The 90’s are coming back! But in the form of the 5.7×28 round that never really took off. The round is making a comeback in the form of more than just FN guns. The best 5.7 guns have been the same for many years, but recently, companies like Smith and Wesson and Palmetto State Armory are breaking into the market.

Best 5.7x28mm Guns

Here are the current best 5.7x28mm guns on the market today. The options are limited, but 2023 is proving to be the year of the 5.7, so it might be the year of the resurgence of the FN 5.7x28mm.

PS90 & P90

Best 5.7 Subgun the FN PS90

The P90 is an iconic gun and one of my favorites on the list, as I recently got one of my own, made it an SBR, and suppressed it.

Brad even bought himself one and did a full PS90 review, which, for a three-decade-old gun, held its ground.

The 5.7×28 round has been around since the 90s and the P90 was first released in 1990.

It’s extremely fun to shoot and has minimal recoil. One of the significant features of the P90 is the small size of the gun and the ergonomics. It takes some getting used to when holding, but it’s very fluid after you adjust.

FN Five-Seven

FN 5.7 MRD

The FN Five-Seven, typically just called the “5.7” is one of the original guns that FN made to shoot the 5.7x28mm round.

This pistol is also from the 1990s and is nearly all polymer. The gun has recently gone through a revision but the original design is iconic by itself and is known worldwide.

This is hands down the most expensive 5.7×28 pistol on this list and likely because it’s the original. The latest competition will either drive the price down or cement its place at the top.

But other options are bringing the heat by bringing meal frames and threaded barrels included from the factory.

Ruger 5.7

Ruger was one of the first to release a new Ruger 5.7 pistol in December 2019.

While it didn’t have a lot of traction at first, it has since picked up some traction as other major companies, like PSA and S&W have released their 5.7 pistol options.

The Ruger 5.7 has a metal slide and polymer frame and has a very similar feel to the Ruger Security 9 series.

The fiber optic front sight is a really nice touch and it shoots as smoothly as butter spread.

Smith & Wesson M&P 5.7

Fresh off the heels of a Shot Show 2023 launch the S&W M&P 5.7 is somewhat hard to find, but your local gun store just may have it in stock.

Bearing the M&P monicker, this gun falls right in line, albeit a bit larger than the other caliber options available from the S&W M&P line.

CMMG Banshee 5.7

The CMMG Banshee Mk57 is one of the only AR-style guns that chamber the 5.7×28 round.

This may change very soon and my money would be on Palmetto State Armory releasing a Banshee competitor.

I had the pleasure of shooting the Mk57 and it’s an extremely smooth shooting AR style 5.7 and probably one of the only production AR’s chambered in 5.7x28mm.

Keltec P50

The Kel-Tec P50 is a unique-looking gun but takes some of the design features of the PS90. It clearly gets its naming convention from the PS90.

The P50 features a nearly identical round feeding into the gun with a horizontal magazine.

Having that same magazine style makes this gun a very close copy, but with its nearly $1,000 price point, the PS90, with its most iconic look, may be the better option.

About 5.7×28

The 5.7x28mm cartridge is a small-caliber, bottlenecked cartridge designed and manufactured by FN Herstal, a Belgian firearms manufacturer. It was introduced in the early 1990s and was specifically developed for use in the FN P90 submachine gun and the FN Five-seveN pistol.

The cartridge is relatively small, measuring 5.7mm in diameter and 28mm in length. It is a centerfire cartridge with a bottlenecked design, meaning the case is narrower at the base than it is at the neck. The cartridge typically uses a lightweight bullet, with typical weights ranging from 23 to 40 grains.

The 5.7x28mm cartridge has a relatively high velocity and flat trajectory, making it suitable for close-quarters combat and longer-range engagements. It is also known for its low recoil, which makes it easier for shooters to maintain accuracy and control.

In addition to its use in the FN P90 and Five-seveN, the 5.7x28mm cartridge has also been used in other firearms, such as the FN PS90 carbine and the Ruger 57 pistol. It has also gained popularity among civilian shooters due to its unique characteristics and relatively low recoil.

Some of the best ammo on the market today is still the FN-branded 5.7×28 blue tip. But for plinking or range ammo, there are plenty of options here are a few of the best 5.7x28mm ammo options right now.

Why is 5.7×28 making a comeback?

With more companies making models it’s coming back to the forefront of people’s minds and the impressive ballistics is why people are reconsidering the round.

There is also a number of ammo companies who have doubled down on their ammo production for the 5.7x28mm round, including PSA’s America Ammo Company.
