Cylinder & Slide says they can get the trigger down to a crisp 5 lbs, without removing the mag safety (they won't remove it, for liability reasons).
Novak's shop also used to customize them, however I don't see a website for Novak's any more.
I have two of them, one a MkIII and then Dad's Belgian Browning. I've always liked them as a slim & ergonomic pistol, well balanced for the cartridge, and much handier than most of the Hi-cap 9mm's. If you prefer a single action auto, but want more capacity, the BHP is still valid.
