I'm looking to run a pure wizard but i'm out of ideas for weapon prof...magic implements are the better choice? or weapon + shield for defense? also, i really like the idea of a gun wizard, shooting people when i run out of spells. is it viable? which is the most efficient? 

thanks in advance

I would also like to know. What did you end up going with? Anyone else have input?

Any weapon is viable so far, I prefer magic missile! Or any weapon that has dual damage type.

i took pistols and quarterstaff, i'm playing on POTD (pure wizard). I'm early on the game but its ok so far, game is not hard,
