Cajun gunworks, cz custom, dawson precision all have good sights. The meprolights will work and are not that hard to switch out. If you can swing a hammer and hit a punch you can get the front sight out. The rear is going to need a vise to hold the slide and a good whack with a hammer to get moving. A good whack with a hammer and a brass or aluminum punch will get it moving. The new sights may need a litte sanding on the bottom to go in. Once the sights goes about halfway in without much force you can tap it the rest of the way in.
