Police in Calgary have arrested two men suspected of running a firearms production and trafficking operation.
Calgary officers have seized more than 12-hundred firearms _ including more than 300 believed to have been used in a crime _ so far this year.
Nine per cent of those guns were homemade or 3-D printed, which police say is a significant increase over last year.
Acting Staff Sgt. Ben Lawson says the 3-D guns are a growing trend and function the same as regular firearms.
Brandon Vincent-Wagner, 24, and Justin Kumar, 27, were arrested on Aug. 16 and charged. Vincent-Wagner is scheduled to appear in court on Sept. 30. Justin Kumar is slated to appear in court on Sept. 28.
