The Pro Model configuration deletes the manual thumb safety and uses Ruger’s Secure Action internal-hammer system with a trigger blade safety. A frame-molded warning notes "PISTOL WILL FIRE WITH MAGAZINE REMOVED." Capacity is 20+1 with the included magazines.
The slide is optics-ready with an interface under a removable cover plate, and it is drilled and tapped with lightening cuts. Construction features a through-hardened alloy-steel slide in a black-oxide finish and a black-nitride-treated alloy-steel barrel. The glass-filled nylon frame keeps weight to approximately 24.5 oz unloaded.
Sighting equipment includes a green fiber-optic front sight and a fully adjustable rear sight. A multi-slot Picatinny-style accessory rail on the dustcover supports common weapon-mounted accessories. The pistol is full-size and finished in black throughout.
Key dimensions include a 4.94-inch barrel and an overall length of 8.65 inches. The case label indicates SKU 16403 Pro; Ruger’s case labels often round barrel length to 5 inches, while the correct technical specification is 4.94 inches.
