Infantrymen just carried the rifle, officers had the revolvers. A cavalryman would have carried the Krag Carbine and a Colt M1889, M1894 or M1896. The Rough Riders had Krag carbines and Colt SAAs. At Kettle Hill TR carried a Colt M1889 Navy salvaged from theMaine, not the Colt SAA he carries in the movie.
