[1][2] The Bruni Olympic 38 is a double- and single-action blank-only revolver that is chambered for the .380/9mm R.K. (Rimmed Knall) blank cartridge and is fed by a 5-round swing-out cylinder.
[4] The Olympic is primarily available in black and nickel finishes with wood grips,[5] while variants exported to the United Kingdom are manufactured with bright orange or blue frames for buyers without a valid legal defence in purchasing a "Realistic Imitation Firearm" as per the UK's Violent Crime Reduction Act of 2006.
[6][7] Bruni manufactures front- and side/top-venting versions of the Olympic 38 with the latter for countries (such as the United Kingdom) with more restrictive laws on blank-firing gun replicas.
[8] The Bruni Olympic 38 was banned in the United Kingdom on June 4, 2010 following 179 police seizures of lethally-modified revolvers by criminals with some examples having been used in attempted murders.
[11] A newer variant of the Olympic is currently sold legally in the United Kingdom with revisions to its design, such as the cylinder to prevent conversions into a lethal firearm.
