We have listened to our customers and this new run has the requested features. We have enlarged the wrench flats for a more positive engagement as well as reduced the overall length of the 1/2 x 28 threads so there is no worry of hitting the internal baffles of the suppressor with the threads.

Exceptional quality replacement barrel for the Cobray/SWD M11/380 & M12/380 series of submachineguns & semi-automatic pistols.

Our custom 380 barrels have the larger 9mm 3/4" threads for installing an old-school 9mm SIONICS suppressor, or for installing our Pat-Pend 9mm MacAdapter, as well as having 1/2"-28 threads on the muzzle for installing a modern 9mm suppressor or AR15 type 9mm flash-hider/compensator.
