⚠ SUPPRESSOR — NO FORM 4 REQUIRED Since October 9, 2026, ATF no longer requires a Form 4, tax stamp, fingerprints, photos or registration for suppressors.

Outside Texas, we ship to an SOT dealer in your state. What changed · How buying one works now
The Daniel Defense NULL9TI is DD’s titanium 9mm suppressor — the pistol-caliber member of the SoundGuard suppressor family, designed to pair with threaded 9mm Daniel Defense pistols and any other 9mm platform with 1/2×28 threading. The NULL9TI extends DD’s suppressor engineering philosophy into the pistol caliber segment: titanium construction minimizes the added weight at the muzzle of a 9mm handgun, where weight concentration is more perceptible than on a rifle platform. With 147gr subsonic 9mm, the NULL9TI approaches hearing-safe levels on full-size hosts — making it a practical everyday suppressor for 9mm pistols and 9mm PCCs alike.
“NULL” is Daniel Defense’s naming convention for their 9mm suppressor line — the goal is to null out as much of the report as the physics allow. Titanium construction, combined with DD’s precision machining tolerances, delivers sound reduction performance at a weight that doesn’t transform a compact 9mm into a muzzle-heavy awkward platform.

FAQ — DD NULL9TI
What DD pistols is the NULL9TI compatible with?
Any Daniel Defense 9mm pistol or firearm with 1/2×28 threaded barrel. Also compatible with any 9mm handgun from other manufacturers with 1/2×28 threading: Glock threaded models, HK VP9, Sig P320, Walther PDP, and 9mm PCCs.
Is the NULL9TI hearing-safe with standard 9mm?
With 147gr subsonic 9mm on a full-size host (4–5″ barrel), the NULL9TI approaches hearing-safe levels (below 140 dB). Standard 115gr 9mm is supersonic and produces a supersonic crack that suppressors cannot eliminate — subsonic loads are required for maximum quiet.
Buying a suppressor now: a Form 4473 and a background check. No Form 4.
Since October 9, 2026, ATF no longer requires a Form 4, tax stamp, fingerprints, photos or registration to buy a suppressor. It transfers like any other firearm: you fill out a Form 4473, pass a NICS background check, and it is yours. No months-long wait.
Texas buyers: suppressors are legal under Texas law. Western Sport has been an SOT / Class III dealer since 2007.
Outside Texas: we ship to an SOT dealer in your state, who completes the 4473 with you. Your state’s law still decides — some states ban suppressors, and some only allow ones registered with ATF.
Want it registered anyway? ATF still accepts a voluntary Form 4. Ask us.
