|CZ Scorpian Evo 3|
These are semi-auto versions of the Evo 3 submachine gun. They are 9 mm, closed-bolt (of course), with rails and threaded barrel. And relatively inexpensive for both the gun and the magazines. More information at The Firearms Blog, which indicates that it will come with a SIG brace.
IWI is also going to be releasing its UZI Pro Pistol with an SB tactical brace next year.
