I'm looking for a gun which isn't elemental ( My arsenal is crammed with elemental weapons ) so, anyone has a suggestion?
A Good Gun
Umbra Driver or Sentenza (or Biohazard, but probably not) for shadow damage.
Blitz Needle or Callahan (or Plague Needle, but probably not) for piercing damage.
It depends on the damage type you want.
To be honest it's best to have an elemental gun and a peircing sword due to the fact that the things you would want to do peircing damage to, move around on gun shots, wolvers and devilites, and the things you want to do elemental damage to usually have some ranged attack (all turrets, and some undead.)
Though normal is great to because it is the same damage for everything.
Try our vialance or even neuturalizer for normal damage.
Blitz Needle. Because it is so absurdly powerful I use it for most everything not resistant to pierce. It is also almost required for FSC.
After that an Umbra Driver. Or, if you don't like alchemers, a Sentenza.
If you get a Valiance, you will likely eventually stop using it for PVE. It's a really solid sidearm for PVP, however, so it wouldn't necessarily be a bad purchase.
Pepperbox. S'basically a blitz that works on everything and starts fires for you.
Valiance is amazing... for both PvE and PvP.
Pepperbox is also amazing, like Darkbrady said... it is more complicated and different than the blitz, although it is disappointingly balanced rather than being overpowered.
Almost all of the guns are fun though, so its not like you can really go wrong. Unless you make a calahan/iron slug. Those are just awful.
Iron Slug. It's stylish, fire big bullets of doom, and the charge has an even more bigger bullet of death!
Else, you could try to be a little more precise than "not elemental". And search a little on the forum. And on the wiki. Oh, and read the Gunslinger guide. Actually you should START by that.
If you have specific questions after that, well, ask specific questions. Else, go with Neutralizer, it's great too! A weapon with that name can't possibly be bad!
