Stealth Additive Works SHIV 9mm Titanium Suppressor

The Stealth Additive Works SHIV is one of the lightest 9mm suppressors on the market — 2.5 ounces and 3.7 inches of 3D-printed Grade 5 (ELI) titanium. That low mass is the whole point: on most 9mm pistols the SHIV runs reliably with no booster at all, eliminating the complexity, wear, and added length of a Nielsen device.

Reliable semi-auto cycling depends not just on how much a can weighs but on where that weight sits, and the SHIV's center of mass is tuned to keep pistols running while still delivering meaningful sound reduction. It's an easy fit on a home-defense PCC or a carry-size pistol, where cutting muzzle blast indoors can make the difference between a bad day and permanent hearing damage.

Host Compatibility Notes

• The Glock 17, 19, and 34 are among the most cycling-sensitive hosts for suppressor use, even with a booster. A reduced main spring weight may be needed depending on ammunition and shooter recoil management.
• Some setups see a 30–50 round break-in period before cycling settles in.
• Direct thread only — no 3-lug, tri-lug, or HUB adapter compatibility.
