Compact, low-recoil pistol-caliber carbines have become a top choice for operators and serious enthusiasts who want a lightweight, controllable rifle that’s easy to carry and quick to manipulate. The market is increasingly rewarding designs that shave weight without sacrificing reliability or magazine compatibility.

ANGSTADT ARMS MDP-9 is a standout because it pairs a novel action with practical ergonomics. The MDP-9 features a patent pending roller-delayed action which significantly reduces the weight and recoil of the gun, making it one of the softest shooting pistol caliber carbines on the market. At just 14″ long and 3.6 lbs., it’s small enough to be carried comfortably on a sling or in a backpack. It runs on Glock 9mm double stack magazines, includes last round bolt hold open and an extended mag release — all features that make magazine changes much faster than conventional subguns.

Design and mechanism

The patent pending roller-delayed action is the headline feature. By delaying bolt opening with a roller mechanism, felt recoil is reduced and the need for heavy reciprocating mass is minimized — which explains the MDP-9’s 3.6 lb carry weight. That translates to less muzzle rise, faster follow-up shots, and a more pleasant training and defensive experience with 9mm ammunition.

Magazine and controls

Compatibility with Glock 9mm double stack magazines is a tactical advantage: reliable feeding, wide magazine availability, and proven magazine ergonomics. The last round bolt hold open provides immediate visual and tactile feedback on ammunition state, while the extended mag release helps speed reloads under stress — a clear design choice for operators and competition shooters.

Price is $2044.99, positioning the MDP-9 as a premium, purpose-built option in the semi-auto pistol-caliber carbine segment. View product details and pricing

Performance and applications

Chambered for 9mm reliability and controllability, the platform excels for close-quarters defense, patrol use, and PCC competition. The light weight and compact 14″ profile make it practical for off-duty carry on a sling or stored in a pack. Angstadt Arms’ attention to control layout and magazine speed addresses common operator needs for rapid, repeatable reloads.

For buyers seeking a lightweight, low-recoil 9mm carbine with modern controls and Glock-mag compatibility, the ANGSTADT ARMS MDP-9 is worth evaluating. Check current availability on the product page where purchases are completed through the retailer. Check availability
