Based on the commercially available SIG P320, the new Modular Handgun System can be configured as the full-size M17 or in the compact M18 configuration. MHS more than lives up to Modular aspect of its name, with possible upgrades not even yet conceived by the Army. For example, the slide is equipped with a removable plate to accept a red dot optic. Additionally, the fire control unit is compatible with other P320 grip modules.
In an initiative akin to the Special Operations Peculiar Modification (SOPMOD) program for the M4 carbine, SIG is demonstrating enhancements for MHS.
This has an M18 with an X-series grip. It incorporates an after market magwell, which works as a chute to speed reloads and also includes a Romeo 1T sight from SIG Optics as well as suppressor height front sight.
However, the slide can also be configured with an adjustable rear via the sight plate.
Additionally, they have installed a flat trigger and removed the manual safety found on MHS.
These enhancements aren’t being offered as a package, but rather as a demonstration narrator to get users to consider ways to leverage the weapon’s modularity.
SIG and after market accessory manufacturers continue to roll out new products. Even more will come now that the P320 has been adopted for US military service as MHS.
