Building on a spate of recent new firearm releases chambered for the once-exotic FN 5.7 round, the aisles at SHOT Show this month seemed to reinforce that the caliber is here to stay.
While the 5.7×28 was originally just designed for FN’s PDW program– which led to the P90/PS90 and the Five-seveN series pistol– the now-NATO standardized cartridge caught a boost from Ruger in late 2019 with the Ruger 57 pistol followed soon after at SHOT Show 2020 by the prototype Diamondback DBX large-format pistol. Since then, KelTec has brought its P50 pistol to market, the CMMG Mk57 has appeared, and the DBX has started to appear on dealer’s shelves. In the meantime, FN updated the Five-seveN with new features and colors.
With Vista’s ammo brands (Federal, Speer, etc.) pumping out new 5.7 rounds as fast as they can to keep up with the trend, even more 5.7-chambered guns are inbound.
