Key Features
- Four removable hand grips — Why it matters: The included backstraps let you customize the grip for different hand sizes, making this pistol perfect for multi-user training or growing shooters.
- SA/DA trigger with thumb safety — Why it matters: The single-action/double-action system gives you a lighter first shot or a heavier pull for carry, plus a manual safety adds an extra layer of security for new shooters.
- MIL-STD 1913 Picatinny rail — Why it matters: You can easily mount a weapon light or laser for low-light practice, extending your training options without needing a gunsmith.
- 15-round magazine capacity (3 magazines included) — Why it matters: Three magazines mean less time reloading at the range and more time building muscle memory, especially for family practice sessions.
- 3-dot sights — Why it matters: These standard sights give you a clear, fast sight picture for accurate shooting right from the start, no upgrades needed.
Who It’s For
This pistol is built for families, youth shooters, and beginners who want a reliable, full-size 9mm for range training, home defense, or learning the fundamentals. The adjustable grip and SA/DA trigger make it a great choice for instructors teaching multiple students, and the 15-round capacity keeps the focus on shooting, not reloading.
Pros & Cons
- Pros: Ergonomic grip options, smooth SA/DA trigger, durable polymer frame, three magazines included, affordable price.
- Cons: The trigger pull in double-action mode is a bit heavier than some shooters prefer for rapid fire — an honest trade-off for the added safety.

FAQ
Is this pistol good for a beginner shooter?
Yes. The SA/DA trigger lets you start with a heavier double-action pull for safety, then switch to single-action for precision. The adjustable grip helps smaller hands get a proper hold, and the 3-dot sights make aiming straightforward.
Does it come with a holster?
No, the K-100 MK23 ships with three magazines, a cable lock, and a hard case. You’ll need to purchase a holster separately. I recommend a paddle holster for range use or a quality Kydex option for carry.
Can I mount a red dot sight on this pistol?
Not directly — the slide is not cut for a red dot. However, you can use a dovetail mount adapter or have the slide milled by a gunsmith. The Picatinny rail allows for a laser/light combo instead.
Is this pistol legal in my state?
Most states allow this model, but some restrict magazine capacity over 10 rounds. Check your local laws before ordering. We ship to all 50 states where legal.
