So I have being permanently changing of guns to discover one that I like and in the process I have being trying to get the SMGs in diamond I’m 2 away of it (Chicom and Vector) which I HATE I don’t like those two guns at all. The best guns or the ones that I most enjoy are the PDW-57 ( as always) and the MSMC I have both in gold and the MP7 as well, which I also liked but the others are better.
The PDW-57 is the one that I prefer, it has a very low recoil and 50 clip size which allows you to spray much more and avoid the permanent need of reloading, you will also have 15 extra bullets with extended clip, it takes 3-6 bullets to kill (short and long distance) Unlocked in level 4. An amazing “720 fire rate (900 with rapid fire)” COD Wiki.
The MSMC is also an amazing gun it also has a low recoil, a 30 bullet mag (40 with extended clip) It also takes 3-6 bullets to kill but it may sometimes kill in less shots at long or short distances. Unlocked in level 28, with the same “720 fire rate (900 with rapid fire aswell)” COD Wiki.
The MP7 has a higher recoil but it is still almost nothing, it has a 40 bullet mag (54 bullets with extended clip) ) It also takes 3-6 shots to kill but has a lower body damage at short distance 4 bullets to kill when the others just need 3. The thing is that and 3 bullets if short distance headshot. Unlocked in level 4. An incredible “900 fire rate (1200 with rapid fire)” COD Wiki.
In general the MSMC is better than the rest but I still prefer the PDW-57 damage is higher in the MSMC but the PDW-57 has bigger mags so both them are almost the same (take in count ALMOST the same) I recommend all this three guns because of their damage and qualities but I personally would recommend the PDW.
