This UDP-9 Pistol comes with the Maxim Defense stabilizing brace and a quick attach 3-lug mount SilencerCo Octane 9 2.0 suppressor.  It is a compact AR-15 style firearm chambered in 9mm and fed with GLOCK® magazines.  It features last round bolt hold open.  We have removed the original Angstadt handguard and replaced it with an Odin Works 9.5″ M-LOK style handguard to aid in shielding the suppressor.  The quick attach 3-lug feature allows for a painless removal of the suppressor to allow for cleaning and maintenance.

This item also comes with the original Angstadt handguard to accomodate you firing the pistol while waiting on the ATF suppressor approval.

SilencerCo Octane 9 2.0

The Octane has a rich history, from the original in the days of SWR to the extremely popular Octane HD from SilencerCo. The Octane 2.0 is SilencerCo’s lastest revision, and revival, of the series. The Octane 2.0 is user serviceable, allowing shooters to utilize cast lead projectiles as well as use the suppressor the the extremely dirty 22LR cartridge. The mix of aluminum and steel construction allows the SilencerCo Octane 2.0 to be durable enough for full auto use, but still weigh in at under 10 ounces.
