Ruger Mark IV

One-Button Takedown: Why It Matters

Earlier Ruger Mark pistols were notorious for difficult reassembly — a genuine frustration for a .22 that gets cleaned frequently after hundreds of rounds of rimfire residue. The Mark IV eliminates this entirely with a single button at the rear of the frame that releases the upper assembly. Open, clean, reassemble in seconds. For anyone who shoots rimfire regularly and knows how dirty .22 LR ammunition is, this alone makes the Mark IV meaningfully more practical than its predecessors. If you've avoided Mark II or III pistols due to the disassembly reputation, the Mark IV resolves that completely.

Standard vs. Target: Choosing Your Configuration

The Standard configuration offers a tapered barrel in 4.75 or 6-inch length with fixed sights — a straightforward, affordable .22 pistol that handles well and shoots accurately for plinking and small game. The Target configuration steps up to a heavier bull barrel, fully adjustable target sights, a wider trigger, and the option for a Viper red dot package. The Target models are the choice for rimfire competition, precision small game hunting, and shooters who want the most accurate possible platform out of the box. The Tactical variant adds a threaded barrel for suppressor use and a Picatinny rail for optics — the most popular choice for suppressed .22 shooting. For general plinking and training: Standard. For competition and precision: Target. For suppressed shooting: Tactical.

Mark IV for Handgun Training and Skill Building

The Mark IV is one of the most effective training tools available for handgun shooters. Its ergonomics closely mirror a full-size service pistol, the trigger action rewards good technique, and .22 LR ammunition costs a fraction of centerfire calibers — enabling far more repetitions per dollar. Shooters who work on trigger control, grip, and sight alignment with a Mark IV translate those skills directly to their centerfire carry guns. Many competitive shooters and instructors recommend a Mark IV or similar .22 pistol as a training supplement to reduce centerfire training costs without sacrificing trigger time. It's also an excellent first handgun for new shooters who want to develop fundamentals before stepping up to centerfire.

Rimfire Competition: Mark IV in Silhouette and Precision Events

The Mark IV Target competes in NRA Precision Pistol (Bullseye), rimfire silhouette, and Steel Challenge competition. The bull barrel Target models consistently produce sub-1-inch groups at 25 yards with quality ammunition, making trigger technique and ammunition selection the limiting factors rather than the pistol. The Mark IV has a deep history in these disciplines going back to its Mark I origins, and the current generation continues that competitive tradition. For Steel Challenge, the Mark IV Lite (aluminum frame) offers a lighter option that some competitors prefer. For serious rimfire competition at any level, the Mark IV Target is a proven choice.

Optics and Accessories

Most Mark IV models accept optic mounts via the Weaver-style rail on the receiver or aftermarket scope bases. Target and Competition models come drilled and tapped for direct scope mounting. The Holosun and Vortex Viper red dot packages are popular for competition use where a dot speeds target acquisition. The aftermarket ecosystem is extensive — triggers, grips, extended magazines, and suppressor-height sights are all widely available. The 10-round magazines are standard; aftermarket options exist. The Mark IV accepts all standard Ruger Mark series magazine variants.

Mark IV vs. Browning Buck Mark: The Classic Comparison

The two most compared .22 target pistols are the Ruger Mark IV and the Browning Buck Mark. Both are excellent; the choice often comes down to grip preference and ergonomics. The Mark IV has a straight, narrow grip that some shooters find better suited to a target grip style. The Buck Mark has a more ergonomic grip that some shooters find more comfortable for extended shooting sessions. Both offer similar accuracy, similar aftermarket support, and similar price points at comparable trim levels. The Mark IV's one-button takedown is a genuine advantage in practice. The Buck Mark's trigger is often cited as slightly better stock for stock. Handle both if possible before deciding.
