The Tyrant Designs® SA15 Magazine Base Plate for Glock® 43X/48 pistols features a CNC-machined, anodized aluminum body, while chamfered edges make for a snag-free profile, and the relief-cut sides provide a solid grip. The Tyrant Designs base plate adds just enough weight to deliver a reliable, more positive magazine release for smooth, snag-free reloading. Better yet, this magazine base plate offers quick, tool-free installation for reliable, field-ready performance.
