Grip and Controls

The PSA 5.7 Rock boasts impressive ergonomics, with a comfortable grip that fits well in your hand. The grip texture is designed to provide a secure hold, ensuring that the pistol stays in your hand during recoil. Texturing on the grip frame adds to this secure feel, alongside a prominent beaver tail to protect your hand from slide bite. This beaver tail allows for a low bore axis, which improves control and accuracy, especially during rapid fire.

The controls on the PSA 5.7 Rock are easily accessible and placed in intuitive locations. This means you won't have to fumble around to find the controls when you need them. The slide release, magazine release, and any necessary safety features are all easily within reach, allowing for a seamless operation experience.

Weight and Balance

Weighing in at 25 oz, the PSA 5.7 Rock is light enough to be carried comfortably but still maintains enough heft to help manage recoil effectively. Combined with its ergonomic design and low bore axis, the weight and balance of this pistol make it a pleasure to shoot. The overall stability will enhance your shooting experience, providing an optimal blend of comfort and performance.

With its smart design and ergonomic features, the PSA 5.7 Rock presents an excellent option for those looking to add a 5.7x28mm pistol to their arsenal. The comfortable grip and easily accessible controls, along with its weight and balance, ensure a seamless and enjoyable shooting experience.

Barrel, Slide and Frame

Material and Finish

The PSA 5.7 Rock features a carbon steel fluted barrel which provides a combination of durability and efficient heat dissipation. The barrel length is 5.2 inches, which ensures a high level of accuracy. For those looking for a more customized appearance, a threaded barrel option is available.

The slide of the PSA 5.7 Rock is made from 416 stainless steel which offers a good balance between strength and corrosion resistance. It is finished with a QPQ (Quench Polish Quench) treatment which further enhances its durability and resistance to wear.

Slide Serrations

The PSA 5.7 Rock's slide features slide milling, ensuring a positive grip when manipulating the slide. These serrations are designed to provide a reliable grip under various conditions.

While the PSA 5.7 Rock does share some similarities with other handguns like the Archon Type B, its carbon steel fluted barrel, 416 stainless steel slide, and QPQ finish make it a unique offering in the 5.7x28mm platform.

When using your PSA 5.7 Rock, you can be confident in its durable materials, well-crafted finish, and functional slide serrations for efficient operation.


Ammo and Magazines 

5.7x28mm Ammo

When it comes to 5.7x28mm ammunition, the PSA 5.7 Rock is designed to handle this relatively niche, high-velocity round. While the available ammo can be more expensive than traditional 9mm or .45 ACP, its performance offers advantages such as minimal recoil and impressive terminal ballistics. Be prepared to invest more in ammunition for the Rock 5.7, but as a trade-off, you'll experience the unique benefits of this caliber.


The PSA 5.7 Rock uses standard-capacity magazines, with a capacity of 23 rounds. This provides ample firepower for both range sessions and personal defense scenarios. These 5.7 Rock double-stack magazines ensure that you have enough ammunition on hand when you need it most.

Trigger and Safety Features

Striker-Fired System

The PSA 5.7 Rock is a striker-fired pistol, which means it utilizes a striker mechanism instead of a traditional hammer. This system is known for providing a consistent trigger pull and a faster lock time, which can result in better accuracy. You can appreciate the simplicity and reliability of this system, as it has fewer parts and is easier to maintain compared to a hammer-fired system.

Trigger Feel

One of the essential aspects of any handgun is the trigger feel. With the PSA 5.7 Rock, you can expect a smooth single-action trigger mechanism that offers a clean and crisp break. This allows you to have better control over your shots, contributing to improved accuracy and consistency. Furthermore, the trigger is designed with a short reset, enabling you to fire quick follow-up shots with ease.

Safety Mechanism

When it comes to safety, the PSA 5.7 Rock incorporates both trigger and striker safeties. The trigger safety is a common feature in striker-fired pistols, ensuring that the gun will not fire unless the trigger is deliberately pulled. The striker safety, on the other hand, prevents the striker from moving forward and firing the round unless the trigger is fully depressed. These combined safety features provide you with the confidence that your pistol will only discharge when you intend it to, reducing the likelihood of accidental discharges.

Overall, the trigger and safety features of the PSA 5.7 Rock contribute to a reliable and enjoyable shooting experience. Its striker-fired system, smooth trigger feel, and multiple safety mechanisms make it an excellent choice for both experienced and novice handgun enthusiasts.

Sights, Optics and Accessory Rails


The PSA 5.7 Rock comes with standard iron sights that are easy to use and provide a clear sight picture. These sights will serve you well for basic usage and target practice. If you would like to upgrade your sights for better visibility or low light conditions, the PSA 5.7 Rock is compatible with Glock-compatible sights, giving you numerous options for aftermarket sights, such as night sights for improved low light performance.

Optics Compatibility

In case you wish to install a red dot sight on your PSA 5.7 Rock, you have the option to choose an optics-ready version. This version includes a pre-cut slide and mounting plates, allowing you to effortlessly mount a variety of red dot sights on the pistol. This feature increases the versatility of the weapon and makes shooting more enjoyable for those who prefer using red dots over iron sights.

Accessory Rails

Your PSA 5.7 Rock features a Picatinny accessory rail beneath the barrel, which allows you to easily attach accessories such as lights, lasers, or even suppressors with the right adapter. The Picatinny rail is a standard rail system providing compatibility with a wide range of accessories to match your preferences and shooting needs. This rail system offers you the opportunity to customize your pistol for various applications or scenarios while maintaining functionality and ease of use.

Performance and Handling


The PSA 5.7 Rock is known for its accurate performance on the range. With its 5.2" barrel length, featuring a 1/9" twist rate1, you can expect consistent shot placement and tight groupings. The 5.7x28mm caliber not only offers a flat trajectory but also allows for minimal bullet drop at longer distances. As you put the pistol to the test, you'll appreciate its precision and the confidence it instills during your shooting sessions.


One of the key advantages of the PSA 5.7 Rock is its minimal recoil2. Due to the nature of the 5.7x28mm caliber, shooting this handgun is a relatively smooth experience. The manageable recoil means that you can maintain better control, allowing for faster follow-up shots and improved accuracy. This feature not only enhances your range experience but also makes the pistol more enjoyable to shoot for extended sessions.

Range Experience

When you take your PSA 5.7 Rock to the range, you'll immediately notice its ergonomic design and comfortable fit3. The full-sized polymer frame, combined with its 25 oz weight, provides a stable platform for shooting. Additionally, the high-capacity magazine with 23 rounds helps ensure that you can focus on your shooting skills without frequently stopping to reload4.

Despite its many positives, it's important to note that the 5.7x28mm ammunition can be expensive and louder than other calibers2. You might have to account for the increased cost and noise levels during your range sessions. However, the overall performance and handling of the PSA 5.7 Rock make it a worthwhile investment for shooters seeking a reliable and accurate handgun in the unique 5.7x28mm caliber.

  • A 4.8-inch barrel
  • Low recoil
  • Ambidextrous safety switch

Remember to check and comply with local laws and regulations concerning suppressor usage.

416 Steel Slide Professional Milling

The quality of the materials used in the PSA 5.7 Rock is impressive, as it features a durable 416 steel slide. This high-quality steel ensures longevity and reliability while providing a professional milling job. With this steel slide, you can expect your pistol to withstand the toughest conditions and maintain its performance over time.

Furthermore, the slide milling in the PSA 5.7 Rock grants you the ability to mount various optics, such as red dot sights, to enhance your accuracy and target acquisition capabilities. As you customize your handgun, remember to choose compatible gear and follow proper installation guidelines to ensure the best possible performance.

By taking advantage of these available customizations and compatibility options, you can craft a unique and personalized experience with your PSA 5.7 Rock pistol. This will allow you to enjoy the advantages of a threaded barrel and a durable 416 steel slide, while also exploring the benefits of specific accessories that improve your shooting experience.

Cost Considerations

When considering the PSA 5.7 Rock, one of the primary factors to keep in mind is affordability. While this handgun is chambered in the impressive 5.7x28mm cartridge, it comes at a more affordable price of around $499 compared to other options like the FN Five-Seven pistol. This attractive price point might entice you into exploring the world of 5.7x28mm firearms.

However, there are other costs to consider beyond the initial purchase price of the pistol. For example:

  • Ammunition: While the 5.7x28mm round offers significant advantages like high capacity and minimal recoil, the downside is that it can be quite expensive. This means that you can expect to pay more for ammo compared to other popular calibers.
Reasonably Priced

Despite these potential drawbacks, the PSA 5.7 Rock remains a reasonably priced option within the 5.7 handgun market. Its lower price compared to competitors can help offset the higher cost of ammunition.

In addition to the attractive base price, the PSA 5.7 Rock also comes with notable features including good ergonomics and an optics-ready version, which can make the value proposition even more enticing.

Remember when purchasing a handgun, it's crucial to weigh all the cost factors, including the initial investment and the ongoing costs of ammunition and maintenance. While the PSA 5.7 Rock might not be the cheapest option, it offers a solid balance of performance and affordability in the 5.7 pistol market.
