[the elite merc]

Since I don’t want to start off a new thread. I’ll just put It here.
Currently I’m trying to get the golden Executioner, after that it’s the kap-40 and I will have all secondary’s gold (diamond).
But does anyone has some tips for getting headshots with it? I mean, I am fairly good player with pistols (been playing mostly with pistols since cod 4) but this gun feels so off to me. I don’t like the full auto or burst pistol that much either (semi auto is the best) but I have been playing hardcore kill confirmed, I got 9 headshots I think, in like 5-8 games, which is not much off course because of the randomness of this gun, sometimes I need to headshot someone standing still twice, and sometimes I feel like I’m across the map and I get a headshot. But does anyone has some tips how to effectively get headshots and play with this weapon.
