Front/Rear Sight Advice?

I just bought a Springfield PX9154LP last night. It has the standard 3 dot non night sight. I believe it is a Novak low/dovetail design/mount. Anyways, I'm looking to get a better target sight. I've always liked the flat blade design with white outline. I don't know which brands are recommended and which ones will work well without machining the gun.
The front sight Im leaning towards, at least right now, would be a fiber optic.
Note: I don't like night sights or 3 dot sights.
Recommendations or suggestions anyone?
