Integral Dual-Bore Suppression
Patent Pending suppressor and barrel interface enable shared volume between the two bores. Maintaining alignment, sealing, and fantastic sound reduction typically seen in a much larger pistol/silencer combination, but in a much smaller footprint.

Wipe-Based Suppressor Core
Utilizes a series of replaceable wipes & ablative media for ultra-efficient sound reduction in a compact volume.
With 2 distinct bullet paths which alternate, typical wipe life is extended to roughly double that of traditional wiped suppressor designs.

Derringer platform
The base firearm is produced in cooperation Bond Arms Inc, America’s long-time manufacturer of high quality derringers. With a locked breech design, you have two alternating shots with action noise eliminated, while the brass is retained rather than ejected onto the ground. This also means no traditional pistons or other moving parts needed for proper function. Completely foolproof mechanics.

User-Serviceable
Wipes are user-replaceable. Designed for easy maintenance with simple tools — keep quiet performance sharp with minimal effort. 3E will also offer a mail-in maintenance service.

How do I place a preorder?
We dont have a structured preorder system in place at this time. For now, sign up for our mailing list and follow us on social media to stay updated. (Links at bottom of page).

When will other calibers be available?
Most likely a few months following the release of the 9mm version, which is the priority.

We set out to build something no one had done before — and it turned into one of the quietest, coolest suppressed handguns on the market.
