I have used a number of different handgun powders over the years, loading .38 Spec., 357 Mag., 9 mm, .44 Mag., .45 ACP, and .40 S&W. Unique, Universal Clays, Accurate No. 5, SR-4756, and Win. 231/HP-38 have all been considered as my "all around" choice for handgun loading. I have also used a lot of Titegroup lately for 9mm and light loads in .357 revolvers. With the scarcity of handgun powders in recent years, one had to grab what one could find, and a while back the local Sportsman's Warehouse had a 4 lb keg of Power Pistol. I think this is my new general purpose powder. I have used it in .45 ACP and 9mm, and just today chronographed some 357 Mag. loads with some 170 gr Keith style cast SWC's with very impressive results. It seems to provide excellent high level performance. I haven't tried any light loads with it yet, but with upper level loads, it is very consistent.
