The SilencerCo Sparrow 22 on a Smith & Wesson M&P 22.

There’s not much more fun in recreational shooting than a .22 with a Silencer. Note I said “silencer” instead of “suppressor.”

While “suppressor” is a more technically accurate term, the original devices were named silencers. Maxim Silencers, in fact. Hiram Percy Maxim, not to be confused with his machine gun inventing dad, Hiram Stevens Maxim, is the guy whom most people believe invented the gun silencer. Not surprisingly, Hiram Percy also worked on early automobile mufflers as the basic principles are similar – taming hot and noisy gases after combustion.

For a long time, the industry drifted towards referring to “gun mufflers” as suppressors, but over the past few years I’ve noticed that most companies have gone back to the traditional name – silencers.

A few weeks ago, my BATFE Form 4, Application for Tax Paid Transfer and Registration of a Firearm came back from 10 months of hibernation on some faceless bureaucrat’s desk. Receipt of that precious document meant that I could pick up my SilencerCo Sparrow 22 Suppressor that was also in a 10 month deep sleep at my local FFL dealer. After dusting off the box and using carbon dating technology, I determined that it was, in fact, 10 months old. At least it’s new to me, right?

Let’s take a closer look at the SilencerCo Sparrow 22 and some gun and ammo options to go with it.

The SilencerCo Sparrow 22 Specs

Simply put, the SilencerCo Sparrow is a whole lot of fun in a small package. It measures just five inches long and a hair over one inch in diameter. Its total weight is just 6.5 ounces. It’s a rimfire design, although it is rated for the FN 5.7×28 centerfire cartridge. If you’ve got a .22LR, .22 Magnum, .17 HMR you’re in business. It will even handle .22LR in full-automatic operation if you’ve got such a thing.

For testing, but mainly just fun, I mounted the SilencerCo Sparrow 22 on two different guns: a Smith & Wesson M&P 22 pistol and a Colt / Umarex M4 Carbine chambered in .22LR. The Sparrow 22 comes with a standard 1/2×28 thread mount. Both guns required an adapter piece to mount the silencer. Some M&P 22’s models are available with threaded barrels, but the threads don’t extend past the slide. Adding a Tactical Innovations thread adapter and extender provided the proper mount for the Sparrow 22. The Colt Carbine also required a thread adapter to convert the standard barrel threads to the required 1/2×24 mount. With the adapters in place, mounting the SilencerCo Sparrow was a piece of cake – just screw it on until hand tight. While I did not encounter any loosening of the silencer, be sure to check once in a while to make sure it’s stills screwed on tight.

Here you can see the Tactical Innovations thread adapter on the pistol. Adding the Crimson Trace Laserguard turned out to be an "extra fun" bonus.

The Smith & Wesson M&P 22 with the SilencerCo Sparrow 22 was a beautiful combination. The MNP 22 is a full size 22 handgun, yet is very lightweight. Because the Sparrow 22 is only one inch in diameter, it did not interfere with the standard sights on this gun at all. I couldn’t leave well enough alone, so I added a Crimson Trace Rail Master with a green beam for improved daylight visibility. The Smith & Wesson M&P 22 has a standard rail, so this was an easy upgrade. Unless you’re opposed to giggling like a kindergartener, add a laser to your suppressed .22. Trust me.

Even though I was nowhere near bored with the pistol configuration, I moved the Sparrow to the Colt M4 Carbine 22. With its even higher iron sights, there was no issue with the silencer obstructing the sight picture. With the longer barrel, the rifle configuration was even quieter. Since I had to remove the muzzle brake, there was very little change in the overall length of the rifle with the Sparrow 22 attached.
