My observation was it seemed that 9mm wet was almost a waste. It seemed like you had a big mess to cleanup after shooting without much gain in suppression. The tirant 45 dry had a higher pitch(sound won't carry far) and the osprey 45 dry had a lower pitch so the osprey seemed louder until the 3rd shot and then my ears seemed to like the tone more.
Wet the 45 osprey was rediculous on that 1911. I had never heard it in an open environment like that as I had only shot it wet in my backyard where I have too many sound reflecting surfaces. The 1911 with osprey45 wet was incredible!
