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.
