British detectives don’t really carry guns though. Unless they are part of a special unit. This Sherlock episode the post talks about takes place in modern day London so he would definitely not own a gun for his job. At least not legally.
Adding to this, in the first episode of Sherlock John Watson isn't even a detective/detectives assistant yet. He is a depressed, injured, former military doctor.

I guess it’s just a work of fiction then.
