Hello everyone. I own one gun. It is a Ruger SR9c, and i love it. The stock sights are fine but I would like more contrast and brighter sights. The stock white dot on the front sight burnt off while shooting 100 rounds through the gun at the range. Paint also burns off. I would like to upgrade, but not sure what is right for me. Can you folks explain the pros and cons of fiber optic and tritium? Can you help me understand if my handgun is a DIY sight replacement job or will I need a gunsmith? The purpose for this gun is a jack of all trades. It is my concealed EDC gun, home defense, and range gun. Thank you for the help.
