Key Features
- Compensated 4.2-inch Barrel — WHY IT MATTERS: The factory-installed compensator reduces muzzle rise by redirecting gas upward, so you stay on target for faster follow-up shots. This is a huge advantage for newer shooters learning recoil control.
- Low-Profile Optics Mounting System — WHY IT MATTERS: You can mount popular red dots like the Trijicon RMR or Holosun 507C directly using the included plates. No gunsmithing needed, and the low height keeps the optic close to the bore axis for natural point of aim.
- Lightening-Cut Slide — WHY IT MATTERS: Reduces reciprocating mass, which means less felt recoil and quicker slide cycle. This helps you shoot faster without fighting the gun.
- Flat-Faced Trigger — WHY IT MATTERS: The trigger has a clean break and short reset, making it easier to shoot accurately. The flat face gives you consistent finger placement shot after shot.
- Co-Witness Height Fiber-Optic Front Sight — WHY IT MATTERS: The front sight is tall enough to see over a mounted red dot, so you can still aim if the battery dies. The fiber optic picks up ambient light for a bright aiming point in any lighting.
Who It’s For
This pistol is for the shooter who carries daily but wants the performance of a full-size competition gun. It’s also a great choice for a family member who is moving from a larger home-defense pistol to something more concealable but still easy to shoot. Youth shooters who are ready for 9mm will appreciate the reduced recoil from the compensator and slide cuts. Beginners will find the flat trigger and optic-ready design forgiving as they learn fundamentals.
Pros & Cons
- Pro: Factory compensator means no extra cost or fitting — it works right out of the box.
- Pro: Three magazines included give you 36+ rounds total, great for range days or classes.
- Pro: Optics mounting system is simple and works with most popular red dots.
- Con: The compensator adds length to the barrel, so holster compatibility is limited to models designed for the 4.2-inch barrel with a comp. You may need to check holster fit before buying.
