The P1S is a hybrid of the P11's grip and a P1 slide and barrel, offering a more concealable gun with a 12-round capacity. Equipped with a firing pin block and a manual safety, it provides a great and safe carry option for those who prefer hammer-fired guns. This grip doesn't have interchangeable backstraps but features deep checkering and a very comfortable grip, making it popular with both male and female users for concealed carry. The Mk23 version comes optics-ready out of the box with four baseplates for most common red dot footprints. It features a robust Mk23 locking system, an upgraded slide design, and enhanced grip texture.
