We first ran across GOSAFE’s lockable magazines at SHOT earlier this year. GOSAFE makes two products, a magazine and a “mobile safe.” The GOSAFE Mobile Mag is a 10-round lockable magazine for GLOCK 17, 19 and 34 pistols (more models to come in the future). The Mobile Safe looks like the Mobile Mag, but is a solid piece of plastic for the same guns that doesn’t load rounds, but locks and prevents a pistol from being used.
