It is chambered for the FN 5.7×28mm cartridge and is characterized by its generally low recoil.

The frame is made out of polymer,^[4] the slide and barrel are made out of 416 stainless steel^[5] and the magazine is made out of black oxide alloy steel.^[6]

PSA offers the barrel finished in several colors, it can be bought threaded and non-threaded.^[7]

The standard magazine holds 23 rounds, 3 more than the FN Five-seven. It is also a competitor to the Ruger-57, the M&P 5.7 and the TİSAŞ PX-5.7.^[8][9]
