I haven't seen tracers in nearly 20 years, I used to get the bullets in 9mm, .38 and .45, but I don't know where to get them anymore. I especially liked the .45's, I'd load them very light (about 700 fps) and watch them streak to the target. Great around twilight, you can really see the arc of the bullets path. I recovered a few from the sand hill and there was nothing left but the hollow copper jacket. I gave a few handloaded .38's to a PO friend who went night shooting at the police range, he said it was a real hoot. The range officer asked what he was shooting for loads but he just acted dumb and said "some reloads I got at the police supply store". The range officer then told him not to bring that stuff anymore.
