Beretta PX4 Mag Pad Extended Spring E00345

The Beretta PX4 Mag Pad Extended Spring is an authentic factory original equipment manufacturer (OEM) replacement component designed to maintain peak reliability in altered magazines. This specialized extra-power spring is specifically engineered with an elongated coil stack to compensate for the added internal volume of extended magazine base pads. Wound from high-tensile strength steel wire, the component undergoes advanced heat treatments to prevent long-term memory formatting and structural fatigue under full compression. It provides the critical upward force necessary to lift heavy, full columns of ammunition consistently without experiencing binding or dragging along the inner magazine walls. Utilizing this factory-spec component ensures your handgun maintains its strict tactical cycle rate when configuration changes alter factory magazine depth.
