The Ruger Mark IV Target is a single-action .22 LR pistol that works well for both competitive target shooting and casual range use. The one-button takedown system lets you field-strip it without tools, which makes cleaning straightforward enough that it doesn't feel like a chore.

Detailed Features 

The grip frame is CNC-machined from a single piece, which keeps tolerances consistent. The cold hammer-forged barrel produces tight rifling that holds up over high round counts. Internal cylindrical bolt construction maintains sight-to-barrel alignment independent of the grip frame, a design advantage over conventional setups. 
 
The contoured grip includes replaceable panels for a non-slip hold, and the receiver is drilled and tapped for Weaver or Picatinny-style rails if you want to mount optics. An ambidextrous manual safety can be configured for left-handed use, and a magazine disconnect prevents firing when the magazine is removed. The threaded barrel accepts suppressors including the Ruger Silent-SR. 
 
Comes with two 10-round magazines and a hard plastic case. 
 

Usage 

The 5.5-inch barrel and adjustable rear sight suit target shooting at 25-50 yards where the .22 LR's inherent accuracy shows up most. The light recoil makes it a reasonable trainer for new shooters, and experienced competitors use it for rimfire events. The weight (4.3 lbs) adds stability during slow-fire strings but becomes noticeable on a long range day.

The Mark IV Target draws consistent praise for accuracy. Shooters report tight groupings at 25 and 50 yards, and most credit the cold hammer-forged barrel as the main factor. The grip fits a wide range of hand sizes comfortably, and the low recoil of .22 LR means follow-up shots require almost no correction.

The one-button takedown is the most-mentioned quality-of-life feature -- owners who previously owned Mark II or Mark III pistols particularly appreciate how much simpler cleaning has become.

On the critical side: the price sits higher than competing .22 pistols, which comes up regularly in value discussions. Some shooters find the 4.3-lb weight tiring during extended sessions and would prefer a lighter option for carry or all-day plinking. A handful of users note a break-in period before the pistol feeds reliably with certain bulk .22 LR loads. Magazine loading can be stiff early on as well.

Aesthetics are a minor point of debate -- the classic silhouette appeals to those who grew up with the Mark series, but shooters accustomed to modern striker-fired designs sometimes find the profile dated.
