiasts for quality control and repeatability. The 155-grain weight in .40 S&W sits in the mid-range for the caliber, offering a balance of velocity, recoil management, and bullet construction. The hollow-point design is built to expand reliably across typical engagement distances, making this load suitable for both target work and defensive applications where expansion matters.
If you run a .40 S&W—whether it's a Glock 22, S&W M&P, or other platform—and you're looking for ammunition that performs consistently without the guesswork, Double Tap's straightforward approach to ammunition manufacturing speaks for itself. No hype, no shortcuts; just quality ammunition that goes where you point it.

This Double Tap round is loaded in standard .40 S&W, so it will chamber and fire in any firearm chambered for that caliber—Glocks (G22, G23, etc.), S&W M&P .40, Springfield XD .40, SIG P229, and similar platforms. Always verify your firearm's chambering before loading.
Yes. The 155-grain hollow-point load is designed to expand reliably, making it appropriate for defensive applications. However, your specific carry choice should align with your local laws and personal preference—test any defensive load thoroughly in your firearm before trusting it for carry.
Each purchase includes 50 rounds total, packaged as two boxes of 25 rounds each.
The 155-grain projectile is on the lighter end for .40 S&W, which typically ranges from 155 to 180 grains. A lighter bullet generally produces flatter trajectories and lower recoil impulse compared to heavier loads, making it popular for practice and competition shooting.
