Frequently Asked Questions
How does the DoubleTap 135gr JHP perform compared to heavier .40 S&W loads?
The 135gr bullet travels significantly faster than heavier 155gr or 180gr .40 S&W loads, generating a flatter trajectory and rapid energy transfer. Its lighter weight at higher velocity allows the Controlled Expansion™ hollow point to open quickly and reliably, producing a wider wound channel. The trade-off is slightly less penetration depth than heavier rounds, but at 11.75" in ballistic gelatin, it sits comfortably within the FBI's recommended 12–18" penetration window for defensive use.
Is this ammunition compatible with my .40 S&W pistol?
Yes — this load is compatible with any standard .40 S&W chambered semi-automatic pistol, including popular models from Glock, Smith & Wesson, Sig Sauer, Springfield Armory, and others. As with any new defensive load, it's recommended to fire a box through your specific firearm to confirm reliable feeding and cycling before carrying it for personal protection.
Can I use this load for range practice as well as home defense?
While DoubleTap's 135gr JHP is optimized for defensive use, you can absolutely run it at the range to verify point-of-impact and test reliability in your firearm. However, for high-volume training sessions, a comparable full-metal-jacket practice load will be more cost-effective. Many shooters use a box or two of this JHP to confirm function and zero, then reserve the remainder for carry or home defense duty.
