Suppressor on rimfire semiauto?

I won a SilencerCo 22 Sparrow suppressor in a raffle; will it just screw onto a pistol with threaded barrel and be functional, or do .22s usually need some "tuning", like different spring rates, to run reliably with a suppressor?
I've watched some vids on the sparrow, and on suppressed rimfire pistols, but still not sure if the Sparrow will work with a pistol?

It should allow a semi-auto pistol to work fine, since all .22 auto pistol barrels that I'm aware of are stationary. I've only gotten into things like reciprocating pistons and springs with locked-breech pistols such as Glock, HK USP, 1911, etc.

Excellent point, ether.
Bersa has a fixed barrel, so no problem.
I've heard of Browning 1911-22s with threaded barrels, and lots of ads for "suppressor ready" versions.
But never seen a suppressor on one. Just "flash hiders".

Same with the S&W and Walther 22s - fixed barrels.

I have been running my oldest on the Walther p 22, about 20 years, never a problem. I have been running on the Glock 44 since that gun came out, never a problem and close to dozen total with the rimfire suppressors. See my post below. Polish the chamber because the can pushes crud back into the action and chamber, and keep it lubed, no problems at all if you do that. None.

Since they get dirty quicker, faster ammo will worker longer, Stingers are best but any CCI or others over 1,200 fps will run 100s or rounds. The Quiet loads, 710 fps often will not cycle the gun with or without the suppressor, so they are single shot guns. No problem really because when the action does not open, the are more quiet, it you want that.

As others have said, it will probably work just fine. My YHM Stinger lives mostly on my CZ these days but I use it on my Ruger 22/45 pistol as well. Never had an issue at all. My CZ rifle is movie quite. The loudest thing you hear when shooting is the hammer hitting the firing pin. It's annoyingly louder then the report of the cartridge.. Lol

No tuning is needed as the majority of 22 pistols have fixed barrels.

The only 22s that I dont shoot suppressed are revolvers. If I could suppress them I would.

I have an Osprey SS that I used on everything before I got a Thunderbeast TakeDown. Now the Osprey lives on a 5 inch full auto M-16 upper.

I just picked up a Dead Air Mask suppressor, runs great on my 10/22 and my Ruger Mk III.
Again the pistol has a fixed barrel, so zero issues with the gun running well.
Make sure you use standard velocity .22 LR, the effect is not nearly as impressive with High Velocity or Hyper Velocity .22

No, no, no and no. You need nothing whatsoever. I run 2 suppressors of totally different design on a dozen rimfire handguns. Like any 1911 or semi auto pistol, unless you limp wrist it, it will fire 100% with full power ammo. Optics do Not affect it unless they are heavy, then, maybe. Stingers give the best slide speed if that is an issue.

If you shoot the very slow ammo, 710 fps or 850 fps, sometimes they are too slow to work the slide, so keep it clean and lubed.

On all rimfire pistols, polish the chamber, I use Flex Hones, and touch it up every 500 rounds or so and you can never have an issue.

I shoot most of those mentioned above, the Glock 44, Walther PPK/s 22, 1911-22, Walther P 22, Ruger Charger, Firefly and others plus the 1022 and even the 22 mag, 17 HMR and 17 WSM all with those same 2 suppressors.

You do not need to do anything different, except polish the chamber because the suppressors blow more crud back into the chamber and they get dirty quicker, and keep them lubed.


Buy lots of spare magazines, so you do not have to reload at the range.

I don't even have to think about my suppressed .22 semi-auto. Ruger MKIII. It's integrally suppressed. Looks like a normal bull barrel Ruger but silent! TBA Suppressors in Ashland, Virginia makes the best integrally suppressed firearms. I have a few of his.

I have a supressor and a Vortex dot sight, and want to put them both on the same gun.
At this point, my only requirements are threaded barrel, and pre-cut for the optic; suggestions?

Older guys will remember when cars and trucks had large 1 qt oil filters around 8" long, with about a 4" diameter. A couple days ago I watched an older Hickok45 video where we was shooting a .22 auto pistol with an old style oil filter attached. It was quiet. The video didn't show how it was attached. I assume it was threaded on.

I have several.22 cans and three different.22 pistols. I had to buy thread adapter for one (duh) but nothing else. All are fixed barrels, which i think is typical in 22 pistols.
my favorite is a Sig (GSG) 1911.

CCI standard is effectively subsonic in most pistols so its berry berry quiet!
The powder charge in 22 is so minuscule I don’t think it will require altering components.
go out and sling some lead.

ps when it gets gunked up, breakthrough’s suppressor cleaner works well to clean these cans.

A local guy just suggested a Kel-Tec with threaded barrel and already cut for the optic, for well under $200. :oops:

I had an issue with my Sparrow on my 1st gen M&P 15-22. It would not group with any ammo i had, including CCI Standard Velocity. I talked to Silencerco, they sent me an adapter, and I sent them numerous measurements. I got nowhere with them. I noticed the suppressor o-ring wasn't reaching the end of the barrel. They assumed it had to be the barrel. I ended up taking the rifle and Sparrow to the LGS i bought Sparrow from, and one of the guys with a lot of suppressor experience took it home and ran it. He removed the o-ring from the suppressor, where it threads on the barrel, and it started grouping as expected. Prior to that, I would zero the rifle with a Vortex rim fire scope, then put on the suppressor and the groups would be off right 12 inches and down 5-6 inches. Adjusting to it didn't help since the groups were horrible. Never had a suppressor strike of anything like that. If I had to do it over again, I'd say to heck with it, just put on ears.

Buds Gun shop. This one or the Ruger gives you both range play and squirrel defense capability. I am not a fan of the Buckmark but respect their accuracy and as a hunter, I might buy this one, if I did not otherwise have that square filled. I assume you can find one without the CT optic on that one.

If you would consider stepping up and out of the box, that suppressor and optic will greatly enhance anything a 22 can do and extend the actual and practical range beyond 100 yards. And if hunting, it makes all the difference in the world.

I have the M and P 5.7 x 28, that I use either of my suppressors on. I have the Vortex RFX 15 GREEN dot sight on it and a cheap laser on the rail below. Ammo is $20-$22 box for Fiocci, a 40 grain bullet about 1,800 fps. The gun holds 23 rounds and has zero recoil. About as accurate as a handgun can be. Your suppressor and can would be on that gun and running it 15 minutes, tops.

M&P® 5.7 WITH THUMB SAFETY | Smith & Wesson

Probably about the lightest handiest and most accurate handgun on the market today, especially with the 5.7 x 28 features. Basically if hunting about the same as a 22 mag rifle at distance.

I also have the SW M and P in 22 mag, almost identical gun except is it not threaded for the suppressor, but works great with a dot sight. That one holds 30 rounds in the mags and fires as fast as you can fire, 100% with every ammo I have tried, just saying, my experience with this new floating barrel type system in the 2 calibers is 100%. Pretty rare these days to find any gun that is 100, lol.

My use for these is range fun, and walking, riding around in the boonies, they are open carry along with my EDC gun of the day. I am not a fan of dot sights on carry guns, but they are a miracle worker on these.

Just saying, as an old gun gun, these work.

Only matters one game I suppose but studies have shown that a deer can hear bolt action chamber a round on a cold morning at a half mile. I am pretty much into noise discipline when shooting suppressed, comes from my life in the military I guess. So, it carries over to coyote hunting or any time I shoot game.


On the 1022 and the Charger, the pistol version with the 10 inch barrel, I use those little magnets to hold the chamber shut, OR you can just hold it shut with your thumb and you do not get all that clack noise from the action slamming shut. That matters if you have more than one critter and hidden from view.

When shooting handguns like the Glock 19 suppressed I just hold the action closed with my thumb on the back of the slide, simple deal and keeps the noise down.

The ability of some of these guns, like the Ruger when suppressed is amazing. I have Hollywood quiet 22s down into the 70 db range. Makes for some might fine shooting days, when your BB gun is loud and your 22 is not.

Enjoy. Hopefully suppressors will not be regulated or so expensive next year and kids can make them in shop class at high school.

Think about that one. Freedom and hearing aid companies will decline dramatically.
