Ruger 22/45 Threaded Barrel


The Ruger 22/45 Threaded Barrel is a semi-automatic large-frame pistol chambered in .22 LR. The 22/45 Threaded Barrel is one of four primary pistols in Ruger’s 22/45 Series–a series that combines Ruger’s Mark III action with the famous 1911’s grip. What makes the Threaded Barrel unique to the series is, of course, its threaded barrel for easy application of a suppressor or other barrel accessories.

The 22/45 is blowback operated, meaning the initial explosion of the cartridge powers the cycling. It uses an internal cylindrical bolt for its action. How it’s different from a standard design is it recoils out of the pistol instead of pushing a slide back.

The 22/45 Threaded Barrel features alloy steel construction, and includes a 4.5″ barrel. The 22/45 Threaded Barrel includes a loaded chamber indicator that offers both visual (red mark) and tactile (protruding notch) indicators. Additional features include interchangeable polymer grip plates and a magazine disconnect feature prohibits the gun from firing when the magazine is released.

The 22/45 Threaded Barrel is available with or without sights. The model without sights has instead two Picatinny rails, one on top and one on bottom, for easy mounting of optics or accessories.

Editor Review

The Ruger name is synonymous with .22 LR pistols and the company has a vast array of offerings that are useful for plinking, target shooting and marksmanship practice. One of their better products is the 22/45 Bull Barrel Model.

Offered in stainless or blued versions, the little Ruger has a 10 round capacity, adjustable sights and a 5.50” bull barrel. It also comes from the factory with a scope rail so that a red dot or other optic can easily be mounted.

A zytel polymer frame makes the 22/45 light and easy to handle for shooters of all ages. The excellent accuracy, mild recoil and the inexpensive cost of .22 LR ammo make it a great choice for teaching beginning shooters.

The crisp single-action trigger and grip angle also make the 22/45 a perfect trainer for fans of the 1911A1 pistol, and it was originally designed for that purpose.

 All the controls are well laid out and unlike some other .22 pistols on the market, the Ruger magazines are easy to load and well built. A well thought out loaded chamber indicator makes it a breeze to identify if there is a round in the chamber. As we know, however, all guns are considered loaded until they are properly cleared. Still, the loaded chamber indicator is a nice touch, particularly with for less experienced shooters.

A standard feature on the 22/45 that might ruffle some feathers is the magazine safety which is designed to keep the gun from firing unless there is a magazine in the magwell. Many shooters think a magazine safety is a solution in search of a problem, but for a gun used to teach beginners, it is a viable option.
The only drawback is it might create a false sense of security when a beginner transitions to a gun without a magazine safety. Such a possibility can easily be mitigated by teaching proper firearm safety.

Because of the lack of recoil and superior accuracy, the 22/45 is right at home as a training aid for more experienced shooters. So, it offers something for the first time shooter and the longtime handgun aficionado.

In all honesty, the little Ruger is so much fun to shoot it is hard to find negatives. Even my 10 year-old daughter can easily handle the 22/45, and we’ve had a lot of fun plinking while I teach her proper firearms safely.  Aluminum cans, paper targets and even golf balls have all fallen to her and the Ruger 22/45.

Few guns are are versatile enough to be a viable training tool for serious shooters, and are also a great choice for a day spent plinking with the kids. 

The 22/45 offers a modest price tag, excellent ergonomics and superior accuracy, which makes it a great addition to any firearms collection.

Where it truly excels, however, is by being so much fun to shoot.
