About this product
What is the Kel-Tec PR-5.7 5.7x28mm 4.64 in Pistol? It's a striker-fired semi-auto chambered in 5.7x28mm with a 4.64-inch barrel, utilizing a top-loading rotary-barrel system that accepts stripper clips instead of traditional magazines. The polymer frame and optic-ready slide prioritize lightweight carry, while the fixed three-dot sights and ambidextrous safety offer straightforward operation. With an overall length of 7.16 inches and drilled receiver, it's designed for shooters seeking an alternative to conventional handguns.
What is the Kel-Tec PR-5.7 used for?
It's primarily a concealed carry pistol optimized for lightweight, rapid deployment in self-defense scenarios. Chambered in 5.7x28mm, it delivers high velocity and flat trajectory, making it effective at intermediate ranges up to 50 yards. The top-loading system allows quick reloads with stripper clips, ideal for users who prioritize simplicity over high-capacity magazines.
How does the Kel-Tec PR-5.7 compare to a Ruger-57?
The Kel-Tec PR-5.7 is lighter at 24 ounces versus the Ruger-57's 27.5 ounces, but the Ruger-57 offers a higher capacity of 20 rounds compared to the PR-5.7's stripper clip system. The PR-5.7's rotary barrel reduces recoil more effectively, while the Ruger-57 has a more conventional magazine feed for faster reloads. For rapid magazine changes, the Ruger-57 is superior, but the PR-5.7 excels in recoil management and portability.
What does it weigh and what are the dimensions?
It weighs 24 ounces with an unloaded weight of 1.5 pounds, measuring 7.16 inches in overall length and 4.64 inches in barrel length. The height is 5.12 inches, and width is 1.2 inches, making it slimmer than many full-size pistols. These dimensions contribute to its ease of concealment and handling in tight spaces.
Who is this NOT for?
This pistol is not for shooters who prioritize high magazine capacity or rapid reloads, as it uses stripper clips instead of detachable magazines. It's also unsuitable for those preferring heavier calibers like 9mm or .45 ACP for stopping power. If you need a high-round count for competition or duty use, consider a the Stevens 334 Rifle instead.
What's in the box?
The box includes the pistol, two stripper clips, an optics plate for mounting red dots, and a user manual. Total package weight is 3 pounds, with the pistol accounting for 24 ounces of that. No cleaning kit or additional accessories are included, so plan to purchase those separately.
Is the Kel-Tec PR-5.7 worth it at $399.99?
Yes, at $399.99, it offers good value for a unique design in the 5.7x28mm niche, though it lacks the magazine convenience of alternatives. The price is competitive with other pistols in this caliber, such as the Ruger-57 at around $650, making it a budget-friendly option. For those interested in shotguns, the Stevens 555 Sporting O/U provides a different type of firearm at a similar price point.

Frequently asked questions
- Is it compatible with suppressors?
- No, the Kel-Tec PR-5.7 is not threaded for suppressors, so direct mounting isn't possible without aftermarket modifications. You'd need a gunsmith to thread the 4.64-inch barrel, which adds cost and time. Check local NFA regulations before attempting any modifications.
- Does it fit in a standard holster?
- No, due to its unique top-loading design and dimensions, it requires a custom holster. Most holsters for similar-sized pistols won't accommodate the 7.16-inch length properly. Brands like Alien Gear may offer compatible options, but expect a 2-3 week lead time for delivery.
- How long does shipping take?
- Shipping typically takes 3-5 business days for in-stock items, but allow up to 10 days for processing and delivery. Expedited options are available for an additional fee. Always confirm with the retailer at purchase.
- Can I return it if it doesn't fit my needs?
- Yes, returns are accepted within 30 days of purchase if the item is unused and in original packaging. A restocking fee of 15% may apply, and you'll need to cover return shipping costs. Contact customer service for a return authorization number first.
- Does this work with common 5.7x28mm ammunition?
- Yes, it's designed for standard 5.7x28mm rounds from brands like FN Herstal or American Eagle. Avoid +P or reloads to prevent wear on the rotary barrel system. Always test with a few rounds first to ensure reliability.
