Have a G23 Gen 4 and am having issues seeing the front post sight. This gun is not for conceal carry. I don't have $300 plus for C-More STS sights. So I'm thinking of the TruGlo Tritium/Fiber Optic sights. For $100 not installed it seems like a very good all around sight. I do not have the tools required for the job so I need them installed. Q1. Am I missing anything on this pro or con of the TruGlo Trit/FOS sights? Q2. From a gun smith, what is the range of money I should expect to pay for proper install and alignment? Q3. Any thoughts on rear sights being green or amber vs all been green? Thank you all for your idea's.
