For the best performance, optimize the suppressor for the caliber. Doing a one size fits all results in substandard performance. a 1 decibel difference makes a big difference to the trained ear.
Good choice and congratulations to the HKUSP9 SD....You will be happy with it. I'm certain of that.
It will gove you 1970s era sound suppression. It will ne at or sligbtly above hearing safe bit nothing close to modern pistol caliber dedicated suppressor technogy.
Rifle caliber suppressors are more efficient using smaller projectiles throught them than pistol suppressors. It probably has to do with pressures and velocities and the larger internal vloume of large rifle suppressors. Where theres not much of a size difference in 45 cans compared to 9mm.
Great advice guys! I appreciate the info, and will abandon the idea of one size fits all when it comes to pistol suppressors. Thanks for talking some sense into me.
