Upon our arrival in Vegas for SHOT Show 2017, Sig Sauer was nice enough to host various members of the TTAG crew for the day at the Clark County shooting complex. Among the various products they had on display, I spotted their new and improved rimfire silencer.
Followers of the Sig universe will no doubt remember that Sig already has a rimfire silencer in the SRD22. That silencer used an aluminum tube, 17-4 stainless baffles, and was a somewhat porky 1.25 inches in diameter with the weight (7.7 oz) to go along.
The new and improved SRD22X sees a reduction in diameter down to 1 inch, small enough to clear standard iron sights on your favorite rimfire pistol. Sig has also moved to using a Grade 9 titanium outer tube. Both of these contribute to the SRD22 series shedding enough weight to get down to a hair over 5 oz. Initial metering tests indicate that the SRD22X comes in around 110 dB with subsonic ammo out of a sixteen inch rifle. Like its predecessor, the X model is still rated for .22 Win Mag and .17 HMR.
Sig has also moved to a shielded baffle stack system that they feel makes maintenance on dirty rifle cans quite a bit easier. The product manager I spoke with indicated that he’d recently gone 2000 rounds between cleanings, and easily pushed the entire stack out one end with his thumb upon disassembly. Speaking of, Sig includes the special wrench necessary to remove the end cap and the rear mounts. They also include both 1/2-28 and M9x.75mm end caps for your rimfire host of choice.
Out on the Clark County Range, I found the SRD22X to be a great companion for the rimfire pistols they had on display. There was little to no first round pop, and I had no problem shooting without my ear protection using standard velocity ammo.
The SRD22X is currently getting Form 3’d to dealers and will be listed at an MSRP of $495, $100 more than its predecessor.
