Seriously dude. What gun could you POSSIBLY BE USING for you to ask tips about THE M9.
Well to be honest I find the AK easier to control/use than the M9, even without the accuracy mod.
Stick with the AK it has more Stopping Power than the M9, but its useless against an M9RoF, had a loadout with the M9RoF just in case, keep the default cam speed with fleet foot and adjust if ur not gonna fleet foot
you can always try the blindfire in maps with CQAreas, there i recomend the KAL+Micro n Weapons Expert or the Flynns M9 which has BF and its practicly = to the kal because it takes less bullets for a punch to work
, and remember the closer you are able to get to the enemy the better the BF gets
