On 9mm, I feel the Cosmic was slightly quieter and deeper toned.

That’s just one man’s subjective opinion, though, and they’re so freaking close I’m more comfortable calling it a wash. If I were pressed, I’d give a slight nod to the Obsidian, which I think was just ever so slightly quieter though maybe ever so slightly higher pitched. Shooting the Obsidian45 back-to-back against my Cosmic, it was difficult to discern a sound level difference. Shoot it in full length on the range and when plinking with friends, and run it in K config for night stand use, PDW trunk gun use, etc. 458 SOCOM.īut if this is a dedicated pistol caliber can - and in RF’s case it will live on his B&T APC45 in K config or maybe on his FNX-45 Tactical when it isn’t temporarily on review guns - the modularity of the Obsidian is a big advantage. For me, it made up for that in caliber compatibility: the Cosmic is explicitly rated for at least 66 calibers all the way up to and including. There’s less weight at the muzzle end of the Cosmic, but the difference is minor when shooting.Īnd, of course, the Cosmic offers no shorter or lighter configuration option as does the Obsidian. Repaired, not replaced.Ĭompared to my Liberty Cosmic (two photos up), the Obsidian45 (above) in full length configuration is within a fraction of an inch of the same length (slightly shorter) and a fraction of an ounce of the same weight (slightly heavier). 338 Lapua SBR and pop the tube like a balloon, for instance, or run over it with your deuce and a half, Rugged can replace nearly every component on and it send it back to you with the same serial number. They were also smart to serialize the thickest, most durable, least likely to be damaged part of the suppressor. No warranty call needed - or even close - though Rugged actually does warranty stupid. 460 so don’t do this at home) ran smooth and suppressed great.

However, the GLOCK seen in the photos here is rocking a Lone Wolf slide (that camo pattern is laser engraved into the stainless steel slide, by the way) with a. Unfortunately I didn’t have a 5/8×24 piston to try it out. Thanks to those strong, sealed 17-4 baffles the Obsidian45 can also handle subsonic 300 Blackout. The Obsidian can also be shot “wet” - with a splash of water or other ablative, such as ultrasound gel, inside - for a temporary further sound reduction of somewhere around 5 dB. In K configuration, the numbers change to about 137.6 dB (.45 ACP) and 130.4 dB (9mm). It’s about 123.7 dB with 9mm, which is also a class-leading figure. 45 ACP or 9mm on a pistol.įull length - according to Rugged’s numbers - the Obsidian45 meters in at approximately 129.3 dB with. In any configuration you’re safely under the 140 dB impulse noise “hearing safe” threshold in. So depending on the caliber, application, and use you’ll be choosing between maximum suppression and minimum weight and size. Well, in every way except sound suppression. On a scale that’s 12.8 ounces versus 10.7 ounces. In its full length the Obsidian45 is 8.6 inches long, and in K configuration it’s 6.7 inches long. Then cap it off with the same front cap in either configuration. Employing Rugged’s “ADAPT” technology, a section at the muzzle end of the Obsidian can be added or removed quickly and easily as desired. The main reason to remove and re-install the front cap, though, isn’t for switching calibers but for switching the length of the Obsidian. However, that five-toothed gear pattern accepts the gear-shaped end of a booster piston, which can be used as a wrench if more leverage is needed. I found the front cap to be easily removed by hand. It may slightly cut down on sound volume when shooting the smaller diameter caliber. 45 front cap, but a cap bored for 9mm is also available. This is a much more cost-effective option for the owner than having to purchase a bunch of fixed mounts. For fixed barrels, a simple aluminum sleeve replaces the booster spring, locking the mount solid. The booster assembly makes swapping pistons easy, allowing the user to mount the Obsidian on different host firearms with different muzzle threading. This keeps the inside of the outer tube - the suppressor’s body - clean of carbon and other deposits and allows the baffle stack to simply drop out for cleaning and service. In the case of the Obsidian, its K baffles seal together and make a tube within a tube.
