YHM is the leader in affordable, quality sound suppression. Each Sidewinder suppressor utilizes a Nielsen device to ensure 100 percent reliability on every handgun and is user serviceable. This means that your suppressor will never "fill up" from firing dirty or un-jacketed ammunition. Each suppressor includes the disassembly tool. Every sound suppressor YHM makes is full-auto rated and warranted for life from defects in material and workmanship.
