Actually, the Kimbers come with a dovetailed, rather than staked, front sight. I have heard that the Kimber rear sights are frightfully tight in their dovetail. Brownells offers McCormick (Kimber) sights with tritium inserts in a 3-dot pattern (www.brownells.com). Richard Heinie offers his SlantPro sights in a model to fit the Kimber cuts with the tritium dots in his "straight-eight" configuration. I believe that Heinie is offering quick turnaround on installing them (www.heinie.com).
