Best 5.7×28 mm Pistols: Features and Performance

If you’re looking for a fast-shooting handgun with low recoil and good range, you should check out the 5.7×28 mm caliber. Once in the military or special-ops-only territory, this caliber brings together velocity, low recoil, and high magazine capacity in a pistol you can shoot with more accuracy and efficiency than its size and specs would indicate.

This article breaks down the top 5.7×28 mm pistols — what really matters when at the range or on the street — including recoil management, reliability, ergonomics, sights/optic options, and real-life considerations such as the availability of ammunition.

Whether you want a range gun for fun, need an edge in competition, or want to carry it, this article will provide simple, straightforward, and experience-based analysis to help you buy the right gun.

History of 5.7X2.8 mm Pistol

You almost certainly want the 5.7×28 mm cartridge, which was developed around the late 1980s by FN Herstal in response to a requirement from NATO for a Personal Defense Weapon (PDW) that possessed effectiveness against modern body armor while retaining a light, controllable profile.

FN matched the new cartridge with two platforms, the compact P90 PDW (early 1990s) and the Five-seveN pistol (later, in the 1990s). The round, which was developed in an SS190 armor-penetrating version for military use, was based on the concept of very high velocity, very low diameter projectiles, and low recoil when compared to large handgun calibers.

As time went on, the 5.7×28 mm transitioned from a niche military alternative to a civilian market hit, valued by shooters for its flat trajectory, light recoil, and its ability to be fired from high-capacity magazines.

The availability of civilian loadings (non-armor-piercing) combined with improved pistol designs raised interest in the caliber through the early 2000s and 2010s, although uptake has been limited by the availability of ammo, costs, and sometimes significant legal/regulatory differences between countries. Today, the 5.7 is best known for its unique combination of accuracy and low recoil in small packages.

5 Top 5.7x28mm Pistols

1. FN Five-seveN

Created by FN Herstal in the 1990s to complement the 5.7×28 mm PDW cartridge, the Five-seveN provides a high-velocity, low-recoil option for military and civilian shooters. Recoil is very light; fast follow-up shots; reliable with the correct 5.7 ammo; great ergonomics for rapid-firing control.

It produces tight groups for a service pistol — practical accuracy is superb at normal defensive distances, but far more than adequate at extended distances for handguns with quality ammo and optics.

Specifications

Caliber: 5.7×28 mm

Action: Delayed blowback, single-action

Barrel length: 4.8 in

Overall length: 8.19 in

Weight (unloaded): ~21–25 oz

Magazine: 10- or 20-round

Optic-ready: Yes (MRD/Mk3)

Pros and Cons

Pros

• Minimal recoil → quicker, more accurate follow-up shots.
• Slim grip paired with larger capacity magazines.
• Modern optics-ready models.

Cons

• Ammo will cost more, and is harder to find in 9mm.
• The after-market/support ecosystem is much smaller.
• They have a larger footprint than many compact carry weapons.

2. Ruger-57

The Ruger-57 is a 5.7×28 mm pistol designed to be affordable and appear to be “traditional,” which automatically sets itself apart from the FN Five-seveN. Ruger began producing it in December 2019 and promotes it as an affordable pistol option in this caliber.

You will find light felt recoil, and it is easy to follow up between strings of fire; ergos favor controllability for rapid fire. One of the key features is the 20-round magazines or, in the case of certain states, 10-round magazines. It is also available in a threaded barrel as an option on certain Ruger-57 variants.

The sights feature a long sight radius with an adjustable rear sight and a fiber-optic front sight, and the barrel measures 4.94 inches. In terms of accuracy, I’ve used the Ruger-57 with quality ammo, and it easily produces very tight groups at home defense and even extended pistol distances. Reviews report very good practical accuracy for a service pistol.

Specifications

Caliber: 5.7×28 mm.

Action: Delayed-blowback.

Barrel length: 4.94 in.

Overall length: 8.65 in (approx).

Unloaded weight: ~24.5 oz.

Magazine: 20+1 (standard); 10+1 state models available.

Sights / Optics: Fiber-optic front, adjustable rear; optic-mounting plate (adapter available).

Extras: Picatinny rail; threaded-barrel accessory availability.

Pros and Cons

Pros

• Very low felt recoil — fast follow-ups and easy control.
• Standard 20-round capacity in a pistol-style package.
• Ergonomic grip and long sight radius with adjustable/fiber-optic sights.
• Threaded-barrel and optic-mount options for added versatility.

Cons

• 5.7×28 ammo is pricier and less available than common calibers.
• Larger footprint than compact carry pistols.
• Some loads produce more muzzle flash/noise than 9mm.
• Aftermarket parts/support smaller than the 9mm ecosystem.

3. PSA 5.7 Rock

In 2022, Palmetto State Armory launched the PSA 5.7 Rock, which is an accessible full-size 5.7×28 mm pistol featuring modern (optics-ready, threaded variants) components that somewhat replicate FN and Ruger’s similarities.

Low felt recoil, quick follow-up shots, plus reliable operation with modern 5.7 ammunition have made it a credible, user-friendly, solid range and duty option at a reasonable cost.

The flat 5.7 trajectory, combined with its long barrel and sight radius, translates into good practical accuracy. I found it would create a nice, tight cluster with appropriate ammunition and reach typical, defensive, reasonable limits (reasonableness dictated by trigger and ammunition).

Specifications

Caliber: 5.7×28 mm.

Action: Delayed-blowback, striker-fired single-action.

Barrel length: ~5.0–5.2 in (full size).

Overall length: ~8.7–8.75 in.

Weight (empty): ~25 oz (full size).

Magazine: 23+1 (full); compact 21+1 variants exist.

Sights / Optics: Glock-style sights; optics-ready slides available.

Extras: Fluted carbon-steel barrel, Picatinny rail, threaded-barrel options, ambi mag catch.

Pros and Cons

Pros

• Very low felt recoil → easy control and fast follow-ups.
• High factory capacity (23 rounds) in a slim frame.
• Feature-rich for the price: optics-ready, threaded barrels, flared magwell.
• Competitive price vs FN and others.

Cons

• 5.7 ammo, still costlier / less common than 9mm.
• Full-size footprint may be large for concealed carry.
• Trigger and ergonomics are good, but not class-leading.
• Aftermarket support is smaller than mainstream 9mm platforms.

4. Smith & Wesson M&P 5.7

The Smith & Wesson launched the M&P 5.7 in 2023, becoming the first major manufacturer to produce a factory 5.7×28 mm pistol, adding to the now larger list of manufacturers making offerings in the cartridge.

Utilizes a rotating “TEMPO” barrel / gas-assisted design to help manage recoil; provides very light felt recoil with fast follow-ups and great reliability with modern 5.7 loads.

The combination of long barrel length, optic-ready slide, and slim grip provides good practical accuracy — reviewers have reported consistent two-inch groups (or better) at short ranges with quality ammo.

Specifications

Caliber: 5.7×28 mm.

Barrel length: ~5.0 in (threaded 1/2-28).

Action: Hammer-fired, single-action with rotating TEMPO/gas-assist barrel.

Magazine capacity: 22+1 (common configuration); 10-round options for restricted states.

Overall length: ~8.7–8.75 in.

Weight (empty): ~24–26 oz (varies by config).

Sights / Optics: Optic-ready slide; flat-face trigger; Picatinny rail.

Pros and Cons

Pros

• Minimal felt recoil → quicker, manageable follow-ups.
• Factory threaded barrel and optic-ready slide add additional capability.
• Excellent factory capacity (22rds) and a narrow grip.
• Reviewers have reported solid reliability out of the box.

Cons

• Full-size frame — not great for deep concealment.
• 5.7×28 as a caliber is still more expensive and less available compared to 9mm.
• Aftermarket components and support for customization are still limited compared to the 9mm platforms.

5. Kel-Tec PR57

The Kel-Tec released the PR57 in 2025 as an ultra-light, unconventional 5.7×28 mm carry pistol with a top-loading/stripper-clip internally fed magazine and a rotary/short-barrel configuration.

The felt recoil is extremely light and follow-ups are very fast; it is loud from a short barrel, but completely manageable and designed for comfortable concealed carry.

Very usable for self-defense and close/medium ranges, it is tight/repeatable inside ~25 yards; however, long-range tightness and precision are limited by the trigger and short barrel.

Specifications

Caliber: 5.7×28 mm.

Feed system: Internal 20-round magazine fed by 10-round stripper clips.

Barrel length: ~4.0–4.64 in (model/config).

Overall length: ~7.16 in.

Unloaded weight: ≈13.86 oz (≈393 g).

Capacity: 20+1 (standard).

Sights / Optics: Fixed/drift-adjustable sights; optic plate on some variants.

Pros and Cons

Pros

• Very lightweight – convenient to carry all day.
• 20 rounds in a very compact package.
• Unique top-loading/stripper clip system that speeds reloads and does not require removable magazines.
• Competitive MSRP versus other 5.7 pistols.

Cons

• Very loud muzzle blast and barrel flash from a short barrel.
• Potentially impractical internal mag/stripper clip system for those who prefer detachable magazines.
• Limited after-market compared to FN/Ruger/PSA platforms.
• Short-barreled limits longer ballistic performance compared to longer FN/Ruger/PSA platform 5.7 pistols.

Final Thoughts

The 5.7×28 mm pistols appeal with light recoil, flat trajectory, and high capacity. Each model offers something special to the 5.7 family — the FN Five-seveN for history and reliability, the Ruger-57 for price performance, the PSA Rock for price, the M&P 5.7 for its strange magazine design, and the Kel-Tec PR57 for ultra-light carry.

Cost of ammo and availability are still considerations, but these pistols offer fast, accurate shooting and modern performance that make the 5.7×28 mm caliber a legitimate consideration.

FAQs

Who makes the best 5.7 pistol?

Subjective — FN Herstal’s Five-seveN is widely regarded as the flagship, but Ruger, Smith & Wesson, PSA, and Kel-Tec each make strong, purpose-driven options.

What is the best 5.7 pistol?

Depends on your priority: FN Five-seveN for proven refinement, Ruger-57 for a familiar/value package, PSA 5.7 Rock for features-per-dollar, M&P 5.7 for engineering/threads, and Kel-Tec PR57 for ultra-light carry.

Why is 5.7 so expensive?

Ammo costs more because demand is lower, production runs are smaller, bullets/primers and specialized tooling are optimized for a niche cartridge, and logistics/market premiums raise retail prices versus common calibers like 9mm.

How many rounds does an FN 5.7 hold?

Standard factory magazines are 20 rounds (10-round versions exist for restricted jurisdictions); FN also offers 10-round magazines where required.
