Though it’s a 35-year-old design, the FN 5.7x28 mm cartridge has had a surge in popularity over the past few years, with every manufacturer from Ruger to KelTec getting in on the 5.7 game with a variety of handguns and rifles. Ammunition manufacturers have stepped up as well, and the once-obscure and hard-to-find cartridge is now made in a variety of forms by numerous companies. New for 2024, Turkish manufacturer Tisas is joining the 5.7 market with its PX-5.7 handgun.

The Tisas PX-5.7 is aesthetically based on the company’s PX-9 line-up of polymer-framed 9 mm handguns. The design of the frame is similar to the PX-9 but does not have interchangeable backstraps. A Picatinny accessory rail is molded into the dustcover. And that’s where the similarities end.

Unlike Tisas’ 9 mm handguns, the PX-5.7 uses a lever-delayed blowback action. The pistol’s action is fired by an internal hammer and uses Tisas’ “Tactical Trigger” with an integral trigger safety that comes from the factory with a pull weight of approximately 4 lbs. There is no manual safety provided. Safe handling of the pistol is also augmented with the extractor functioning as a loaded chamber indicator and an indicator at the rear of the slide that shows when the hammer is cocked.

The pistol’s design is ambidextrous with bilateral slide release levers and a reversible magazine release. It feeds from a proprietary steel magazine with a capacity of 20 rounds. Two magazines are supplied with each pistol. Iron sights are a front post with a fiber-optic insert and a drift-adjustable notched rear. The PX-5.7 is also available from the factory “optics ready” (OR), with its slide cut for direct mounting of optics with a Shield RMSc footprint and an adapter plate for mounting a RMR footprint optic included.

The Tisas PX-5.7 has an overall length of 8.65” with a 4.80” cold-hammer-forged barrel. Its height is 5.55”, and it weighs 25 ozs. unloaded. With fiber-optic sights only (FO), it has an MSRP of $460, and the optics-ready version has an MSRP of $500. For more information, visit
