What Is the BANISH 9K? (The 2.7 oz, 4.1″ Titanium Answer)
The BANISH 9K is a 3D-printed titanium 9mm pistol suppressor built by BANISH Suppressors. It weighs 2.7 oz, measures 4.1 inches in overall length, and is rated for 9mm Luger.380 Auto, 5.7x28mm, and.300 Blackout in subsonic loads. It uses a direct-thread mount so it runs reliably on tilting-barrel handguns like the Glock 19, SIG P320, and Springfield Hellcat Pro OSP, as well as on pistol-caliber carbines and subsonic.300 BLK AR pistols.
Additive manufacturing is what makes the 9K’s spec sheet possible. Printing the baffle stack in titanium lets BANISH build internal geometry that would be impractical or impossible to machine from solid stock, which is how you get a 9mm can that’s closer to the weight of a loaded magazine than to the weight of the pistol itself.

How Quiet Is the BANISH 9K?
The 9K is a hearing-safe pistol can on standard 9mm pressure. Real-world impression from the reviewer circuit is “backyard-friendly on a 9mm pistol” — soft enough that you notice the action cycling more than the muzzle report. For a suppressor this short and light, that kind of sound reduction is the whole selling point: a can you’ll actually leave mounted on a carry host or PCC.
- Concealed-carry and home-defense pistol owners — 2.7 oz changes how your Glock 19 or SIG P320 points less than almost any other 9mm can.
- 9mm pistol-caliber carbine shooters — the 4.1″ length keeps AR9s and MP5-style builds holster-short by carbine standards.
- .300 Blackout AR pistol builders running subsonic loads who want the most compact dedicated-subsonic setup they can own.
- First-time suppressor owners who want one can that covers most of their pistol-caliber safe and doesn’t punish them on the scale.
Every can in this class is a strong choice — the right one depends on the host and the mission.
- BANISH 9K is best for shooters who prize the lightest, shortest titanium 9mm can they can bolt to a carry pistol, PCC, or subsonic.300 BLK AR pistol.
- SilencerCo Omega 9K is best for shooters who want a widely-supported mount ecosystem and a proven all-purpose modular 9mm can.
- Rugged Obsidian 9 is best for shooters who want a modular, user-serviceable can that converts from short-K to full-length on the same host.
- Dead Air Wolfman is best for shooters who want a full-auto-rated 9mm can with a big host list and willingness to trade weight for durability.

$0 Tax Stamp in 2026: What Actually Changed
The $200 NFA transfer tax on suppressors was eliminated on January 1, 2026 by the One Big Beautiful Bill Act (OBBBA). The ATF still regulates suppressor transfers: you’ll still file an ATF Form 4, still pass a background check, and still submit fingerprints. The change is that qualifying suppressor transfers no longer carry a $200 federal tax.
Frequently Asked Questions
The 2.7 oz weight and 4.1 inch length are class-leading, and the 3D-printed titanium construction keeps the can tough without turning the host into a different gun.
How quiet is the BANISH 9K?
The 9K is hearing-safe on standard 9mm pressure loads and soft enough that on a handgun host the action cycling is often more audible than the muzzle report. For a can this short and light, that kind of sound reduction is the whole reason to buy it.
What calibers does the BANISH 9K work with?
The BANISH 9K is rated for 9mm Luger.380 Auto, 5.7x28mm, and.300 Blackout in subsonic loads. It is not intended for supersonic.300 BLK and is not a.45 ACP-bore can.
The 9K is rated for full-auto fire on.300 Blackout subsonic and semi-auto fire on 9mm. Check current manufacturer guidance for your specific host and rate-of-fire before building around it.
Do I still need a tax stamp for a suppressor in 2026?
No. The $200 NFA transfer tax was eliminated on January 1, 2026 by the One Big Beautiful Bill Act. The ATF Form 4 process, background check, and fingerprint requirement still apply — only the $200 tax was removed.
How long does it take to buy a suppressor in 2026?
Wait times now run in weeks rather than months for most applicants because the paperwork simplified alongside the $0 tax-stamp change. Exact timing varies with the ATF backlog and your specific Form 4 pathway.
