I have a 2nd-generation G24, and I wish to install Heinie sights, which use a screw post for the front sight. None of my 3 front sight tools will fit into the access hole. Can anyone please advise me of a front sight tool that will work, or will I have to settle for using the factory sights for this pistol? I have installed sights on two of my G22s, and really prefer the "Straight 8" sight picture. Thanks!
