Estimated studying time: 9 minutes
After I attended the 5.7 Fest final yr to study concerning the capabilities of 5.7x28mm ammunition, I ran 150 rounds of 5.7x28mm ammunition by means of the Tisas PX-5.7 semi-automatic pistol. It proved itself a stable, dependable firearm throughout my taking pictures.
Then, I watched two different occasion members blast off 500 rounds by means of one of many PX-5.7’s that already had lots of of rounds shot by means of it. The pair of shooters stored slapping in full mags and firing them off. In seven minutes of regular taking pictures, they burned by means of the five hundred rounds; the pistol skilled zero malfunctions and pictures have been persistently on course.
Positive, the top of the PX slide and barrel have been sizzling sufficient to second-degree burn your pores and skin. Anticipated. However the gun itself functioned superb.
Impressed, I requested Jahred Gamez of SDS Arms, who additionally attended the 5.7 Fest and had invited me to the occasion, if I may get a PX-5.7 to check and consider for a evaluate. SDS Arms is the only real importer of this pistol. No, he stated.
“We’ve got a brand new model arriving quickly,” Gamez defined. “The PX-5.7 OR, an optics prepared mannequin, and I’d prefer to ship that one to you. Okay?”
Okay!

Chambered in 5.7x28mm, the pistol featured a 4.80-inch metal barrel with a glossy black end, and a carbon metal slide. Poly framed and striker fired, the pistol sported each an adjunct rail below the barrel and a beavertail on the rear for consolation and management whereas taking pictures. Black, interchangeable backstraps have been included for a extra tailor-made match.

Optics prepared, however the open sights labored superb for me on the 5.7 Fest. The fiber optic entrance sight offered fast goal acquisition, whereas the rear blade notch was beneficiant and lined up with the fiber optic dot rapidly.
Ammunition capability is 20+1. With an additional journal available, that’s 41 rounds. Want extra ammo? Higher get a SAW.

The PX-Tisas magazines have been metal, with spherical cutouts alongside the edges.
ZeroTech Choice
An OR mannequin pistol required an optic.
I chosen the Thrive HD 1×21 Micro Reflex Sight made by ZeroTech Optics. The Thrive HD featured a 3 MOA pink dot and 10 brightness ranges, operated on one CR2032 battery and was constructed on the RMSc optic footprint. Waterproof and fog-proof, the optic’s elevation and windage controls offered 60 MOA of changes every.

To mount the ZeroTech, I eliminated the optic cowl plate on the rear of the pistol slide utilizing the Tisas-provided torque wrench. This revealed the RMSc lower to the slide; the Thrive HD match proper onto the lower.
Of word, Tisas additionally equipped an adapter plate for an RMR foot-printed optic.
5.7 Ammo
I used quite a lot of 5.7×28 ammo manufacturers.

I ran Federal Ammunition American Eagle loaded with a 40 grain, full steel jacket (FMJ) bullet. Plus, I used Fiocchi USA Hyperformance, and a 35-grain jacketed frangible, and Fiocchi USA Hyperformance and a 40-grain tipped hole level.
Additionally included have been Hornady Important Protection, 40 grain FTX poly tipped bullet, and Speer Ammunition Private Safety, 40 grain Gold Dot hole level.
Taking pictures with My PX-5.7 and a Thrive HD
At my out of doors vary, the Thrive HD zeroed rapidly.
For my accuracy testing, I shot at seven yards offhand and at 20 yards from a relaxation. On the seven-yard mark, all the 5.7 ammo manufacturers pegged 5 shot teams at 1.0 inches and below. There have been bigger teams, in fact, as much as 1.5-inches, and I credited these to myself.
Whereas the pistol and the varied ammo manufacturers all matched up properly, the PX-5.7 OR and the Fiocchi Hyperformance 35 grain hundreds liked one another. My finest 5 shot teams with this load got here in at simply .60 inches.

At one level, I had the primary 4 rounds of 35 grain Hyperformance touching, later measured at .40-inches, after which I choked and pulled shot #5 for a complete group of .85-inches. Rattling!

The Hornady Important Protection and the 40-grain Hyperformance made .90-inch teams, too.
At 20 yards and a relaxation, all the ammo manufacturers produced 5 shot teams of two.5- to three.0-inches. I had 9 rounds of Hornady Important Protection left in a single field, shot off all 9 at this distance and so they made a 2.4-inch group.

As soon as once more, Fiocchi’s 35-grain spherical topped all others, with 10 pictures at simply 1.9 inches.

Apparent conclusion: with these 5.7×28 ammo manufacturers, the PX-5.7 OR is greater than correct sufficient for self- and home-defense, plinking and varmint management.

Different PX-5.7 Options
As centerfire handgun rounds go, recoil shoving again into the hand and laborious isn’t a priority with the 5.7×28. However given its comparatively excessive velocity, within the neighborhood of 1,800 ft per second on the pistol’s muzzle, snappy muzzle rise happens, particularly when hammering out pictures.

The PX-5.7 OR dealt with this muzzle rise potential superb because of deep texturing on the poly grips and a properly undercut set off guard. The pronounced beavertail on the rear of the body added to my stability whereas taking pictures.

The striker-fired set off had a spongy really feel, however the flat-faced set off did easy out the three.0-pound set off pull.

Gamez tells me SDS Arms is importing a fair newer model of the PX-5.7 OR quickly, this one with a threaded barrel to be used with a suppressor. Which ought to present one other high quality possibility for this caliber and at an affordable worth.
