During the opening flashback, several P229s are seen being pulled by the agents with the US Department of Damage Control who take over Toomes' (Michael Keaton) salvage operation. Later, Schultz (Bokeem Woodbine) is seen with a holstered one, while searching the Midtown School of Science and Technology for the gang's lost energy weapon, and a two-tone one is pulled by one of the thugs on the ferry. Toomes himself is seen taking one out of his car's glove compartment before giving Peter the "dad talk".
