Yankee Hill Machine Sidewinder M2 Direct Thread Suppressor
The Sidewinder M2 represents a thoughtful evolution in suppressor design, combining practical serviceability with genuine sound reduction. This .45 ACP suppressor delivers a 133 dB dry sound signature when tested to military standards on a Glock G21 with standard 230-grain ammunition—and shooting it wet yields even quieter results.
