Chambered in 5.7x28mm, this Ruger-57 offers a 20+1 capacity and a manual-safety configuration with no magazine disconnect, allowing the pistol to fire with the magazine removed. Safety features include an ambidextrous manual safety, bladed trigger safety, hammer catch, and an inspection port for quick visual status checks.
The 4.94 in alloy-steel barrel is black-nitrided and non-threaded with a 1:9 in RH twist. Its delayed-blowback operation pairs with Ruger’s Secure Action and protected internal hammer for a smooth, consistent trigger system that does not require the trigger to be pulled for disassembly.
The slide is finished in black oxide and cut with front and rear serrations plus a top lightening window. Tool-free takedown simplifies maintenance. An accessory rail is integrated for mounting compatible lights or other rail-based equipment.
Sight readiness is straightforward and fast: the pistol wears iron sights with a green fiber-optic front and a serrated rear that is adjustable for windage and elevation. The glass-filled nylon polymer frame is finished in black with textured grips bearing Ruger phoenix logos. The factory case label lists “RUGER-5.7,” barrel “5 in,” and SKU 16414, and the 643- serial prefix falls outside Ruger’s manual-safety retrofit bulletin range.
