DoubleTap 40 S&W 135gr JHP Home Defense Ammo - 20 Rounds/Box

DoubleTap 40 S&W 135gr JHP home defense ammo is engineered for responsible self-defense shooters who demand predictable performance in critical situations. This 20-round box delivers controlled expansion JHP bullets designed to balance stopping power with manageable penetration—a key consideration when your safety matters and innocent bystanders or family members may be nearby. The 135-grain load in .40 S&W is a proven choice for pistol shooters prioritizing defensive reliability over volume.

What sets this load apart is its ballistic discipline. In 10% gelatin testing, the projectiles expand to .68" while penetrating approximately 11.75", a window that maximizes energy transfer on target without the liability risk of over-penetration through walls or intermediate barriers. For home defense scenarios where shot placement and controlled bullet performance are equally critical, that balance matters. DoubleTap's quality control and component selection make this an ammunition choice you can trust when it counts.

Whether you're running drills at the range, qualifying with your carry gun, or building a home defense battery, this 40 S&W offering pairs well with modern compact and full-size pistols in that caliber. Twenty rounds per box means you get a practical quantity for training or ammunition staging without excessive bulk.

Frequently Asked Questions

Is DoubleTap 40 S&W suitable for home defense?

Yes. This round is specifically designed for home defense use. The 135-grain JHP load balances expansion and penetration to limit over-penetration while delivering effective stopping performance, making it a responsible choice for defensive scenarios where collateral risk is a concern.

What is the penetration depth, and why does it matter?

This load penetrates approximately 11.75" in 10% gelatin. Controlled penetration is important in home defense because excessive penetration can pass through walls or multiple barriers, risking harm to bystanders or family members. This round's 11.75" depth provides sufficient penetration for reliable terminal performance while reducing over-penetration liability.

How much does the bullet expand?

In 10% gelatin testing, these bullets expand to .68", which supports energy transfer and wound cavity development while maintaining structural integrity for predictable performance across varying target materials and distances.

How many rounds are in a box?

Each box contains 20 rounds, providing a practical quantity for training sessions, qualification drills, or home defense ammunition staging.
