Rex Firearms has expanded its existing line of high-quality pistols by introducing the REX Zero 1 Tactical Compact. The standard REX Zero 1 Tactical pistol has been a favorite amongst consumers due to its renowned reliability and the fact that it comes from the factory ROR (Rex Optics Ready).

By combining all of the benefits of the REX Zero 1 Tactical in a smaller, compact package, Rex Firearms have once again hit the mark.
