YHM Sidewinder M2 .45 ACP Suppressor – Direct Thread, Aluminum/Steel, 133 dB

The YHM Sidewinder M2 is a full-featured, user-serviceable .45 ACP suppressor engineered for reliable performance on semi-automatic pistols and compatible platforms. Featuring a completely redesigned booster system, the Sidewinder M2 now incorporates the industry’s unofficial standard piston format and a new rear cap that allows tool-free piston swaps for fast, hassle-free maintenance in the field. The redesigned front cap improves engagement with the takedown tool, making routine service straightforward and efficient.

Built from aircraft-quality aluminum and 17-4 PH stainless steel, this suppressor offers a durable, corrosion-resistant construction with a full-auto rating. YHM’s integrated Nielsen device (piston) ensures flawless semi-automatic cycling on all relevant host pistols, while 12 index points allow precise point-of-impact adjustment without removing the suppressor from the host firearm.

Tested to Mil-Std 1474D, the Sidewinder M2 delivers an average dry sound signature of 133 dB on a Glock G21 using 230gr. FMJ ammunition — with even quieter performance when used wet. The suppressor is also compatible with .300 Blackout subsonic loads when used with a barrel of 7.5″ or longer.
