Owners who pick up a P320 M17 Military Surplus unit are generally pleased with the condition these pistols arrive in, having been through military service but still mechanically sound. The night sights and manual safety are considered a value addition by most buyers, particularly those who prefer the added manual safety option that civilian P320 variants do not always include.

The M17 platform itself gets broad praise for its modular design, smooth trigger, and comfortable grip ergonomics. Some surplus buyers do note minor cosmetic wear consistent with issued firearms, and opinions vary on whether that adds character or detracts from appearance. Function after a basic cleaning is universally reported as reliable.

From a value standpoint, the Military Surplus designation is seen as an opportunity to get a proven, issued pistol at a price below a new equivalent. The main point of debate is the manual safety, which some P320 enthusiasts prefer to omit but others specifically seek out. Overall, the M17 surplus market has developed a loyal following among buyers who want the military-spec configuration.
