The .45 ACP is a favorite among semi-auto pistol shooters. The hard-hitting round delivers 400 to 500 ft./lbs. of energy with 200-plus-grain bullets while cruising below super sonic speeds. This also makes it an ideal candidate for a suppressor. As with all subsonic rounds, a shooter maximizes sound suppression when there is no super sonic sound signature. In other words, giggles and smiles for the shooter and people nearby!
For this test, we used a SIG SAUER P220 Elite chambered in .45 ACP and attached a Rugged Suppressors Obsidian 45 to the threaded barrel. The P220 is a great feeling gun without a suppressor, but the Obsidian made this pistol a blast to shoot with the added weight forward. Not only does the Obsidian reduce the sound signature as heard in the video, but it smooths out recoil, allowing the shooter to get back on target fast.
The Obsidian 45 is an extremely versatile suppressor. You can choose to run it in the full configuration: 8.6 inches long, weighing 12.8 ounces. Or, you can run it in the shorter configuration: 6.7 inches long, weighing 10.7 ounces. This is done via the ADAPT Modular Technology. You simply remove the thread cap and add or remove the extension tube and baffle that come standard with the silencer. You can also purchase a front cap in 9mm and various other pistons for different size threading, allowing you to take advantage of max sound suppression for multiple host guns while using the same suppressor.
The Obsidian 45 is a fully serviceable suppressor with a diameter of 1.37 inches. The baffles and mount are constructed of 17-4PH stainless steel and the tube is made of aluminum. The piston is non-slotted to reduce gas blowback common with slotted pistons.
The Obsidian 45 is rated for .45 ACP, 10mm, 9mm, .40 S&W, .22LR and subsonic .300 BLK rounds. While this suppressor is full-auto rated, it actually goes a step above with a belt-fed auto rating! The Obsidian 45 sells for $654 at SilencerShop.com.
