I need a little advise,

I like the Glock's rear sights on my G22c but it's hard for my eyes to get a fast target acquisition with the stock white dot front sight. I need a more thin and bright front sight that contrasts with the white on the rear.

Is it possible to just swap out the front sight with a Warren Tactical fiber optic front and be able to keep the same configurations as far as aiming?

Sure it's possible...

Here's the "sight"... http://warrentactical.com/index.htm

You definitely can, but you have to be sure and get the correct height. I swapped mine for a Dawson Precision fiber front and a Heinie rear. I'd contact Warren Tac. to verify the proper height to match the rear.
