Key Features
- Factory RMSc Optics Cut – Why it matters: No adapter plates needed; mount your favorite micro red dot directly and maintain a low bore axis for faster target reacquisition.
- 4.8″ Barrel with 11° Target Crown – Why it matters: The extended barrel length and precision crown improve muzzle velocity and accuracy, giving you tighter groups at distance with 5.7x28mm rounds.
- Ambidextrous Controls – Why it matters: Slide stop and magazine release are mirrored for left- and right-handed shooters, making the PX-5.7 OR Raptor equally functional for every grip style.
- Two 20-Round Magazines – Why it matters: Double-stack capacity means more rounds downrange between reloads, ideal for competition, training, or defensive use.
- Lightweight Polymer Frame – Why it matters: Reduces overall carry weight to 23.5 oz unloaded, so you can shoot longer without fatigue and carry comfortably all day.
Who It’s For
The Tisas PX-5.7 OR Raptor is built for shooters who want the high-velocity, low-recoil performance of 5.7x28mm in a modern, optics-ready platform. It suits competition shooters needing flat-shooting accuracy, home defenders wanting low felt recoil and high magazine capacity, and left-handed shooters who demand ambidextrous controls.
Pros/Cons
- Pros: Factory optics cut saves aftermarket machining; 20-round capacity is competitive; ambi controls for all users; target crown aids accuracy; price point undercuts many 5.7 pistols.
- Cons: Trigger pull is serviceable but not match-grade; aftermarket support for 5.7x28mm holsters and parts is still growing compared to 9mm platforms.

According to Tisas specs, the PX-5.7 OR Raptor weighs 23.5 oz unloaded—lighter than both the Ruger-57 and PSA Rock—while matching their capacity and offering a factory optics cut at a lower price point. One honest drawback: the trigger has a bit of take-up before the break, which some precision shooters may want to upgrade.
FAQ
Does the Tisas PX-5.7 OR Raptor come with a threaded barrel?
No, the factory barrel is not threaded. It features a standard 4.8-inch barrel with an 11° target crown. If you need a suppressor-ready option, you’ll need to check aftermarket barrel compatibility.
What optics fit the RMSc cut on this pistol?
Any micro red dot with the RMSc footprint will mount directly without an adapter. Common examples include the Holosun 407K/507K, Swampfox Sentinel, and Sig Romeo Zero.
Is the Tisas PX-5.7 OR Raptor California-compliant?
This model is not listed on the California Roster of Handguns Certified for Sale. Check your local laws before ordering; we ship to all 50 states but you must comply with state regulations.
What holsters fit the PX-5.7 OR Raptor?
Because the PX-5.7 OR Raptor has a unique slide profile, most universal 5.7 holsters may not fit perfectly. We recommend holsters custom-molded for the Tisas PX-5.7 or those designed for the Ruger-57 with a light/laser—test fit before carrying.
