Meh. You want sleight of hand if you're running about using these as a primary. You get plenty of ammo. Due to the bad range, lightweight is the best 2nd perk so you can rush your targets and get as close to them as possible before firing. Steady aim is a good perk as it makes the shotgun pellets have less spread and therefore greater accuracy, but ninja or scrambler could also be effective depending how you're using them.
Good tip. Most people don't think about this, smart.
thanks man, and true

Yes but due to the very small capacity, sleight of hand is pretty much essential for the fast reloading as you may use up all 4 shells on one target if it's a messy kill.
Also one more tip, the rangers have a very long reload animation, so as soon as the ammo appears in your HUD, sprint or YY. This isn't so important with SoH but still a good idea.
alright that point is true about the faster reloading, it can be life saving, but the thing you got to remember is, you are using this gun as a secondary, not your primary, so your primary gun is going to also change your decision on what perks and such you are going to use, so remember that
