The P1 Mk23 retains all of the advantages of the larger K100 in a smaller package. All of the new improvements of the Mk23 model are carried over to the P1 and include the ability to mount red dots, improved grip and slide traction, and the new barrel locking system.This feature is mainly appreciated at concealed carrying for personal defence. The accuracy and shooting action remains unchanged comparing to the full-sized models despite the shortened barrel. The standard sights consist of a side-adjustable steel rear sight and plastic front sight, fibre-optic front sight fitted on customer´s demand.
