APF Strike One Mark II 9mm Stainless Pistol 5.4″ Threaded Barrel 17rd

Description

The Strike One has an interesting backstory. It was originally developed in Italy by Arsenal Firearms as a candidate for Russian military and law enforcement adoption, and the design philosophy behind it was simple: build the flattest-shooting, fastest-cycling service pistol possible. The result was a striker-fired, polymer-frame 9mm that ditches the tilting Browning barrel entirely in favor of a straight-running, in-line action. That one engineering decision is what makes the whole platform different from just about everything else on a gun shop wall.

What Sets the Strike One Mark II Apart

Most locked-breech pistols rely on the barrel tilting upward to unlock from the slide during recoil. The Strike One uses a Y-shaped Speedlock locking block instead, which drops straight down to disengage the barrel. Because the barrel never tilts, the slide can sit dramatically lower over the grip, putting the bore axis at roughly 12mm from the top of the grip. For reference, a Glock 17 sits at around 20mm. That's not a marketing stat, it's a mechanical reality you feel from the first shot. Muzzle flip is noticeably reduced, the recoil impulse feels more linear, and getting back on target happens faster. The barrel also stays in a consistent straight-line path, which contributes to solid mechanical accuracy.

The Mark II version brought refinements over the original Strike One, including the flat-faced trigger that sits at a pull weight of around 5.29 lbs. The trigger uses an innovative horizontally-operating sear mechanism rather than the conventional vertical arrangement, which plays into that short, crisp release. This stainless silver model adds an eye-catching finish that also shows off the quality of the machining on the slide.

Strike One Mark II at the Range and Beyond

The 5.4" threaded barrel (1/2×28 RH) opens the door to suppressor use or a compensator, and the included fiber optic front sight gives you a fast, bright acquisition point for both strings of fire and low-light situations. At this barrel length, you also get a bit more sight radius than a typical compact or service pistol, which helps with precision at distance. Reviews and range reports consistently note that the platform handles standard 9mm loads and +P ammunition reliably, which is good to know for anyone using it outside of punching paper.

This is a full-size pistol, so it fits best in an open-carry or range context, though it's flat enough that some folks do run it under a cover garment with the right holster. It ships with two 17-round magazines, and the flared magazine well makes reloads clean and predictable. If you've been looking for something genuinely different from the sea of Glock-pattern pistols and want a platform with legitimate engineering credibility behind its feature set, the Strike One Mark II delivers that in a package that's hard to dismiss.
