For sights P-10's feature fixed luminescent front and rear. - The Optics-Ready version of the P-10 ships with a blank filler plate. Additional plates for both the Trijicon RMR and Leupold DeltaPoint Pro are currently developed with other styles possible down the road. Also available are matching sights that allow the user to co-witness their optic dot with the irons. - One change is the switch to a swappable magazine release. With a change in geometry the goal was to eliminate the stiffness some customers experienced as the magazine release broke in even though it became smooth after some use. This new reversible release requires a few minutes to swap allowing the P-10 to remain lefty-friendly. - Chambering: 9mm Luger - Magazine Capacity: 10+1 - Frame: Fiber-reinforced polymer - Trigger Mech: Striker - Sights: Fixed - Barrel: Cold Hammer Forged - Barrel Length: 4.5 - Width: 1.26 - Weight: 28.2oz - Overall Length: 8 - Safety: Firing Pin Block Safety Trigger Safety
