I bought colt from a deputy Sheriff in 1957. I know from the ss# it was made in the 1920s. I am careful not to shoot +p in it. As you can see it has not been shot a lot but I have carried it for many many miles. Well before carry in Texas it rode close but out of sight. I have used two loads in the pistol. 158gr cast lead hp at around 750fps and 148 gr hollow based wade cutter loaded backward (used to be very popular in the 60's) at about 800 fps. It is kinda funny today but I never felt under gunned with what I taught the threat would be. When I carry it today I still don't feel under gunned. Today I got carry pistols that double the energy easily of the colt. They don't carry as well as the colt. Colt carries very well with iwb holster and is very quick to draw and shoot.
