Closing thoughts

The MP5-SD is a silenced SMG that occupies the same loadout slot as the MP7; it's unique selling point is its silencer as the former deals more damage. Unfortunately this often is not enough to justify its high purchase price. However, a cheap (compared to a rifle) weapon that is silenced and has a high rate of fire can have utility in certain scenarios.

The MP9 is a stunningly effective weapon. On paper it is one of the strongest choices in the game, with a stellar rate of fire, speedy reload time and cheap cost. Oddly, it is also very accurate while jumping. A safe option for a Counter-Terrorist, it is almost never a bad purchase.
