- Fiber Optic Front Sight – Provides a bright, high-contrast aiming point for quick target acquisition in varied lighting conditions.

This pistol is built for shooters who want a flat-shooting 9mm for competition, home defense, or duty carry.

It also appeals to suppressor owners who need a factory-threaded barrel without aftermarket work.

Comparison: Strike One Mark II vs. Zev OZ9 vs. Agency Arms AOS
| Feature | APF Strike One Mark II | Zev OZ9 | Agency Arms AOS |
|---|---|---|---|
| Frame | Polymer | Polymer with steel chassis | Aluminum grip module |
| Barrel | Threaded, factory | Threaded, match-grade | Threaded, match-grade |

The Strike One Mark II offers a unique operating system at a lower price point than the Zev OZ9 or Agency AOS. However, aftermarket parts and holsters are harder to find for the Strike One. According to American Precision Firearms specs, the pistol’s barrel axis is 12mm lower than a typical Glock 17, which measurably reduces muzzle rise.

Frequently Asked Questions
Does the APF Strike One Mark II come with a threaded barrel?
Yes, the factory barrel is threaded (1/2×28) and ready for suppressors or compensators right out of the box.
What magazines are compatible with this pistol?
The Strike One Mark II uses proprietary 17-round steel magazines. Two are included. Aftermarket options are limited, so we recommend buying spares from American Precision Firearms.
Is the flat trigger adjustable?
The trigger is a fixed flat design per the Strike One lineage. It is not user-adjustable for overtravel or pre-travel, but the break is consistent at around 5.5 lbs.
Can I use standard Glock holsters?
No, the Strike One’s frame and slide profile are different from Glock. Look for holsters specifically molded for the Strike One or universal fit options.
How does the Speedlock system affect reliability?
The rotating barrel design locks up tight during firing but has proven reliable in duty use. It does require proper lubrication on the cam surfaces for consistent cycling.
