The 4.1" handgun and 20" bolt-action hosts used for the 9mm sweep

How to read this report

Our core performance metric is LIAeq100ms: the whole pressure curve, A-weighted to approximate the human ear, integrated over 100 ms. Peak and impulse are shown alongside for context. Every configuration is metered at SE (shooter's ear) and ML (muzzle, left side).

Sound metering methodology

About the Test Platform

Same 4.1" handgun, two loads that behave nothing alike. Federal 115gr Champion is bulk range ammo and leaves the muzzle supersonic, so part of what you hear is a crack the suppressor cannot touch. Federal Syntech 147gr stays subsonic out of the same barrel, which is where a 9mm can does its best work.

The gap between those two columns is the ammunition, not the suppressor — worth knowing before you compare a number quoted on one load against a number quoted on the other.

The last column is a 20" bolt action running 7.62x51 Lake City M80, the same host and same reference cartridge as the 7.62 battery. Plenty of 9mm cans are rated well past pistol calibers, and testing them on the rifle bench means those numbers read directly against every 7.62 suppressor we have metered.

The handgun and bolt-gun hosts behind our 9mm tests — write-up not yet published.

Cold-can first shot

First round pop

On the first shot, unburnt propellant mixes with the oxygen sitting inside the suppressor and burns a second time in the can. That secondary combustion often makes the round louder than the ones behind it. Once that oxygen is burnt off, follow-up shots settle into a quieter, steadier number. This is commonly called first round pop, or FRP. Because a hunter, marksman or defensive shooter may only ever fire one or two rounds, we isolate the first-round data rather than bury it in the average, and present it here. The magnitude of first round pop varies substantially across designs.
