Saturday at the Movies: 5.7x28mm Handguns and Ammo Tests

This Saturday Movie showcase features four handguns chambered for the modern, high-velocity 5.7x28mm cartridge. In a 5″-6″ barreled pistol, the 5.7x28mm round can achieve very high velocities compared to a 9x19mm (9mm Luger) or .40 SW. The bottle-necked 5.7×28mm cartridge weighs roughly two-thirds as much as a typical 9mm Luger cartridge, allowing more rounds to be carried for the same weight. The cartridge can produce considerable muzzle flash when fired from a pistol, but it has roughly 30% less recoil than the 9mm Luger cartridge, improving controllability. Thanks to its high velocity, the 5.7×28mm has a flatter trajectory than most pistol ammo types.

Today we showcase videos of four different 5.7x28mm pistols — the new S&W M&P 5.7, the PSA 5.7 Rock, the Ruger-5.7, and the FN Five-SeveN Mk3 MRD. If you are looking for the best deal on a 5.7 pistol, check out the the PSA 5.7 Rock. You can buy one today for $599.99 including Holosun Red Dot Sight.

Smith & Wesson M&P 5.7 with 22-Rd Magazine

Chambered for the high-velocity, flat-shooting 5.7x28mm, the Smith & Wesson M&P 5.7 features S&W’s new TEMPO barrel system. This is a two-part, lock-breech barrel with a proprietary gas system for improved cycling and extraction. The new M&P 5.7 includes a 1/2×28 threaded barrel to mount a muzzle device or suppressor, optics-cut slide, flat-face trigger, and forward, frame rail for mounting accessories.

PSA 5.7 Rock — Best Value in a 5.7x28mm Handgun

The Palmetto State Armory (PSA) 5.7 Rock is the best value in a 5.7x28mm pistol. Right now PSA offers it complete with a mounted Holosun Red Dot sight for just $599.99 with two 23-rd mags. A full-sized, polymer-framed pistol, the PSA 5.7 Rock has threaded carbon steel fluted barrel and 416 stainless steel slide with QPQ finish for corrosion protection. Chambered in 5.7x28mm, the PSA 5.7 Rock is fed from a 23-round magazine and operated by a smooth, single-action, striker-fired trigger mechanism. While sold with a Holosun 407k optic, the 5.7 Rock slide accepts other Shield footprint optics.

Ruger-5.7 Pistol Review by Hickok45

In the video above, popular YouTube host Hickok45 reviews the Ruger-5.7, which was introduced in late 2019. This gun has proven reliable and when it hit the market it was much less expensive than its main competitor made by FN. Ruger’s 5.7x28mm pistol is blow-back operated with an internal hammer and ambidextrous thumb safety. The pistol is offered with a 20+1 capacity magazine and an adjustable rear sight paired with a fiber-­optic front. Current MSRP is $899.00.

FN Five-SeveN Mk3 MRD Review

In this episode of TFBTV, James Reeves reviews the new FN Five-SeveN Mk3 MRD. At $1,449.00 MSRP, this is the most expensive 5.7x28mm pistol on the market, but might it also be the best? James takes the new Five-seveN Mk3 MRD to the range and to the table to tell you if FN’ lastest, high-tech 5.7x28mm pistol is worth the spend.

Comparison Between 5.7x28mm and 9x19mm

In this video James Reeves compares the performance of the 5.7x28mm round with the 9mm Luger. The 5.7x28mm round certainly offers higher velocity and greater penetration than the legendary 9mm round. Plus common 5.7 magazines hold over 20 rounds. James discusses the advantages of this modern 5.7x28mm cartridge, as well as a few of its shortcomings — such as high cost per round. There is another insightful comparison between the two ammo types on the Ammo-to-Go website. Editor John Lewis notes: “5.7×28 is lighter and faster than 9mm ammo” while the 9mm had a “slight advantage in energy [and was] much better in gel”.

5.7x28mm vs 9mm Penetration Test

In this video the tester shot both 9mm and a 5.7x28mm bullets into horizontal stacks of paper plates. The smaller-diameter 5.7mm bullet penetrated about 40% more paper plates than the 9mm bullet (See video at 3:10-3:35). The 5.7mm bullet basically retained its dimensions in this test, while the hollow-point 9mm spread out slightly. Just mere horizontal penetration can’t tell you the actual effectiveness of the round based in a defensive situation. In a different test using Ballistic Gel, both rounds penetrated adequately but the 9mm created a bigger wound channel. SEE: AmmotoGo.com 5.7x28mm Test.

Short History of 5.7x28mm Guns and Ammo

The FN 5.7×28mm (designated as the 5.7×28 by the C.I.P. and FN 5.7x28mm NATO) is a small-caliber, high-velocity, rebated rim, bottle-necked centerfire cartridge designed for handgun and personal defense weapon uses. It is similar in length to the .22 WMR and somewhat similar to the .22 Hornet or .22 K-Hornet. Unlike many new cartridges, it has no parent case — it was developed from scratch by FN.

The 5.7×28mm was developed in conjunction with the FN P90 PDW and FN Five-Seven pistol in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge (9mm Luger). In 2002 and 2003, NATO conducted a series of tests with the intention of standardizing a PDW cartridge as a replacement for the 9×19mm. The tests compared the relative merits of the 5.7×28mm cartridge and the 4.6×30mm cartridge, which was created by Heckler & Koch.

By 2006, FN’s 5.7×28mm firearms — the P90 PDW and Five-Seven pistol — were in service with military and police forces in over 40 nations worldwide. In the USA, 5.7×28mm firearms are currently used by many law enforcement agencies, including the U.S. Secret Service.

Along with use in military and law enforcement firearms, in recent years the 5.7×28mm cartridge has become popular for handguns in the USA. In December 2019 Ruger unveiled the Ruger-5.7 semi-automatic pistol chambered in this cartridge. In January 2021 Kel-Tec introduced its P50 handgun, which uses horizontal 50-round FN P90 magazines. In January 2021 Palmetto State Armory (PSA) introduced its Rock 5.7 pistol. And this year, Smith & Wesson has released its new M&P 5.7, featured above.

The 5.7×28mm cartridge itself is produced by multiple ammunition makers including Federal, Fiocchi, FN, and Speer. 5.7x28mm ammunition is PRICEY — the cheapest 5.7x28mm ammo we found with a quick search was 40gr Federal American Eagle at $0.77 round. By comparison, you can currently find bulk CCI 9mm Luger ammo for $0.30/round.
