Q & A
What magazines does it use?
The KP50 uses two standard KelTec P50 25-round magazines inserted side-by-side in the grip. These are the same magazines used in the P50 carbine.
Is it compatible with FN Five-seveN magazines?
No. The KP50 is designed specifically for KelTec’s proprietary P50 magazine system and is not compatible with FN Five-seveN or other 5.7x28mm pistol magazines.
What is the trigger pull like?
The KP50 features a single-action trigger with a consistent, crisp break. It’s designed for precision shooting and is one of the standout ergonomic features of the pistol.

Been in the market for a while and finally decided to buy from Phoenix Firearms & Accessories. I was comparing this against similar products from the other site and decided to take the chance. Glad I did. Arrived in 5 days, well-packaged, and the quality speaks for itself. Installed it on my G23 and ran 115 rounds through it without a single hiccup. This is the real deal.

I’ve been shooting for 6 years and I’m picky about where I buy accessories online. Phoenix Firearms & Accessories earned my business. The KelTec KP50 5.7x28mm Pistol arrived in 3 days, packaged well, and fit my Glock 43X without any modification. I put 195 rounds through it that same weekend and had zero issues. The finish quality is better than I expected at this price point. I’ll be back for more.
