I have a .32 Colt Police Positive Revolver, that I inherited from my father, manufactured in 1911 (the gun, not my father). There is an amazing amount of clutter on the internet concerning the appropriate ammunition for this pistol. My understanding, from all of this clutter, is that Colt chambered this gun for a S&W .32 Long, but not wishing to give S&W any unnecessary advertising, produced the same cartridge as a "Colt .32 Police Positive", which is now out of production, as is a Colt .32 Long. I trust fellow monkeys over stray internet "experts." Does anyone KNOW, not think, what the appropriate ammo is for this pistol? The pistol is in very good shape, and appears functional in every way, but it hasn't been fired, to my knowledge, in decades. It currently is loaded with some very very old .32 Colt Short rounds, which are probably as much antiques as is the pistol. Any assistance would be appreciated.
