The P-10S is the smallest P-10, a subcompact made to be carried. A small gun is harder to shoot well, which is why sights and a red dot matter more on it than on a full size pistol: a short sight radius forgives less, and a dot removes that problem.
Small gun, red dot
An optics ready P-10S takes the same plates as the rest of the P-10 family, in RMR, RMSc, K-series, DPP, Docter and other footprints. For a carry gun, a slim optic on an RMSc or K-series plate keeps the slide narrow. Slides without a cut take a dovetail mount. See Optics ready plates for CZ P-10S and Red dot mounts for CZ P-10S.
Sights you can see at night
Self lit tritium vials suit a pistol kept for defence. Fiber and blank sets, OR heights and adjustable LPA rears fill the rest of Sights for CZ P-10S.
Springs
Eemann Tech's P-10 springs fit the S as well: a lighter trigger bar pair, firing pin springs and the small springs that wear first. They are in Springs for CZ P-10S.
Frequently asked questions
Will a large optic fit the P-10S?
It may overhang the slide. A slim optic with an RMSc or K-series footprint suits the short slide best.
Are tritium sights legal to buy?
They are sold freely in most countries, but some countries restrict tritium. Delivery is not possible to every destination.
