FAQs
1. Do I need a special mount for the KP-9?
Not always. Most optics like the Holosun HS510C and Trijicon MRO mount directly to the KP-9 Picatinny top rail. Some premium models like the Aimpoint T-2 may require a low-profile adapter.
2. What MOA dot size works best for KP-9?
For CQB and home defense, a 2 MOA dot offers the perfect balance of precision and speed.
3. Is a holographic sight better than a standard red dot?
For very close ranges and fast transitions, holographic optics like the EOTech EXPS3 can give you an edge. But they’re heavier and drain batteries quicker.
4. Will the recoil of the KP-9 affect zero retention?
No. The KP-9’s 9mm blowback system produces mild recoil, and all optics in this list held zero after 500+ rounds.
5. Which is the absolute best overall red dot?
For most shooters, the Holosun HS510C offers the best mix of price, performance, and ruggedness.
