I am, as I said, very happy with the Q-system, it’s my top slot weapon for general purpose (non-elemental) shooting, and because it scopes and handles so well I use it instead of snipers.
I looked forward to having similar luck with Atlas pistols. I didn’t.
I’m talking primarily about the AX series, I don’t recall if there are other Atlas pistols, none come to mind.
The AX’s are slow firing (which is OK in the Q, but not in a pistol), not heavy damage, and often are splash dependent which I don’t like.
For pistols in BL3 I use Jakobs or Vladoff. Jakobs becauses of the power and the crit- ricochet mechanic which kills many things, and of course Vladoff for raw fire rate. My current fav pistol is the Lucky 7, which as I mentioned elsewhere I’m going to do a complete play through using only that gun once I get my PS4 Siren through TVHM.
