- Drilled and Tapped Receiver – WHY IT MATTERS: Mounting a red dot or other optic is quick and secure, allowing you to upgrade your sighting system without a gunsmith visit.
- Two 10-Round Magazines Included – WHY IT MATTERS: Having a spare magazine means less time reloading and more time practicing shooting fundamentals with your family.
- Polymer Grip Frame with Checkered Panels – WHY IT MATTERS: The textured panels give you a secure hold even in damp conditions, helping you maintain control during rapid fire.

FAQ
What type of ammunition works best in this pistol?
Standard-velocity .22 LR ammunition with round-nose bullets, such as CCI Standard Velocity or Mini-Mag, typically feeds most reliably. Avoid subsonic or hollow-point loads for best performance.
Can I mount a red dot sight without an adapter?
Yes. The receiver is drilled and tapped to accept Weaver- or Picatinny-style mounts directly. You will need a compatible base plate or ring set for your chosen optic.
Is this pistol suitable for left-handed shooters?
The ambidextrous safety lever and magazine release are positioned for right-handed use, but left-handed shooters can operate them with practice. The grip frame is symmetrical and comfortable for both hands.
How do I clean the pistol after a range session?
Press the one-button takedown to separate the upper receiver from the grip frame. Use a bore brush and patches to clean the barrel, then wipe down the bolt face and receiver. Reassemble by aligning the rails and pressing the button back into place.
Does this model come with a lock or case?
Yes, it ships in a Ruger hard plastic case with a cable lock, two 10-round magazines, and an owner’s manual.
