Developed with Mischief Machine, this Commander Series variant uses a precision 7075‑T6 aluminum grip module with hard‑coat anodizing and G10 grip panels. The integrated 1913 accessory rail and micro-size profile deliver compact dimensions with true metal-frame rigidity.
The slide is marked “MASADA 9S” and features front and rear serrations and beveled edges. It is factory cut for direct mounting of Shield RMSc-footprint optics. SIG P320‑pattern sight dovetails broaden sight options, and the installed drift‑adjustable iron sights use a white‑dot front and plain black rear.
A 3.1 in stainless steel barrel, striker‑fired action, and a flat‑faced trigger with an integral safety tab provide a modern shooting setup. The design centers on a modular fire control unit, allowing the aluminum grip module to serve as a durable foundation.
This pistol accepts both 13‑ and 17‑round factory magazines and is rated to 17+1 capacity. Proof and import markings include IWI US – Middletown, PA and IWI – Israel, with country of origin listed as Israel. The factory part number is M9SLIM13CE.
