If you carry a Glock 19 or 23 with a weapon light like an ITI M3 or TLR-1, the Safariland 6378 holster is a solid choice for everyday carry. It uses the ALS (Automatic Locking System) to securely lock your firearm in place—just holster it and you’ll hear a click. When you need to draw, a quick swipe of your thumb releases it smoothly. The holster comes with both a contoured paddle and a belt loop, so you can switch between easy on/off paddle wear or more stable belt carry. Fits belts from 1.5 to 1.75 inches wide. The STX black finish looks professional, and the suede lining inside protects your gun’s finish and sights. It’s low-profile enough for concealed carry but built tough for duty use. Whether you’re a plainclothes officer or a responsible civilian, this holster offers great retention, comfort, and versatility.
