KRISS USA

This is one of the products we brought to you from SHOT 2011 Range Day, and this video clears up a couple things I didn’t understand very well on the first look. Defiance is a new member of the KRISS family, makers of the KRISS submachinegun.
At some point I hope KRISS USA chooses to use native English speakers to explain this stuff instead of brilliant Swiss engineers fresh out of an ESL class, but because this was my second lesson on the Defiance technology I will go through the points he is trying to make in the video.
- There are two sizes of suppressors in the US made, Swiss engineered Defiance line right now. The shorter one is not entirely silent. He says it is so that the gun won’t hurt your ears, but more likely it is for law enforcement and military use where absolute silence is not required. It would also be for dispatching pest critters where it is legal and you don’t want to wake up the neighbors. The longer model is a complete silence option. I hope to get some of these for tests so we can show you on camera what is the difference.
- Feature #1 is a zeroing system built into the silencer. According to said brilliant Swiss engineer, this is a big issue with suppressors, not shooting to the point of aim that is normal for the gun. On this I will have to take his word, but if it is true, this is a pretty good feature. You can dial in the right point of impact by lining up the correct notch in that insert he shows you. I don’t know if it is a canting system or what, but he seems to feel it works very well.
- Feature #2 is a slide lock. Complete silence is only possible if you keep the gun from racking the next round, and with one twist, the Defiance suppressor does this. You have to rack the next round manually of course, but it gives you that first silent shot, and no brass to pick up. It sounds very covert.
I am just starting to familiarize myself with suppressors. If you don’t know this, it is legal for civilians to own suppressors in most states. You need to find a class 3 dealer and order what you want. He or she will then have you fill out a special BATFE form to apply for being licensed for one, and it is just an excuse for a $200 tax you have to pay for the application fee. If you have a clean record you will get your permit and be able to take your suppressor home within a few months. It is a lot to go through just for something that takes away the noise of your firearm, but they are kind of a nifty toy. I suggest you find a range that rents guns with suppressors to see if it is a big enough deal that you have to have one. But if you do, this Defiance seems like the cream of the crop. I don’t know what the price will be, but I’d say NOT CHEAP. Don’t worry you are worth it.
I would like to request a decal with your logo.

P7’s are gas-delayed blowback, not gas-operated.
No no no.
There is no “license” or “permit” for possessing an NFA Title II device. You pay a tax on the transfer, and you get a stamp. No ‘license’ as such. And it’s not an ‘application fee’. There’s no licensing procedure.
As someone writing a gun-related blog, you should take a second to research this stuff, and to present it accurately. It’s just like a 4473 being your ‘permit’ to possess any ordinary, Title I device like a handgun, rifle, or shotgun.
And there are plenty of gas-operated pistols. The HK P7 line, to name just one…from 30+ years ago.
The “slide-lock” likely disengages the LID, inducing a deliberate FTE.
Interesting.
Ok if you really want my take — you Lock open with a single shell and slightly drop the mag — gas pressure is not great enough to blow-back your receiver. Then you twist to ‘rack’ second load — this is done by taking your mag and inserting it all the way, this will allow you to manually eject the spent load and rack a second load, the the suppressor will let enough gas blow-back into your barrel to blow your slide open, eject the shell, and pick up a second round on the way forward. But really, what IS that tiny scar near the base of your skull, top of your spine? There really ARE physics beyond what we currently publish or understand. But you knowing about the use of quantum (THERE’S a funny word) leap and us being able to find you no matter where you are really IS unrelated to how the system works. Honest. I mean, REALLY! No connection at all!
I can’t see how turning a collar on a stand-alone suppressor could lock the action of the host pistol. The gas system of the pistol would still be in effect. The recoil of the projectile is still in play.
Maybe that was a specialized pistol platform, made specifically for their suppressors?
By locking out the impulse system, the anti-recoil attributes of the silencer [more effective than most muzzle brakes, in case you didn’t know] come into play. The only pistol I’m aware of that is gas-operated is the Desert Eagle: on that one, you’re right, it’s not going to lock out the action. All other semi-autos are recoil-operated [or blow-back, which again, this feature isn’t going to affect much if at all], and tugging on the front of the barrel is going to change things up.
Think of it as “machine-induced limp-wristing” if you can’t wrap your head around my poorly-worded description… đŸ˜‰
