Description
Double Tap built this load to fill a real gap in the 357 Sig market. For years, anyone serious about the caliber had basically one choice: standard 125-grain loads. This 115-grain option changes that game by bringing speed to the platform in a way most ammunition makers haven't bothered to pursue.
What Sets This 357 Sig 115gr Load Apart
The speed is the headline here. Out of a 4.5-inch barrel, this round hits 1612 FPS with 663 foot-pounds of muzzle energy. That's genuinely fast for this cartridge and carries real ballistic meaning. The controlled-expansion hollow point design is engineered to open reliably at those velocities without over-penetrating, which matters when precision matters.
Double Tap's flash-suppressed powder formulation keeps muzzle flash minimal, a practical feature when your eyes need to stay adjusted in low-light situations. The brass casing is reloadable, and the round functions reliably through 357 Sig pistols without feeding issues. This isn't exotic ammunition; it's straightforward, no-nonsense defense ammunition from a maker known for getting the details right.
115gr Versus 125gr: Why the Weight Matters
Lighter bullets generally mean flatter trajectory and faster velocity from the same barrel. The 115-grain projectile gives you a legitimate velocity advantage that translates to better expansion characteristics across a wider range of impact scenarios. If you've been running standard 125-grain loads and want to experiment with what higher velocity brings to terminal performance, this is worth trying.

Frequently Asked Questions
What's the actual velocity difference between this 115gr and Double Tap's 125gr loads?
Out of a 4.5-inch barrel, the 115-grain load runs 1612 FPS while the 125-grain runs around 1450 FPS. That's a meaningful velocity gap that affects how the hollow point performs on impact. Higher velocity can help ensure more reliable expansion, especially when barrier materials like clothing slow the bullet down.
Is this safe to use in a suppressor?
Yes. The flash-suppressed powder and subsonic-capable velocity data mean this round works well in suppressed applications. The reduced muzzle flash is a bonus in those situations where you're already running a suppressor.
Can I reload these brass casings?
Absolutely. The brass casings are reloadable, which many 357 Sig users appreciate. Make sure you follow proper reloading procedures for this pressure cartridge, and inspect casings for damage before processing.
How does 357 Sig compare to 9mm for defensive use?
The 357 Sig delivers roughly 250 FPS more velocity than standard 9mm with similar bullet weights, which helps with barrier penetration and more reliable expansion. You're trading magazine capacity and softer recoil for flatter trajectory and more energy. It's a trade-off, not a clear winner either way.
