Its serialized stainless-steel fire control unit sits inside a glass-reinforced polymer grip module, supporting the P365 family’s modular architecture. The magazine release is reversible.
The slide is finished in black with front and rear cocking serrations and no optic cut. SIG-marked tritium night sights are dovetailed front and rear, with a green-outline front dot for fast sight acquisition in varied lighting.
