The Ruger Mark IV 22/45 Lite is a single-action semi-automatic pistol in .22 LR with a 4.4-inch barrel and a ventilated aerospace-grade aluminum receiver. The purple anodized finish is an intentional aesthetic choice — it draws attention at the range. The gun ships with two magazines.

Detailed Features 

The one-button takedown is the feature most owners mention first. Field-stripping requires no tools and takes seconds, which makes cleaning after a long range session much less of a chore compared to older Mark series designs. 
 
The cold hammer-forged barrel has durable rifling and the internal cylindrical bolt keeps the sights and barrel permanently aligned regardless of how many times the gun is disassembled. The factory-installed Picatinny rail makes optic mounting straightforward. The polymer grip frame has checkered rubber panels styled after a 1911 grip, and the ambidextrous manual safety can be converted to left-side-only if needed. 
 

Usage 

At 25 oz this is a light, low-recoil .22 that works well for range training, teaching new shooters, and casual target shooting. The optics rail adds utility for those who want a red dot. It is not a defensive pistol in any practical sense, but .22 LR is inexpensive and the Mark IV handles high round counts without issues.

Owners of the Ruger Mark IV 22/45 Lite in purple are largely happy with the gun, especially as a training tool or range pistol. The one-button takedown gets mentioned in nearly every discussion — it's a genuine improvement over the earlier Mark series and makes maintenance accessible to anyone.

Accuracy is consistently described as good out of the box, with tight groups possible even at the longer end of typical pistol distances. The low recoil of .22 LR makes it popular with newer shooters and with experienced shooters who want to work on fundamentals without the cost of centerfire ammunition.

The purple finish splits opinion. Some owners specifically chose it for the look; others feel it limits versatility or resale appeal compared to a standard finish. That said, complaints about the color are minor.

A few owners report feeding issues with certain ammunition types, particularly bulk or low-velocity rounds. Premium .22 LR runs reliably. Aftermarket accessory availability is more limited than for common carry pistols, which matters to owners who want to customize heavily.
