What is philidelphia derringer?

The Philadelphia Derringer is a small, single-shot pocket pistol developed by Henry Deringer in the mid-1800s. It was popular among gamblers, saloon keepers, and other people who needed a small, concealable firearm for personal protection.

The Philadelphia Derringer was only about six inches long and had a .41 caliber smoothbore barrel. It was generally made of brass, although some models had iron frames. The pistol was loaded by unscrewing the barrel and dropping a single lead ball and powder charge into the chamber. It had a simple trigger mechanism and was fired by pulling back a hammer and squeezing the trigger.

The pistol gained notoriety after it was used to assassinate Abraham Lincoln in 1865. John Wilkes Booth used a Deringer pistol, which he purchased from a Washington, D.C. dealer, to shoot the President at Ford's Theatre.

Today, the Philadelphia Derringer is no longer in production, but it remains a prized collector's item and is often replicated in modern firearms design.
