Sig Sauer SRD22X, 22LR, 6.2″ Length, 1.0″ Diameter, Cerakote Finish, Black

The Sig SRD22X is the flagship of Sig’s rimfire suppressor lineup — a titanium .22 LR QD suppressor that represents the highest build quality available in the rimfire NFA category. Titanium construction keeps the SRD22X light on the muzzle of .22 pistols and rifles while delivering the sound reduction that makes the .22 rimfire + suppressor combination genuinely iconic: a platform that is hearing-safe, economical to shoot, and effective for pest control, training, and recreation at the same time. The Clutch-LOK QD system, carried over from Sig’s centerfire suppressor lineup, makes the SRD22X the most convenient QD .22 suppressor Sig makes — no tools, no cross-pin, no threads to hand-tighten. The included Shield suppressor cover manages heat for quick handling after shooting sessions. The ‘X’ designation indicates Sig’s second-generation SRD22 design with improved baffle geometry and wider compatibility with .22 LR hosts.

Why .22 LR + Suppressor Is Such a Special Combination

.22 LR with standard-velocity or subsonic ammunition is one of the few caliber/suppressor pairings that can achieve genuinely hearing-safe results (below 140 dB) without special hearing protection. Standard velocity .22 LR travels at approximately 1,050 fps — just subsonic — meaning there’s no supersonic crack, and the muzzle blast is already the quietest of any centerfire or rimfire cartridge commonly shot. Add a quality suppressor like the SRD22X and the combined noise signature is comparable to a staple gun: still audible, but no longer capable of causing hearing damage at normal shooting distances. This makes the suppressed .22 LR a uniquely valuable tool for training new shooters, pest control without disturbing neighbors, and extended range sessions where hearing protection fatigue is a real concern.

FAQ — Sig SRD22X

Is the SRD22X user-serviceable?

Yes — like most .22 rimfire suppressors, the SRD22X is user-disassemblable for cleaning. .22 LR produces heavy lead fouling that builds up faster than centerfire calibers; periodic cleaning (every 500–1,000 rounds) maintains peak sound reduction. Disassembly instructions are included. Do not run the SRD22X through an ultrasonic cleaner without consulting the Sig owner’s manual.

What .22 hosts is the SRD22X compatible with?

Any .22 LR host with 1/2×28 muzzle threading: Sig P322, Walther P22 threaded, Ruger Mark IV Tactical, S&W Victory, Browning Buck Mark, Ruger 10/22 threaded barrel, and most threaded .22 rifles. Call Western Sport at 817-393-4000 to confirm your specific host’s compatibility.

Why is the SRD22X an NFA item even though .22 LR is inexpensive?

All suppressors, regardless of caliber, are regulated under the 1934 National Firearms Act. The SRD22X is a federal NFA suppressor item — Form 4 transfer, background check, and $0 stamp (OBBBA applies). The low cost of .22 LR ammunition makes the suppressed .22 one of the most economical NFA use cases available once you have the can in hand.
