The FLY 9 was developed with the same philosophy as the ULTRA series-- make a high-performance suppressor as light and compact as possible. The result is impressive, but requires some in depth discussion to really understand.

The FLY 9 is configurable in two lengths: Long and Short. Our "Long" length is shorter than everyone else's modular suppressor's "Long" configuration, but just as quiet (and often quieter) than the best in this class. Our Long configuration is lighter by at least 20%, in many cases 35% or even 50%, than other full-size 9mm suppressors. It weighs only 7.9 ounces in Long configuration, and that includes the booster, piston, and spring. Our "Long" configuration at 7.0 inches is the same length or shorter than many others' "Short" setups, but quieter.

In its "Short" configuration, it's simply shorter and lighter than anything else out there. Including the piston, it's at 4.4", which will typically add about 4.0" to the OAL of the pistol. It weighs only 5.5 ounces, and that includes a 17-4 steel piston (1/2-28 for weight reference). This is truly a "handy" length, and with "low-blast-subsonic" ammo such as "HUSH" or "STELTH", the muzzle and ear dB levels are under 140 dB!

To put it a different way, do you hate that 9mm cans almost always sound louder than you want them to? And that they're huge? This one will change your mind. At its "full size", it's only 7" long and adds about 6.6" to your OAL. In Short Mode, it's tiny.

The FLY 9 is rated for .300 Blackout SUPERSONIC ammunition from 8-inch and longer barrels, and .300 Blackout SUBSONIC ammunition from 5.5-inch barrels and longer. The FLY 9 is also rated for 350 LEGEND from 16" barrels and longer.

The FLY 9 is strong. Our test regimen was three 32-round Glock magazines fired from a select-fire subgun: the first two mags bursts, and the last mag full auto. We torture tested this for 30 cycles and the suppressor was perfect afterwards. After some consultation, we believe this exceeds all PCC/Subgun loadouts.

The FLY 9 ships with a 1/2-28 piston and a fixed barrel spacer (spring replacement). For high temperature durability, we are using specially-made 17-7 wave springs in the booster. It is compatible with the Rugged/Griffin/SilencerCo/TBAC standard pistons.
