how a silencer works (Silenced HK USP 9SD)

RATE & COMMENT please! How a silencer works: A silencer is just an can with several baffles(although the B+T Impulse IIA has a built-in recoil enhancer to ensure reliable functioning for browning action pistols). The baffles are there to progressively slow down and deflect the expanding gases. So that when it reaches the end of the silencer its no longer a single shock wave, but a low-pressure flow. The gun is a HK USP 9SD date code AI. It has match trigger with trigger job.
