KelTec P50 For Sale
The KelTec P50 for sale at Star Gun Shop is a distinctive 5.7x28mm semi-automatic pistol built around a high-capacity magazine design. Unlike a standard compact handgun, the P50 uses a longer 9.6-inch threaded barrel, polymer frame and top-mounted magazine layout that gives it a unique profile in the KelTec lineup.
This product page replaces incorrect copy that listed the P50 as a 9mm or .45 ACP pistol. The KelTec P50 is chambered in 5.7x28mm, and buyers should only use ammunition that matches the firearm’s marked caliber.
