Another high quality offering from SilencerCo. I bought this can for my AP5 and it is the perfect can for such a small, handy PCC.
Collin C –
This is one of the best for dedicated use on a PCC.
Eric Hodera –
Had I known that the PISTON did not come with the silencer I WOULD HAVE NOT BOUGHT IT. So just like a lot of products out there, people cheat the consumer. I was told and saw proof that the Piston use to come with the silencer for your application of firearm when ordering but now you buy it separately so the company can make an extra buck. How sad this is. I haven’t been able to use the silencer yet as the piston I need is on back order. I wish I knew then what I know now…..a piece of useless metal junk until I buy the piston when it arrives. I shouldn’t have to pay $ 80 bucks that should have come complete in the box but now I know the truth, copie other companies to make money instead of a complete product, so much for buying American Made Product. If the piston doesn’t shot up before Christmas I’ll be returning the can. If you cannot use it why have an incomplete product.
Greg –
Short, light and quiet. Mounted on a FN 509 tactical. A terrific suppressor for your pistol. Highly recommended.
Greg –
This was a great choice for my FN 509 tactical. Not too heavy, quiet and all around solid suppressor. Highly recommend. This is my second SilencerCo can and I am very pleased.
Jason Hilton –
Great suppressor but does have the first round pop which is a good bit louder than my ab suppressor on my other 9mm.
Kenneth B –
Surprisingly quiet with regular ammo!!
Dan –
Don’t know waited 4 months due to incorrect paperwork done at kiosk. Just received it and still useless since I can’t get a 3 lug mount to use it it’s out of stock and EBS Arms said yes it’s hard to get. Should have never purchased this
Gregory W –
Great product. Not certain why everything costs so much but that is todays world
Steven K –
The product and the service, especially all the help on the forms, etc., by Steve was extraordinary. Thank you so much. I will definitely be back for more!
Charles W –
Very pleasant tone, and solid all around performance even in use with very short platforms. Very pleased with construction as well. I have experienced wear on the finish, in fact I noticed wear appearing very quickly after taking ownership. But all things considered, a very good product.
Mike W –
Excellent 9mm can, use it on my p226 legion and is very lightweight and easy to shoot with it on, hardly notice it affecting the handling of the firearm. It’s not the quietest can out there (my hybrid 46 does better at sound suppression but is like twice the size and a bit ridiculous on a pistol), but for its size and weight it is excellent. Finish and machinework is very nice and it feels very solid/well made. Would also make a great sub-gun can. I’d buy a second for dedicated subgun (mp5, stribog, other pcc etc) but will probably go with spectre 9 that just came out bc it’s lighter, relegate 9k to subgun and use spectre on pistol bc it’s lighter. But overall, really no regrets at all…
S. Miller –
Love the can… comes with the booster end cap with spring, as well as the direct thread option end cap. Doesn’t come with the piston however, which is probably my only con thus far. Bought the piston and attached it to a glock 19. Was curious if I would need to tune the pistol spring weight, but it ran great with the aftermarket 18 lb spring that I use normally. I bought it thru SilencerShop over the phone because I wanted to add it to my existing trust from them. Used the ATF eform method and had it in my hands in about 3 1/2 weeks after that phone call. Everything I’ve done previous to the eform took about a year each, so very happy with the expedited processing. I would recommend the can and SilencerShop to anyone in the market.. process is painless.
Ryan M –
Suppressor is great but the Suppressor shop and frontier justice slow things way down. Got a refund from frontier justice and went to another shop and bought there due to inefficient staff and it always being the ATFs fault. After a week of trying to certify my suppressor I got a refund. Went to another shop and by the time I got home it was certified and in process. So it’s frontier justice and/or suppressor shop that is complete shit. Will never go back to frontier justice for anything.
Will –
Best value for the price.
Jay Walker –
The silencer is exactly what I was looking for and installation was a breeze. It is a dream to shoot!
Bobby S –
This is an absolute beast of a can! I really love it, the overall size is amazing! Better yet the LITTLE CAN does an amazing job! I run mine on a Three lug dedicated can on a PCC, I have other 9mm cans that does not beat this one! Don’t let the “K” fool you!!
John K –
Purchased the omega 9k, put it on a ruger 9mm pcc. This is my first suppressor, it’s not a quiet as I was expecting when shooting super sonic ammo. Seems to be well built. I thought it was expensive, and I was disappointed that for the price, it doesn’t include the piston, for my glock 9mm pistol.
Kimberly G –
Quality product. Have purchased prior and fit the need for an additional purchase.
Moses K –
I would avoid the omega 9k. The quality control isn’t there. Reddit has several threads with bad welds. Reached out to CS and they basically said their welds suck.
Adam S –
Good can for a budget build. It’s not too expensive
Cory B –
A nice little compact can that is an awesome value for the price. Solid construction and looks nice mounted on my MP5K.
Spencer –
Excellent can
John H –
Another great suppressor from SilencerCo. Shot it indoors at the local range with super & sub sonics. Sound reduction is much better than I expected for such a short suppressor.
Highly recommend if you’re looking for a quality compact suppressor.
Andy –
Luv the quick three lug, And Merrimack Firearms are great. Helped me out big time!!!!! MP 5 clone and Subsonic 147 grain
Very quiet !
Jeffory R –
Works really well with subsonic ammo. Ran this on Glock 19, and Walther P22. Sounds like a pellet gun.
John R. Taylor –
Perfect in every way . Small , but quiet enough . Three lug adapter works without a flaw . Best value for the money !
Justin Z. –
Beefy can, durable construction. 2k rounds in 2 weeks it held up great.
Quick suggestion for anyone who switches platforms often, go get the SiCo Omni tool. The Piston Spring Retainer is made from Aluminum (why???), and the tool it came with do not work with that thing, you are gonna mar it up with a Knipex Cobra.
Lots of lube when installing the piston & spring, they get gunked up quickly.
Tyler F –
I was under the impression of it having ½ 28 threads it came with ⅝ threads. The ½ are out of stock . I can not use my product.. Not very happy. They won’t let me exchange new un used product.
Nicolas M –
Completely content. Great product.
Texas Life –
Silencer Shop is a very professional outfit. The assisted in the selection of this unit and the quality is amazing. Highly recommended Silencer Shop and this product.
Scotty A –
Picked this up along with the S Co 3 lug mount and adaptor for my KP9 SBR. Fits as it should, lock up is tight and is as quiet to be expected at the shooters ear with 115’s & 124’s
TOM M –
Extremely happy with performance weight and how aesthetically pleasing on my SP5
David C –
The Omega 9K is exactly what I expect a SilenceCo suppressor to be like. Great quality, easy to use and operate. Very little to no blow back which I feel is hard to find.
ROY S –
Lightweight.. very quiet great quality
Christopher K –
This was mounted on a CMMG Banshee 5”barrel in 9mm. For a short can it’s remarkably quiet. No malfunctions with three different types of ammo, one being Hornady sub sonic. I did experience quite a bit of gas blowback. At the end of a 33 round mag it was tough to see the target at 30m. (Indoor range) Accuracy was not affected at all.
Spencer P –
A classic & rugged. Works great for a variety of hosts! If you want “K” length for form factor you will see less performance than full-size cans. Perfect for FRT/SS equipped PCC’s.
Franko F –
This suppressor works awesome, very quiet with subs. Supers are also quiet. I put this on my Sig MPX K and it functioned flawlessly, but it’s very gassy in stock form. I’m dealing with it, but I might try an adjustable gas block down the road. But for now, I love the reliability.
