I don't mind the shortness I just want the suppression to be close to the standard. Only reason I wanted a sd was they are so quiet... will have to look into more I guess, the pic above does looks to have the chamber....

It has to have an expansion chamber.
1. You guys realize there's a barrel in the gun, right? That barrel extends ~5" into the silencer. There's not going to be baffles in that area.
2. Blocking off the barrel ports would be stupid. It would cease to be an SD.
My only concern with this can is cleaning it. The only thing I can imagine is giving it a good bath in "the dip", but I don't know if that would get all the crap out of it or potentially let it settle and create a bore obstruction.
If it can't be cleaned, it doesn't make sense to me.
