I found the dueling pistols
The Pistols
Others have attributed Hamilton's apparent misfire to the hair-triggered design of one of the Wogdon dueling pistols, both of which survive today. One of the pistols has a flint-lock firing mechanism and the other has been converted from the original flint to a percussion firing mechanism. When asked by Pendleton before the duel if he would have the "hair-spring" pistol, Hamilton reportedly replied "not this time."[23]
The pistols belonged to Hamilton's brother-in-law, John Barker Church, who was a business partner of both Hamilton and Burr. He purchased the pistols in London in 1797. They had previously been used in a 1799 duel between Church and Burr, in which neither man was injured. In 1801, Hamilton's son, Philip, used them in a duel in which he died. In 1930 the pistols were sold to the Chase Manhattan Bank, now preserved by JPMorgan Chase & Co.
