One of the greatest challenges facing the suppressor designer today is developing a successful can for the .45 caliber pistols. That challenge is a triple whammy. It’s very hard to delay and cool combustion gases with such a big hole running down the central axis of the suppressor. It’s hard to achieve enough sound suppression in a large-bore suppressor without excessive length, diameter, and weight. And it’s hard to pack enough performance into a .45 caliber can without adversely affecting the reliability and service life of the pistol.
We compared three popular .45 sound suppressors to see how effective they are at providing solutions to these challenges: the USP from Knight’s Armament, the Evolution 45 from Advanced Armament, and the Impuls IIA from Capitol City Firearms. Let’s begin by comparing the designs of these three cans.
