The plus-one capacity figure is a magazine count plus a chambered round, which is different from a listing that quotes the magazine alone. The coyote pvd finish is the surface treatment to match if you are comparing color or coating with another SIG Sauer configuration of the same model. The model name to compare is M18X CSS. A close SIG Sauer model can differ in finish, capacity, barrel, sights, or included parts, and those differences are the reason this page stays with this configuration.

The caliber to match is 9mm. The same model name in another caliber is a different firearm. Additional information on this page repeats the published specification list for this exact configuration. If a measurement is not in that list, it is not stated here and should not be assumed. Read as a checklist, manufacturer is SIG SAUER, model is M18X CSS, caliber is 9mm, action is Striker Fired, barrel length is 3.9", capacity is 21 + 1, finish is Coyote PVD, and sights is Siglite Front/Rear.
