Key Features
- Optic-Ready Picatinny Rail – Mount any red dot or reflex sight directly to the receiver without adapters. Why it matters: you can fine-tune your sight picture fast, whether you’re punching paper or ringing steel.
- PS90-Style 50-Round Magazine – Uses the same reliable, high-capacity magazines as the FN PS90 carbine. Why it matters: you spend less time reloading and more time shooting, and mags are widely available.
- Ambidextrous Manual Safety – Safety lever on both sides of the frame. Why it matters: left-handed and right-handed shooters can both operate it without breaking their grip.
- Integrated Quick-Detach (QD) Ports – Built-in sling attachment points on the frame. Why it matters: you can sling the pistol for easy carry between stations or while hiking to the range.
- Threaded Barrel (1/2×28) – Factory threads let you add a compensator or suppressor. Why it matters: reduces muzzle rise and noise, making follow-up shots faster and more comfortable.
Who It’s For
This pistol is for the shooter who wants something different from the usual 9mm or .45 ACP. If you enjoy a flat-shooting, low-recoil cartridge that reaches out to 100 yards with ease, the P50 fits the bill. It’s ideal for range days, steel challenge matches, and plinking sessions where capacity and modularity matter. Bird hunters who like to practice with a handgun will appreciate the light recoil and high magazine capacity for drills.
Pros & Cons
- Pro: Extremely low recoil – the 5.7x28mm cartridge is a dream for shooters recovering from wrist injuries or arthritis.
- Pro: 50-round magazine means fewer reloads and more time on target.
- Pro: Fully ambidextrous controls for lefties and righties alike.
- Con: The grip angle is a bit steep for some shooters, and the trigger pull is heavier than a custom 1911 – about 7-8 lbs out of the box. A trigger upgrade can help if you’re used to match triggers.
Comparison

|---|---|---|---|
| Caliber | 5.7x28mm | 5.7x28mm | 5.7x28mm |
| Magazine Capacity | 50 rounds | 20 rounds | 23 rounds |
| Optic Ready | Yes (Picatinny) | Yes (RMSc) | Yes (RMR) |
| Threaded Barrel | Yes (1/2×28) | Yes (1/2×28) | Yes (1/2×28) |
| Weight | 3.6 lbs | 1.7 lbs | 1.8 lbs |
| Price (approx) | $791 | $699 | $549 |
The Ruger-57 is lighter and more concealable, but you get only 20 rounds. The PSA Rock 5.7 is budget-friendly and also lightweight, but its magazine capacity is less than half the P50’s. The Kel-Tec P50 is the clear winner if you want maximum firepower and a modular platform for optics and accessories.
FAQ
Does the Kel-Tec P50 come with a case or any accessories?
Yes, it ships in a hard case with two 50-round PS90-style magazines, a cable lock, and an owner’s manual. You’re ready to hit the range as soon as you pick it up.
What kind of optic fits the P50?
The top Picatinny rail accepts any standard red dot, holographic, or reflex sight that mounts to a Weaver/Picatinny base. Popular choices include the Holosun 510C, EOTech EXPS3, and Vortex Crossfire. No adapter plate needed.
Is the P50 reliable with all brands of 5.7x28mm ammo?
Per Kel-Tec specs, the P50 is designed to function with factory 5.7x28mm ammunition from major brands like FN, Federal, and Speer. It cycles best with 40-grain FMJ and 27-grain hollow points. Avoid underpowered reloads or steel-cased ammo for best reliability.
Can I use the P50 for home defense?
It can be, but the 5.7x28mm round is known for overpenetration through drywall compared to 9mm defensive loads. If you choose it, pair it with a suppressor (the threaded barrel accepts one) and use a high-quality hollow point like the FN SS197SR. The 50-round magazine gives you plenty of capacity, but the pistol is large and heavy for quick maneuvering indoors.
How do I clean and maintain the P50?
Standard field strip: remove the magazine, lock the slide back, rotate the takedown lever, and slide the barrel assembly forward. Clean the barrel and chamber with a 5.7mm brush and solvent, then lightly oil the slide rails and barrel hood. Avoid over-lubricating the polymer frame.
