Introducing the New AirForce Texan LSS. With its 34″ barrel, it can hurl .45-caliber ammo as fast as 1,000 FPS at muzzle energies of up to 600 foot-pounds, AirForce reports. And, it can do it much quieter than its older, unmoderated sibling. Before this, AirForce Airguns shooters desiring the same big-bore bite as the Texan with significantly less bark often looked to the Texan SS and its Sound-Loc System technology. But, that option comes with lower velocities and muzzle energies that go along with an almost 10-inch shorter barrel.
