Liberty Suppressors Announces the Cosmic 45 Multi-Caliber Pistol Can

Hot on the heels of other new releases like the Leonidas Ti, Liberty Suppressors has announced the release of their latest suppressor, the Cosmic 45. In line with other recent releases from other companies, the Cosmic is designed to be a multi-caliber can rated for just about every caliber from 22LR to the powerful 454 Casul.

The can comes in at a scant 9.5 ounces using a combination of a titanium tube and a stainless steel baffle core.  The can fits “the same footprint” as their Mystic X cans and has full backwards compatibility with all the various mounting systems including sub-machine gun mounts, tri-lug mounts, boosters, pistons, and direct thread adapters (or you can build your own can like Pete did here). The suppressor module is 8″ long and is finished in a black high-temperature resistance Cerakote.


Liberty lists an impressive amount of calibers that can be shot through the can, including 10mm Magum, 10mm Auto, and both .458 Socom and .450 Bushmaster (though Liberty advises that the carbine rounds may not come in below 140 dB – where gunshots are considered “hearing safe”). Liberty rates the can at 134 dB using standard 45 ACP rounds.

Those interested in the can can learn more direct from Liberty Suppressors on their website or check out the video with their President below. Retail is pegged at $799.

    I really hope those “standard” .45 acp rounds are supersonic, otherwise that’s a bad suppressor.

    • ostiariusalpha

      Could be. Judging the effectiveness of a suppressor from an audio track is a bit futile. You really either need to be there or, better yet, have a correctly calibrated impulse sound meter take the measure of multiple shots like the Military Arms Channel did on several videos.

      • iksnilol

        I wasn’t judging it from the video, I was judging from the text that claimed 134 db with standard .45 acp rounds.

        • ostiariusalpha

          134 dB is pretty standard for a .45 suppressor in the real world. For instance, SilencerCo claims that the 9mm Osprey reduces sound to 127 dB, yet during MAC’s testing it was more like 132 dB. Seems like Liberty is being a bit more honest.

          • iksnilol

            I am used to quieter with subsonics and you can argue that “standard” .45 acp is subsonic.

          • ostiariusalpha

            The suppressor only moderates the noise of the explosive ignition of the propellant; the velocity of the projectile (and whether it produces a supersonic crack) is outside of this function. Standard subsonic .45 ACP is generally just as loud as supersonic 9mm at the point that the suppressor effects.

          • iksnilol

            Yes, but the sound meters do pick up on the noise of the bullet if the meters are 1 meter to the front of the gun (which is how standard testing is done IIRC).

            I mean, just take a suppressed .22 LR and sound test it with supersonics and subs, you’ll see that the supersonic ones meter higher than the subsonic ones.

          • ostiariusalpha

            Right, with the sonic crack factored in, 9mm is around 159 dB, standard subsonic .45 is about 157 dB, and subsonic 9mm is approximately 152 dB. A subsonic loading in a supersonic cartridge isn’t just lacking the crack, but is also a less powerful explosion. The .45 is a good sized cartridge, pushing a relatively heavy bullet, so it’s no surprise that it makes a nice, loud bang.

          • Indiana Mike

            There is no doubt that .45 ACP 230 Gr. Ball is subsonic.

  • Cymond

    Personally, I’m a 9mm kind of guy, so I would still go with the Mystic-X.

    Anyone interested in multi-caliber suppressors should also look at the Griffin Armament Optimus, and maybe wait until we know more about the SilencerCo Hybrid.
    This seems like a growing market segment.
