The Sidewinder M2 features a significantly enhanced booster system that now utilizes the industry's unofficial standard piston for improved compatibility and ease of use. This innovative redesign allows for tool-free piston swaps thanks to a newly developed rear cap, simplifying maintenance and customization. The front cap has also been redesigned to optimize engagement with the takedown tool, further streamlining the service process. The Sidewinder M2 prioritizes user-serviceability, enabling easy removal of both the baffle and Nielsen device for thorough cleaning and maintenance using the provided disassembly tool. The integrated Nielsen piston ensures flawless semi-automatic operation on a wide range of host pistols. With 12 index points, the Sidewinder M2 allows for precise point-of-impact adjustments without the need to detach the suppressor from the firearm. When tested to Mil-Std 1474D on a Glock G21 using 230gr FMJ ammunition, the Sidewinder M2 .45 exhibits an average dry sound signature of 133 dB. "Wet" shooting techniques can further reduce noise levels, providing enhanced sound suppression for demanding applications. Can be used on .300 BLK SUBSONIC with a 7.5" or longer barrel.
