As the old commercial observed, sometimes you feel like a nut, sometimes you don’t. Along those lines, sometimes you can get away with OWB, and sometimes you can’t. Most gun guys and gals have two different rigs for those very different circumstances.
But while one tool for two jobs sometimes means it does neither one well, there’s an advantage a “convertible” holster like Blade-Tech’s Total Eclipse. You can change on the fly. Plus, you save some dinero. We’d guess both of those were considerations for Mike A when he was deciding on a rig for his GLOCK 43.
