The 5.7x28mm round sparked a revolution in personal defense when FN Herstal introduced it in 1990. Now, over three decades later, this specialized cartridge powers some of the most advanced pistols on the market, combining the flat-shooting performance of a rifle round with handgun portability. Gun enthusiasts seeking the perfect balance of speed, accuracy, and effect on target turn to 5.7x28mm pistols as their solution. We’re looking at 7 excellent pistols chambered in this unique round.
7. Kel-Tec P50
Kel-Tec took a fresh approach with the P50, using P90-style magazines to pack 5.7x28mm into a unique package. The top-loading, hinge-open design is classic Kel-Tec: keep things different, no matter what. A 9.6-inch barrel maximizes the round’s potential, while the simple blowback system keeps maintenance straightforward. At the end of the day, the P50 is still a Kel-Tec, which means some shooters love the guns and some hate them. For the money, the P50 is a fun gun less meant for practical applications and more meant as a range toy. If there’s room in the budget (and for 5.7 ammo after) it’s worth considering.
6. CMMG Banshee MK57
The CMMG Banshee MK57 brings serious performance to the table with its 8-inch barrel design. Its radial delayed blowback system handles any commercial ammunition with ease, while thoughtful controls make shooting a breeze. The balanced weight distribution helps shooters stay on target during rapid strings. Available in multiple Cerakote finishes, this pistol blends capability with personalization for shooters who demand both.
5. Smith and Wesson M&P 5.7
Smith & Wesson’s M&P 5.7 brings the famous 5.7 round to more shooters without breaking the bank. The gas system handles recoil beautifully, while the textured grip keeps the gun steady in any conditions. With 22+1 capacity and tool-free maintenance, this pistol focuses on real-world usability. Polished internals ensure smooth feeding with any factory ammunition, and at a price significantly below FN’s.
4. Diamondback DBX 57
Diamondback built the DBX 57 for shooters who need compact power. The short-stroke piston system keeps things running smoothly, while M-LOK slots let users add exactly what they need. An 8-inch barrel delivers full performance in a handy package. The aluminum construction keeps weight down without sacrificing durability, and suppressor-ready threading adds options for running a more hearing-safe setup.
3. Ruger 57
Ruger designed their 5.7 pistol around shooter comfort and control. The locked-breach design manages recoil effectively, while the bright front sight gets you on target fast. Steel construction in key areas enhances longevity, and the 20-round magazines feature thoughtful details like witness holes. Every control falls naturally underhand, making this pistol especially welcoming to new 5.7 shooters.
2. PSA Rock 57
Palmetto State Armory made the 5.7 round accessible without cutting corners. The delayed blowback action handles pressure spikes smoothly, while the grip texture ensures solid control. Steel internals promise longevity, and the optics-ready slide welcomes popular red dots. With a 23-round capacity and proven reliability, the Rock 57 delivers exceptional value.
1. FN Five-seveN
FN America’s Five-seveN launched the civilian 5.7x28mm revolution. Thanks to smart engineering, this lightweight pistol still maintains minimal recoil. Safety features include dual disconnectors and clear indicators, while practical touches like adjustable sights make it easy to aim and shoot. The clean-breaking trigger and ergonomic grip show why this design has stood the test of time.
