Although anachronistic, Spicer Lovejoy (David Warner) carries an ornate nickel-plated M1911 (even though a non-nickel M1911 would have been more correct for someone to carry in 1912, as the weapon hadn't achieved widespread usage yet). At one point, Cal Hockley (Billy Zane) grabs the M1911 from Lovejoy's shoulder holster and chases Jack (Leonardo DiCaprio) and Rose (Kate Winslet) through the sinking ship. The 1911 came from Stembridge Gun Rentals. It was chosen because the patent date made it plausible. The Colt 1911 started to be issued in test articles around early 1912 to the US Military. Notice the 1911 has a 1911A1 hammer on it.
Webley Mk I
The officers of the Titanic can be seen with Webley Mk I revolvers, just as the real officers had carried. First Officer William Murdoch (Ewan Stewart) uses his to shoot two passengers before shooting himself. Second Officer Charles Lightoller (Jonathan Phillips) can be seen threatening several passengers with his, just before actually loading it. Fifth Officer Lowe (Ioan Gruffudd) also briefly can be seen with one, even though the real Officer Lowe carried his own sidearm on the ship, an FN Model 1900.
Remington New Line No.1
A crewman guarding the third class passengers at a gate below decks during the sinking draws a Remington New Line No.1 and aims it at them to keep them away from the gate.
