Ever since the system's appearance, Luke had gotten more and more fond of guns.
Guns were weapons that he could openly use for the long term. With Tony Stark's abilities, it wasn't hard for him to make his own special weapons.
Gun modification was like an instinct that was in the playboy's blood.
Beginning with Howard Stark, who was Tony Stark's father and also a playboy, they invented a lot of weapons, including the iron suits ultimately developed by Tony Stark.
Although Tony Stark shut down the weapons division of his corporation, he never abandoned his pursuit of more powerful arms.
Though Luke wasn't as good as Tony Stark, it wasn't hard for him to make guns with Tony's abilities.
After he made two special pistols for himself, Luke fiddled around with other firearms.
While he could use a pistol as a police detective, it was impossible to take a rifle out with him when he was on duty every day.
