Frequently Asked Questions

What are the key differences between Doubletap Ammunition's 77gr, 115gr +P, and 124gr +P 9mm loads for self-defense?

The 77gr load is hyper-velocity (1600 FPS) with low penetration, ideal for urban home defense. The 115gr +P lead-free hollow point offers more penetration and bone-shattering power. The 124gr +P controlled expansion load also provides significant penetration and immediate expansion upon impact.

Which Doubletap 9mm load is recommended for urban home defense and why?

The 77-grain Doubletap 9mm load is recommended for urban home defense due to its hyper-velocity (1600 FPS) and exceptionally low penetration. It demonstrated excellent energy dump by breaking ribs and stopping within the target, minimizing the risk of over-penetration in confined spaces.

How does the bullet construction of Doubletap's 115-grain +P 9mm round affect its performance?

The 115-grain +P round features a solid copper hollow point construction with a core separated from the jacket and pre-cut edges. This design promotes rapid expansion, leading to significant tissue damage and bone pulverization, though it results in slightly more penetration than lighter, faster rounds.

What tactical advantage does mixing ammunition types in a defensive magazine offer?

Mixing ammunition types, such as placing 77-grain rounds first followed by 115-grain or 124-grain rounds, offers layered defensive capabilities. This strategy allows for reduced over-penetration with the initial shots in urban environments, while subsequent rounds provide increased penetration if necessary.
