But if you read authentic accounts from the Old West, many called their revolvers "pistols." "He pulled out his pistol in the saloon, and began firing." Which is where the term "Pistoleer" came from.

Sorry about that. I forgot the best part -- the iconic line that has become a Western genre cliche.

From The Virginian: A Horseman of the Plains by Owen Wister (1902)

The Virginian's pistol came out, and his hand lay on the table, holding it unaimed. And with a voice as gentle as ever, the voice that sounded almost like a caress, but drawling a very little more than usual, so that there was almost a space between each word, he issued his orders to the man Trampas: “When you call me that, SMILE.” And he looked at Trampas across the table.

Good stuff. An actual real life quote said to the sheriff who captured him in 1877:

“I have killed twenty-seven men, and if I could have got my pistol out you would have made twenty-eight.” - John Wesley Hardin, Texas outlaw and premier pistoleer.

By the way the pistol he had on him was an 1860 Colt Army .44 cap and ball revolver.
