Texas star, are you sure of the police positive not being available in .38 special? I have had several hundred old classic guns come and go, and I am pretty sure I once had a police positive in .38 special. I remember it being like new with colt emblem ivory grips. I could be wrong and maybe it was .32 wcf, but I dont think so. Even if it was .38 special, I would only use standard loads.
