ABSTRACT:
A compensator having an enlarged chamber is threaded onto the barrel of a handgun. The compensator has two equally sized, symmetrically positioned vertical upper ports aligned with matching ports in the threaded portion of the barrel, for vertically exhausting high pressure gas to produce a downward force that resists muzzle climb. The chamber also includes a pair of unequally sized, unsymmetrically positioned low pressure ports through which lower pressure gases are exhausted as the bullet leaves the chamber, compensating for rotation produced by the torque produced on the bullet by rifling of the barrel bore as the bullet accelerates.
