Description Technical Specs Extended Information
 

The Ruger Mark IV 22/45 250th Anniversary model 40194 is a limited edition 22 LR rimfire pistol built for shooters who want more than a safe queen. It combines Ruger's simple Mark IV takedown system, a 1911-style 22/45 grip frame, a suppressor-ready threaded bull barrel, and a factory optic mounting solution in one commemorative package.

The barrel is marked with special "Made in the 250th Year of American Liberty" engraving, giving this Mark IV 22/45 collector appeal while keeping the pistol fully practical for range use, rimfire training, suppressor shooting, and red dot equipped target work. The 4.40" threaded bull barrel uses a 1/2"-28 thread pattern and includes a thread protector for use with compatible muzzle accessories.

Unlike earlier Ruger rimfire pistols that could be frustrating to disassemble, the Mark IV uses a one-button takedown system. Pressing the rear frame button allows the barrel-receiver assembly to tilt up and off the grip frame without tools, making field stripping and proper chamber-to-muzzle cleaning far easier.

The factory-installed scope mount supports direct mounting of RMR, DPP, and RMSc pattern optics, giving this pistol modern red dot capability right out of the box. The blued alloy steel receiver, cold hammer-forged barrel, internal cylindrical bolt design, fixed front sight, adjustable rear sight, and 22/45 polymer grip frame make this a well-rounded Ruger rimfire pistol for collectors and shooters alike.
