Yankee Hill Machine Sidewinder M2 .45 ACP .578x28 Suppressor

The Yankee Hill Machine Sidewinder M2 is a lightweight suppressor for .45 ACP semi-automatic pistols, built with a mono-core baffle machined from 7075-T6 aluminum and a 6061-T6 aluminum outer tube, both with a hardcoat anodized finish. The piston, Nielsen device, and blast baffle are made from heat-treated 17-4PH stainless steel for corrosion and wear resistance.

The suppressor uses the industry's common piston standard, allowing cross-compatibility with pistons from other manufacturers, and a rear cap that permits tool-free piston swaps. Twelve index points allow point-of-impact adjustment without removing the suppressor from the firearm. The baffle and Nielsen device can be removed for cleaning and maintenance, and a takedown tool is included. The manufacturer's testing averaged 133 dB dry on a Glock G21 with 230-grain FMJ ammunition.
