 One more advantage....on the Ballistic Benefit barrel is the fact It really is The federal government contour rather than the large.  A con naturally is usually that it's nitrited instead of chrome lined, but for the kind of taking pictures I might be performing, and on a 9X19, it would get the job done just as properly (and I could market my 2nd 16" Colt 9mm barrel and not come to feel terrible about chopping it).

Functions great in all my Pistol Caliber Carbines, under no circumstances a problem with feeding. I know some PCC's can have a problem with hollow factors, so when you go that route for defensive ammo make certain the ammo you choose will cycle properly.
