Seismic 185gr 9mm: A Lot of Work for Nothing

Published on April 26, 2026
Duration: 15:02

This review of Seismic's 185gr 9mm Quake Maker ammunition, utilizing NAS3 cases, explores its performance claims centered on momentum. While the heavy projectile offers potential for barrier penetration, the reviewer found its velocity and energy metrics comparable to standard 147gr defensive rounds. The high cost and variability in performance due to the NAS3 case technology are noted drawbacks, suggesting it may not offer a significant advantage over existing, more affordable options for typical self-defense scenarios.

Quick Summary

Seismic 185gr 9mm Quake Maker ammunition focuses on momentum via a heavy projectile for barrier penetration. However, actual velocities average 850 ft/s with 297 ft-lb energy, comparable to standard 147gr rounds. At $1.90/round, it's significantly more expensive than typical defense ammo, and its performance benefits over cheaper alternatives are questionable for general self-defense.

Frequently Asked Questions

What is the primary performance claim of Seismic 185gr 9mm Quake Maker ammunition?

The primary performance claim of Seismic 185gr 9mm Quake Maker ammunition is its ability to leverage momentum over muzzle velocity. This is achieved through a heavier projectile, intended to provide enhanced barrier penetration and a more effective impact.

What are the reported velocities and energy metrics for Seismic 185gr 9mm ammunition?

Seismic advertises 900-1000 ft/s from a 4.5-inch barrel. Actual tests from a 4-inch barrel averaged 850 ft/s with about 297 ft-lb of muzzle energy. This is comparable to, or slightly less than, standard 147gr defensive rounds.

How does the cost of Seismic 185gr 9mm ammunition compare to standard defensive rounds?

Seismic 185gr 9mm ammunition is significantly more expensive, costing around $1.90 per round including shipping. Standard 147gr defensive hollow points typically range from $0.70 to $0.80 per round, making Seismic a much costlier option.

What are the potential drawbacks of Seismic 185gr 9mm ammunition?

Drawbacks include its high cost, potential velocity and pressure variability due to the NAS3 cases, and the fact that its performance metrics (momentum and energy) are often matched or exceeded by more affordable standard defensive 9mm rounds.
