How difficult is it to change sights on SIG 226

[Logs]

I have a Sig 226 and the Night Sights are worn out and hard to see. I was looking at putting a set of fixed sights on. I figured I would need a sight pusher, but is there one I can use for all makes and models or do I need a tool special to Sigs?
Thanks,

If you have a vice and some thing to give you padding you can tap the old ones out with a brass punch and ball peen hammer.

Really a universal changer like the P500 will cost about 100 bucks, and the hesco/meprolight univ pusher will be around 400. So it makes it worth it if you change out at least several sights. There are Sig sight pushers but wont help you if you want a universal sight pusher. Check Brownells.
