Overview

The Ruger-5.7 was introduced in December 2019 to be a more affordable alternative 5.7x28mm semi-automatic pistol compared to the FN Five-seven pistol (which had been the only other 5.7x28 pistol available to the civilian market for over 20 years).^[5] Since 2020, several different pistol designs from several different firearms manufacturers came into the market that expanded the 5.7x28mm’s growing popularity,^{[citation needed][peacock prose]} including the PSA 5.7 Rock in January 2022, the S&W M&P 5.7 in January 2023, the TİSAŞ PX-5.7 in January 2024 and the Kel-Tec PR57 in January 2025.
