Pistol nut gets 3yrs.
Darren Lake, 34, was caught with a blank-firing 9mm handgun and a butterfly knife at Humberside Airport after holidaying in Lanzarote with his mum.
Experts said the pistol could have been converted for live rounds. More guns and a samurai sword were found at his home.
Judge John Dowse, at Grimsby crown court, told Lake, of Rotherham, South Yorks: "I cannot turn away from the seriousness of these offences."
