Magazine Catch SAVIOR For MK23 Socom pistol types

We used tape, elastic, velcro, rubber bands, anything to stop us accidentally dropping magazines. The days of adding these crude but effective modifications are over. The Hadron Airsoft Designs “Saviour” system replaces the standard single lever action catch, with two slimline independently acting, sprung catches. This means, in order to eject a magazine, both levers need to be activated, simultaneously. We also changed the direction of the activation, so the catches are are also pulled into the grip, rather than pushed down. This addition of the Saviour system to your Mk23, greatly reduces, if not eliminates, the dreaded Mk23 magazine loss in game.
