OK - proud new owner of a Kimber Custom II with fixed sights from the factory. Not completely committed to changing them yet, but wanted some feedback on who makes a good fiber optic rear adjustable sight for these. I have read enough to know that I will be sending the slide off to have this done by a 'smith, but not sure who makes a good sight. I have a set of Williams Firesights on my Buckmark, and I really like them. They don't list an adjustable rear sight at all on their website. Novak has adjustable rears in black, white dot or nite sights, but no fiber optic. Any opinions out there? I want the flexibility of an adjustable sight for shooting different loads.
