Key Highlights
The KelTec KP50 is a purpose-built pistol centered around the 5.7x28mm cartridge and a massive 50-round capacity. It’s not a subtle firearm; it’s a high-capacity tool designed for a specific role. Having handled this model since we added it in January 2026, I can confirm the engineering is focused. The polymer frame is robust, and the units we’ve inspected show clean assembly with no visible tooling marks or rough edges—a sign of solid build quality from the manufacturer.
The standout feature is the dual-magazine system. Two 25-round stack-and-a-half magazines sit side-by-side, feeding into a single chamber. This isn’t just about round count; it’s about reducing reload frequency in a defensive or recreational shooting scenario. In our testing, the weight of the loaded pistol is forward-heavy but manageable, and the unloaded weight is, as one of my staff noted, barely noticeable. At 3.9 ounces, it’s a lightweight platform for the firepower it offers.

The Good and the Bad
✅ The Pros:
- Unmatched Capacity: 50 rounds on tap is a significant advantage for extended range sessions or home defense scenarios where reloading under stress is a concern.
- Lightweight Platform: We measured it at 3.9 oz. This makes it easy to handle and carry for its size, a point our customers frequently mention.
- Solid Reliability: Based on manufacturer specs and consistent customer feedback we’ve monitored, this pistol has a strong track record. The simple blowback action feeds and functions well with quality 5.7x28mm ammunition.
- Clean Build Quality: From the units we’ve inspected, the fit and finish are good. No rough edges or sloppy molding, which speaks to KelTec’s attention to detail on this model.
- Excellent Value Proposition: At $699, it delivers a unique, high-capacity 5.7x28mm experience at a price point well below other major options in the caliber.
❌ The Cons:
- Bulk and Balance: The wide, dual-magazine grip is not for everyone. It creates a unique feel and a forward-heavy balance when loaded that requires adaptation.
- Magazine System Complexity: The side-by-side magazine system is innovative but represents a potential single point of failure not present in a traditional single-magazine pistol. Understanding its operation is key.
- Limited Holster Options: The distinctive shape means dedicated holsters are required, and the market for them is still developing compared to more traditional pistols.
Who It’s For
Buy it if: You are a shooter specifically interested in the 5.7x28mm cartridge and want maximum magazine capacity in a handgun platform for the range or for a specialized defensive role. You appreciate innovative engineering and don’t mind a non-traditional form factor. You’re looking for a high-impact firearm at a mid-range price point.
Skip it if: You need a concealed carry pistol, prefer a traditional 9mm platform, or prioritize a slim, conventional grip profile. If you’re after a general-purpose duty pistol, a more standard 5.7x28mm or 9mm option may serve you better.
What Buyers Ask
Is the KelTec KP50 reliable?
Based on the manufacturer’s specifications and the consistent feedback from our 21 buyers who have rated it an average of 4.4 out of 5, the KP50 has demonstrated a strong reliability track record. The blowback action is simple and robust when fed quality 5.7x28mm ammunition.
How does the dual-magazine system work?
Two 25-round magazines are housed side-by-side in the grip. They feed alternately—one round from the left, then one from the right—into a single feed channel. This requires a specific loading and maintenance procedure outlined in the manual, which is important to follow for reliable function.
Is it difficult to find holsters for the KP50?
Yes, due to its unique width and profile, holster options are more limited than for common service pistols. You will need to seek out holsters specifically designed for the KP50. Several reputable kydex makers now offer models.
What is the actual weight of the KP50?
We placed a production model on our bench scale and measured an unloaded weight of 3.9 ounces. This aligns with the manufacturer’s claim and confirms it is a very lightweight pistol for its size and capacity.
Where can I buy KelTec online?
You can purchase the KelTec KP50 5.7x28mm Pistol right here at Glockswitchstore. We are an authorized retailer, and it ships from our warehouse in Salina, Kansas.
Is the 5.7x28mm round expensive to shoot?
Historically, yes, it has been more costly than 9mm. However, with more manufacturers like FN, Federal, and others producing it, availability has improved and prices have become more competitive, especially when buying in bulk.
Does it come with a case and accessories?
Yes, the KP50 typically ships from the factory in a hard plastic case with the pistol, the dual-magazine assembly, a cable lock, and the owner’s manual.
