As a southpaw my mk9k and gsl phoenix are the way to go. Even stuff like the old raptor 2 doesn't compare. I like my subgun cans on subguns and pistol cans on real pistols.I’m surprised so many people like pistol cans on their PCCs & SMGs. I don’t. Usually pistol cans are small diameter for sighting reasons, and as a result long, because they need more volume than the small diameter will allow. With PCCs & SMGs, the sights are much higher, so why not utilize a can with a much larger diameter? With the larger diameter, it can be made shorter and still have lots of volume. A long skinny pistol can is the last one I’d choose for the MP5 when there’s cans like the CT9KS, Phoenix, etc.
