SilencerCo Omega 45K

The SilencerCo Omega 45K is the shortest full-strength 10mm can on the market at just 6.39 inches, and the best value once street pricing is factored in. It is a welded, tubeless design with a Stellite baffle stack, which means no serviceable tube but exceptional durability and a compact 10.7-ounce package. SilencerCo rates it for 9mm, .40 S&W, .357 SIG, 10mm, .45 ACP, .357 Magnum, .38 Special, .45 Long Colt, and .300 BLK sub and supersonic, so 10mm is an explicit factory listing.

The rear is SilencerCo's Alpha interface, so it runs the Alpha direct-thread mounts, Alpha pistons and the .45 3-lug mount. Match the part to the host: SilencerCo is explicit that the Alpha Direct Thread Mount must not be used on a pistol with an unlocking or moving barrel, so a tilting-barrel Glock 20 or 29 needs an Alpha piston with its spring and retainer, and a fixed-barrel PCC swaps that spring for the AC22 fixed barrel spacer. It is full-auto rated in a welded, tubeless package, so it trades user-serviceability for a sealed core. One caveat before you hunt one down: SilencerCo has sunsetted the Omega 45K, and what is left is dealer stock.
