Sight adjustment how-to?

For those of us who have only attended the Wylie E. Coyote School of Gun Tinkering (online version) …

Anyone reference a good article or thread on the proper way to adjust pistol sights (front and rear)?

I recently replaced a set of stock front sights on my M&P with Tritiums, but I’m a little off. I’m happy with just tinkering a bit with the windage but was wondering if there was more to it.

Thanks!
