I had a G24 slide hard chromed years ago and it looked great (but, damnit, has since been traded off). At the time (about 5 yrs. ago) it cost only $50 from Tripp Research in Alpine, Tx. but he no longer does this type of work. It is a simple operation and only requires you to send the slide to the customizer (the slide is not considered "a gun" so it can go USPS or any other method).
