Desert Design & Development D3-9SD SMG (9mm) - Full Auto - Law Enforcement Only

Call for Price

The D3-9SD, also known as the, “Ultimate Urban Carbine”, maintains the familiarity of the AR platform, the stealth of the H&K MP5-SD style suppressor, and utilizes the popular Glock 17/18/19 double stack 9MM pistol magazines.


The Glock Pistol is so popular with civilians, Law Enforcement, and government agencies. This carbine is designed to complement their existing Glock handguns and give them the tactical advantage of carrying only one caliber magazine and share it on both pistol and carbine. This allows quick transition from a sidearm to an extremely quiet and accurate suppressed carbine.
