The PX-5.7 OR stands out with its internal-hammer, single-action-only trigger system paired to a delayed-blowback operating system, delivering a crisp break and consistent cycling with 5.7x28mm. The 4.8 in cold hammer forged barrel supports accuracy and longevity, and capacity is 20+1 using the included steel magazine.
The optics-ready slide is cut for the RMSc footprint and ships with a cover plate. Per Tisas factory literature, OR models include an RMR adapter. The slide is nitrocarburized and features front and rear cocking serrations for confident manipulation.
The full-size polymer frame has aggressive texturing and an undercut trigger guard for a secure, consistent grip. A full-length Picatinny/MIL-STD-1913 accessory rail on the dustcover accepts compatible lights or accessories, and the flat-faced trigger and trigger safety are standard.
Sight configuration includes a fiber-optic (green) front and a drift-adjustable, black serrated square-notch rear. Controls are observed on the left side with a left-side magazine release. Markings include PX-5.7 on the slide, caliber on the barrel hood, and the import stamp "Tisas Knoxville, TN." The steel magazine has witness holes at 5, 10, 15, and 20.
