Gun enthusiast Calvin Martin.

The inventory of guns stolen from a downtown Toronto collector is staggering and frightening: 50 handguns, two shotguns and an Uzi.

It’s assumed they’re now on the streets, being moved briskly in the city’s underground market.

The firearms were stolen from the fourth-floor apartment of lawyer Calvin Martin, a gun collector who amassed more than 200 firearms and stored them at home.

Toronto Police said Martin is now in a convalescence home and sources say it’s not expected that he’ll return to his Isabella St. home near Church St.

Police were called to the home last Sunday night after it was discovered that a burglar or burglars broke into the apartment and got into a storage area inside the apartment.

Along with the cache of weapons, a large-screen television was pilfered.

Sources said video surveillance is being studied by detectives for leads on the identities of the thief or thieves.

But police also say area residents would have heard the attempts into breaching the storage area, and it’s likely someone would have seen the burglar or burglars moving their loot through the building.

Martin describes himself on his website as being a target shooter and hunter since he was about 10 years old. He also provides a long list of club memberships and firearms training credentials on his resume.

An intriguing part of his resume is that he says he developed a practical pistol course for the Guatemalan Army and a practical shotgun course for Guatemalan Special Forces.

Police have said his collection was properly stored and licensed.
