Sight upgrade for Compact L

[parkgt]

I have a CZ 75B Compact L that is my favorite handgun of all time. The problem is my tired old eyes (70+) are no longer equal to what the gun is capable of.  This is not a normal carry weapon although I do have several holsters.  It is primarily a home defense and range gun that I enjoy shooting. 


So I am looking for thoughts on upgrading to either a milled slide and a red dot like one of the Holsun's, or laser since this gun has a rail or both.


Insights or experience with this scenario would be appreciated.

I have a Compact L and it is my EDC favorite.  The gun has been my constant companion since I purchased it from CZC.  Considering the rarity of your gun I would hesitate to modify it.  Instead of milling the slide for an optic I would take that money and purchase a new CZ which is optic ready.  The Shadow 2 Compact or full size Shadow 2 come to mind.
