Where is the Brass?

[nikvoodoo]

I'm going to lean in the direction that the shooter policed up the brass... that said you can suppress some revolvers such as the 1895 Nagant (Devils advocate: Burt could have had one and might be the special weapon). The crack that you hear in the gunshot is also when the bullet itself breaks the sound barrier, that's why if you are using a suppressed weapon you need to use subsonic rounds or you'll still get a pretty loud "crack".

I read that too in my research against the revolver, but I wasn't as clear about the mechanics and certainly wouldn't be capable of defending the point against anyone that could bring up a question about it.
