A hand pistol and a revolver with four rounds of ammunition were part of a haul of weapons seized by police during a week of action on gun crime.
Officers made 17 arrests and seized six firearms between November 21 and 27 using targeted patrols in parts of the capital most impacted by gun violence.
They also carried out 14 weapon sweeps in partnership with community members.
Det Supt Tim Mustoe said: "We have been relentless in identifying, arresting and charging criminals who use firearms to target rivals and run criminal enterprises.
“We can reduce gun crime far quicker if members of the public provide us with information about those responsible, where firearms are being stored and who they are being used by."
Officers seized items including a live 2.2 Berringer hand pistol, a live .38 Rimfire Calibre revolver with four rounds of ammunition, four suspected blank firearms and a stun gun.
Class A and class B drugs including imported skunk cannabis with an estimated value of £20,000, was also seized.
Of the 17 people arrested, 12 were charged, recalled to prison or have appeared in court.
Two men, one aged in his 20s and the other in his 50s, were charged with conspiracy to murder and possession of a firearm with intent to endanger life.
The charges relate to a series of four shootings in west London.
Both men have been remanded in custody, police said.
Throughout the week, officers visited schools and local groups to engage with young people on the dangers of carrying firearms.
Det Supt Mustoe added: "Tackling violence is a priority for the Met and our response to gun crime is strong.
"We have deployed extra officers in the small pockets of London where we’ve seen shootings take place.
"Officers are developing fast time intelligence and executing warrants to arrest those involved in gun crime.
"The majority of shootings in London are linked to street gangs and organised crime groups so the likelihood of being a victim of gun crime, if you are not connected to these groups, is low.
“However, we recognise that gun crime can have a devastating impact on victims and their families.
"If you do not want to report this information to the police, you can contact the independent charity, Crimestoppers, 100 per cent anonymously. You could save a life."
