Yankee Hill Machine Sidewinder M2 9mm Suppressor – 1/2″‑28 Steel, 8.35″ Length, 10.15 oz, Black

The Yankee Hill Machine (YHM) Sidewinder M2 is a high-performance, user-serviceable suppressor engineered for 9mm pistols and carbines. Its mono-core 7075‑T6 aluminum design delivers crisp suppression with minimal blowback. Weighing just 10.15 oz and measuring 8.35" (length with piston), it offers exceptional handling without bulk

A tool-free booster piston system ensures compatibility with SilencerCo, Rugged, and Dead Air pistons, while 12 indexing positions allow you to fine-tune your point of impact under mount. The suppressor is constructed from 6061-T6 aircraft aluminum and 17-4 stainless steel, with Type III hardcoat anodized matte black finish for maximum durability

In sound tests, the Sidewinder M2 registers around 125 dB dry on a Glock 17 with 147 gr rounds—and can drop lower when used “wet” for additional suppression . Full-auto rated, easy to disassemble, and built for longevity, it's a top-tier suppressor choice.
