Yeah, that's how long it took to get my tax stamp from when I paid for it. Griffin Armament Checkmate QD.



I decided to get a rimfire can because I have a pistol can (Silencerco Osprey .45), and a rifle can (Silencerco Omega). I think this will be a lot of fun.

This one is a newer model that has the stainless monocore baffle instead of a bunch of K baffles. Hopefully that will make it easier to clean.

It came with one 3 lug mount, so I decided to order another, which I've had for almost a year, and a direct thread mount that I bought maybe a month ago. The two 3 lug mounts are going on the Buck Mark pictured above, and a Ruger 10/22 Takedown.



I really like how small the rimfire cans are. I don't have to buy any special sights for them to work on my guns.

This should be a fun little gadget, and I'm looking forward to some range time with it.

    Do we forget that cops were primarily still using 6 Shot Revolvers well through the mid 80's? It wasn't until after 1986 that most departments then relented and went to autos.
    Capacity wasn't really an issue then... and honestly really it's not even an issue now.
    Ray Chapman, used to say that the 125-grain Magnum load’s almost magical stopping power was the only reason to load .357 instead of .38 Special +P ammunition into a fighting revolver chambered for the Magnum round. I agree. - Massad Ayoob

    Paradoxically it is those who strive for self-reliance, who remain vigilant and ready to help others.

    Info from manufacturer

    It weighs in at 5.3oz, 5.95" long, and 1" in diameter. It's a small little guy, but it's sound reduction is impressive. I wish we could have had the range to ourselves so we could take off our ear protection, but there was always at least a couple people around us shooting.

    A friend and I took it to the range today to test it out. We shot somewhere around 200-250 rounds of Remington Thunderbolts. I'm not a big fan of this ammo, as it seems to be more dirty than other .22 ammo I've shot, and I've had more jams with it than other brands as well. Though, it did shoot really well today. We did have some hiccups at the end where the gun was jamming. That was the dirt gumming up the firearm from the dirty ammo, and the suppressor throwing a bunch of crud back into the gun. I could feel that the slide wasn't moving as easily as it usually does, and the face of the slide was really, really dirty. After it started jamming, we decided to stop shooting and head home.

    I brought the Silencerco Osprey along with the Springfield Armory threaded XDM in 9mm to see how they did next to each other. The Checkmate with the .22lr ammo was definitely more quiet. Not too much of a shock, but it was still noticeable even with muffs and ear plugs on. For those of you wondering why we had those on, you can read back near the beginning where other people were shooting near us. We were the only lane with suppressors, and one guy in the next lane was rattling off a bunch of .223. Not too quiet at an indoor range.

    The Checkmate QD, at least the newer version like this one is, has a monocore baffle instead of the normal K baffles like a lot of other cans have. It comes with a 3 lug QD system that is really nice and easy to attach and detach the suppressor from. There is the 3 lug mount that you screw onto your gun, and then you push the suppressor on, and twist it a bit until it locks on. Anyone familiar with the MP5 3 lug will know how it works.

    It is pretty easy to take apart. The front end cap just unscrews with your hand. That's a good thing and a bad thing. It does really easily come off, even after shooting the amount of ammo we did through it. But the down side is that it slowly unscrews while you shoot. Not a major deal as long as you check it and make sure it stays put. I didn't notice it until I was getting a big impact shift. First I noticed that my mount was unscrewing, so I tightened that up. I'm going to use some blue thread locker on it after it's cleaned up. After that it still had a POI (point of impact) shift, so I checked the end cap, and it has unscrewed a little bit. Nothing to be worried about, but it did in fact change the POI. Once it was screwed back on, it worked fine.

    It was a lot of fun shooting with it. We did take a couple shots with the suppressor off to see the difference, and it was pretty significant. I realize that .22lr isn't really a loud round compared to others, but it was cool trying out this little can.

    So the only things that were kind of annoying can easily be fixed. A bit of thread locker on the mount, and keep an eye on the end cap.
