With more than a dozen models available -- and with different models sharing grip modules, slides, barrels, and calibers -- figuring out the P365's dimensions, and which model you may want to configure or buy can get confusing. We've collected the dimensions for all models to make it easy!
P365 Models & Dimensions
Models are generally listed in descending order, from smallest to largest. Note that individual components -- like the slide, barrel, and frame (grip module) -- can be individually swapped on any P365 model, thereby reconfiguring its dimensions and caliber.
