Angstadt Arms MDP-9

Angstadt Arms has released the details for the new MDP-9 and it probably isn’t what you thought it would be… unless you called a roller-delayed blowback PCC that takes Glock mags.


Here are the bullet points from Angstadt Arms:

It’s a true roller-delayed blowback design! It has very low recoil, is great for suppression and all around more pleasant shooting experience that other 9mm actions.

Yes…it runs on Glock magazines, has last round bolt hold open and an extended mag release.

It’s ultra-compact and lightweight, just 14” long and 3.6lbs (empty)

Charging the MDP-9 is done via a non-reciprocating forward charging handle that can be swapped from left to right side.

The barrel is from an MP5 K (5.85″) and has a 3-lug. All other parts in the upper assembly are proprietary to the MDP-9 (including trunnion, bolt, rails, etc.).  

It’s backwards compatible. The monolithic upper assembly can be dropped on an AR-9 or AR-15 lower receiver. For customers that want to upgrade their existing guns, they can purchase the upper receiver assembly. It will include the rear picatinny rail adapter to close the gap and allow for brace mounting options.Goodbye buffer tube! The MDP-9 has a super slim 1913 end rail that can accept a wide variety of pistol brace and rifle stock options. The supplied images show the MDP-9 pistol with no brace as well as with a SB Tactical side-folding 1913 brace. You can also use the telescoping MPX PSB. The MDP-9 upper assembly has receiver cuts to accommodate the rails.

User serviceable. The bolt, rollers, locking piece and rails are made from hardened steel and can be swapped out by the end user. The upper receiver assembly is 7075-T6.
