Overview

Built for shooters who want a compact rimfire pistol with practical handling, this model pairs a lightweight profile with a 4.4-inch threaded barrel and 10+1 capacity. The adjustable rear sight and fixed front sight support straightforward sighting for range work, while the polymer grip frame and checkered 1911-style grips are designed to provide a secure hold. It is a sensible option for target shooting and for setups where a threaded barrel is part of the plan, though its compact format keeps the focus on controlled, deliberate shooting rather than high-volume use.

Considerations & Trade-offs

The 10+1 capacity is practical for range use, but it is still a rimfire pistol rather than a higher-capacity centerfire option.
The 4.4-inch threaded barrel is useful for suppressor or muzzle brake setup, but it adds a configuration requirement if you plan to use those accessories.
The adjustable rear sight and fixed front sight support zeroing, though the sight setup is more specialized than a simple fixed-sight arrangement.
Its compact, lightweight build is convenient to carry and handle, but that same size may feel less substantial than full-size target pistols.
