Since we are talking Kimber here, let me use my pistols for examples. I have both a Classic Stainless (fixed) and a Stainless Target (adjustable). The CS will hit POA with factory ball ammo at 25 yds. Ths CST will hit anywhere I want it to. I use the CST in competition. I reload my own ammo and I am still tuning different combinations between bullit weight, 200 vs 230, and velocities. I have changed the front sight on this pistol. Having the ability to adjust the rear sight lets me change things and resight the pistol to where I like it, dead on at 25 yds. I know some who sight theirs in at 15 yds, others at longer distances.
For everyday carry, I like fixed sights. More rugid, and have a no snag profile. Heinie SlantPros are the way to go. For competition, I like adjustable.

The next Limited or IDPA gun I build will have Heinie slant pros. I fact, all my IDPA guns have Heinie sights. Pick a load, sight it in, and never look back. Speed first, accuracy will come... or so I am told.
