I have an old, huge CAC9 Bowers can that was upgraded to the current baffle design used in the Vers9.
I use the barrel nut mount and have found that I get poor accuracy when using the can. Three shots will hit the bullseye, and the next three will be off the paper.
I don't see any bullet strikes on the baffles or anything. My Vector FA was re-welded and tuned by Richard Hoffman. The barrel is rock solid in the trunnion.
It was fine on my 9mm MAC10, but I don't know, something is amiss on the UZI. Maybe it's just one of those flukey ammo problems, maybe just barrel harmonics or some weird thing.
As far as sound goes, it sounds fine to me. People say this can or that can is quieter, but unless it's measured, who could really say? "To measure is to know." Name a can, and there is some guy somewhere who swears that it's the quietest.
Sometimes people will post up videos of suppressors, but it's pointless because both your cell phone microphone and your PC speakers "clip" loud sounds.
I will say that the machining quality on the bowers can and mount is excellent and the customer service is 100%. And the vers-adapt mount system is a great idea.
