Adventure when to get a new pistol after DoW

Hi there~

My pistol Advy is just about 13x now using JEPP + DoW works totaly fine in ely!

My question is, when should i update my DoW and for what should i do so ?
Is the special edition Kyr pistol even better then DoW ?
Think i am still far away from the MBS of DoW^^

Thanks in advnce

I guess theres no upgrade until u can get the upgraded Beast Pistol on and later on the Twitch Pistol.
So u gonna use the DoW for 70+ more Levels.
