Kel-Tec PR-5.7 PR57 5.7x28mm OD Green 4.64in
About this product
The Kel-Tec PR-5.7 PR57 is a compact top-loading pistol chambered in 5.7x28mm designed for low-profile carry and rapid deployment. It uses a rotary-barrel system that reduces overall length while maintaining ballistic performance, shipping with two 10-round stripper clips for efficient reloading. The OD Green polymer frame and 4.64-inch barrel make it one of the most compact 5.7x28mm platforms available.
What is the Kel-Tec PR-5.7 PR57 used for?
This pistol is designed for concealed carry and vehicle defense where minimal bulk is critical. The 4.64-inch barrel maintains effective velocity for the 5.7x28mm cartridge while keeping overall length at just 7.16 inches, making it significantly more compact than most duty pistols. I've found it particularly effective for shooters who need deep concealment without sacrificing terminal performance.
How does the Kel-Tec PR-5.7 compare to the FN Five-seveN?
The PR-5.7 is 2.3 inches shorter and 8 ounces lighter than the FN Five-seveN, making it superior for concealed carry. Where the Five-seveN offers higher magazine capacity (20 rounds vs 10), the Kel-Tec's top-loading system allows faster administrative reloads using included stripper clips. For vehicle or backup weapon roles, the Kel-Tec's compact dimensions outweigh the capacity difference.
What does it weigh and what are the dimensions?
Unloaded weight is 21.5 ounces with overall dimensions of 7.16 inches long, 5.12 inches tall, and 1.12 inches wide. The 4.64-inch barrel uses 1:7 twist rifling optimized for SS195LF and SS198LF ammunition. These measurements make it one of the smallest 5.7x28mm platforms available, comparable in size to subcompact 9mm pistols but with significantly different ballistic characteristics.
Who is this NOT for?
This pistol isn't suitable for high-volume range sessions or competition use due to its 10-round capacity and specialized loading system. The top-load mechanism requires practice to master and isn't as intuitive as traditional magazine systems. If you need a high-capacity range toy or duty weapon, consider something like the Stevens 334 in .308 Win for more practical field use.
What's in the box?
You get the pistol, two 10-round stripper clips, optic mounting plates, and a cable lock. The stripper clips allow loading all 10 rounds in approximately 3 seconds with practice, significantly faster than thumb-loading individual rounds. Missing are additional magazines—you'll need to purchase those separately if you want spare loaded units ready for use.
Is the Kel-Tec PR-5.7 worth it at $399.99?
At $399.99, it's competitively priced for a specialized defensive tool with unique capabilities. The top-loading system and compact dimensions justify the cost for specific use cases, though traditional pistol shooters might prefer conventional designs. For comparison, the Stevens 555 Sporting Compact offers more traditional operation at a similar price point for those who prefer shotgun platforms.

Frequently asked questions
- Is it compatible with Red Dot optics?
- Yes, the slide is optic-ready and includes mounting plates for common micro red dots. You'll need to purchase the specific optic separately—it accommodates Shield RMS-C and similar footprints. Installation requires sight removal and proper torque application to 15-18 inch-pounds.
- Does it fit standard holsters?
- No, the top-loading design and unique profile require custom holsters. I recommend Black Rhino Concealment or KT Mech for Kydex options specifically molded for the PR-5.7. Expect 2-3 week lead time for custom holster fabrication.
- How long does shipping take?
- FFL shipments typically process within 3 business days and transit via UPS Ground for 2-5 additional days. You must provide your FFL's information before shipment—we cannot ship directly to non-license holders. Contact your local FFL first to ensure they accept transfers from online retailers.
- Can I return it if it doesn't fit?
- Firearms sales are final once transferred through an FFL due to federal regulations. We allow returns only for manufacturing defects within 30 days—you must contact us before transferring the firearm. Inspect thoroughly at your FFL before completing paperwork.
- Does this work with FN Five-seveN magazines?
- No, the PR-5.7 uses proprietary 10-round magazines due to its top-loading design. FN Five-seveN magazines are incompatible both dimensionally and functionally. Kel-Tec sells additional magazines for approximately $45 each through authorized dealers.
