Suppressors tend to increase chamber pressure so they usually help a pistol cycle harder but when you use subsonic ammunition, sometimes you’ll still run into issues. adding anything to a gun like a suppressor, obviously adds more points of failure. If the suppressor was homemade, it probably wouldn’t have a Nielsen device And would be more prone to jamming unless it was a single shot where the barrel doesent tilt when the gun cycles like a Ruger mark IV
