Hiya buddy10mm and thx for the thread. Have ya considered trying nitesighters they cost 12bucks and could work for your need. Having thought I needed trijcons on a cheap 600buck p-02, would have been worth the 230install cost if they improved sighing, made daytime practice more difficult having the pale white front blade. So then add the cost of going back to the factory sights and coulda bought a new witness p for the cost of that failed experiment. If ya got money to burn go for it, but I come from being fixed income and would consider drilling my factory sights for FO rods before spending hundreds on night sights. Be well.
