Can you recommend a gunsmith in the Louisville (ST. Matthews hopefully) area that can replace the magazine release button on a CZ 75 Kadet pistol? I have the replacement release button and have broken 2 screwdrivers the screw that holds it in. The screw is still perfect, just the screwdrivers failed. The outer part of the screw is serrated like maybe there is a specialized thin-walled socket that fits over it. I live in Ashland, KY but I get down to Louisville frequently.
