The OSIRIS is built upon the famous M9 platform but with a few key design changes. Inspired by a real-steel concept of this trusty sidearm, the OSIRIS is a full-auto replica with a reinforced slide and fitted with a picatinny accessory rail.
The most notable of these changes is the reinforced, solid slide which toughens the OSIRIS for those “high-stress” moments when unloading a full magazine on automatic fire downrange. Gone is the 180° ejection port and open-slide design, replaced by a thick, solid slide featuring strengthening lugs halfway down above the disassembly pin – giving the OSIRIS a unique look in the Airsoft world.
