Precision's will be narrower than 19mm, probably 18mm. I tried that and just couldn't stand it. I was hitting two strings at a time, but 19mm is just right.
Most Lakland 5's have normal spacing (19mm), such as a 5501 or 5502. Also a Brubaker Brute, Carvin Bunny Brunel, or Carvin SB5000 all will have normal 19mm spacing.
