You’ve seen the movie scene a thousand times. A sharp-dressed man in a pinstripe suit and a fedora strolls down a rainy Chicago street. He’s clutching a weathered leather violin case. He looks like a musician on his way to a rehearsal at a jazz club. But then, the screech of tires, a black sedan pulls up, and suddenly the case is open. Instead of a Stradivarius, he’s pulling out a .45 caliber Thompson submachine gun with a 50-round drum magazine.
It’s the ultimate icon of the Prohibition era. But honestly? The tommy gun violin case is more of a Hollywood fever dream than a daily reality for 1920s mobsters.

Don't get me wrong. It happened. But it wasn't the "standard issue" gear that movies like The Untouchables or Public Enemies would have you believe. Most real-life hitmen were way more boring with their logistics. If you were a "button man" for Al Capone, you were probably more likely to wrap your "Chicago Typewriter" in a greasy newspaper or shove it into a standard suitcase.
Why? Because a violin case is actually a huge pain in the neck for a weapon that weighs almost 12 pounds.
The Problem With the Myth
Basically, the physics don't really work out for a quick-draw situation. A standard 1921 or 1928 Thompson submachine gun is roughly 33 inches long. A standard violin is about 23 inches. You do the math. To fit a Thompson into a real violin case, you have to take the thing apart.
You’ve got to pop off the buttstock. You’ve got to remove the drum magazine. Sometimes you even have to unscrew the barrel if the case is particularly small.
Imagine you’re in a turf war with the North Side Gang. You see your target. You don't have three minutes to sit on the sidewalk and assemble your firearm like a LEGO set. Most gangsters preferred the "trench broom" to be ready to sweep the moment they saw a rival's car.
What really happened
Historical records from the FBI and Chicago police show that while "specially-constructed cases" existed, they were rare. Most of the "guns in violin cases" stories come from the 1930s movie era. Hollywood needed a visual shorthand for "sneaky criminal," and the juxtaposition of high-culture music and low-culture violence was too good to pass up.
There is one notable exception, though. A mobster named "Buster from Chicago"—a hitman for the Genovese family—was known for carrying a sawed-off shotgun in a guitar case. But a guitar case is massive. You could fit a small armory in one of those.

Why the Tommy Gun Violin Case Still Matters
Even if it was 90% myth, the tommy gun violin case became a cultural juggernaut. It represents the "Robin Hood" glamour that the public projected onto criminals during the Great Depression. In 1931, the academic journal American Speech actually defined the phrase "violin case" as gangster slang for a machine gun carrier.
So, while the hitmen weren't always using them, the people were definitely talking about them.
Real Examples and Survivors
If you go to the Mob Museum in Las Vegas or look through high-end auction catalogs like Rock Island Auction Company, you will occasionally find vintage violin cases that have been "gutted" and fitted with velvet-lined foam or wood blocks to hold a Thompson.
- The MGC Replicas: In the 1970s and 90s, Japanese companies like the Model Gun Corporation (MGC) sold sets that specifically included a non-firing Thompson replica inside a violin case. Many of the "historical" photos you see online today are actually just people posing with these toys.
- Police Training: There are a few documented instances of police officers using confiscated cases to demonstrate how easy it was for criminals to hide "heat" in plain sight. It was a great PR move for the police to show why they needed more funding and better gear.
The Hardware Specs
If you were going to try this today—legally, with a registered semi-auto or a prop—you’d realize how heavy it is. A loaded Thompson with a 50-round drum weighs about as much as three or four actual violins.
- The Gun: 10.8 lbs (empty)
- The Drum: 4.5 lbs (loaded)
- The Case: 3-5 lbs
You’re walking around with nearly 20 pounds of metal and wood in a case designed for a 1-pound instrument. The handles on vintage violin cases are notorious for snapping off. Honestly, if you saw a "musician" in 1924 struggling to carry a tiny case that seemed to weigh as much as a bowling ball, you’d probably get suspicious pretty fast.
Actionable Steps for Collectors
If you're looking to recreate this iconic look for a display or a film project, don't just buy the first case you see on eBay. You'll end up frustrated.
- Look for a Viola Case: A viola is larger than a violin. The extra few inches make fitting the receiver and the barrel much easier without having to do a full teardown.
- Reinforce the Handle: Most old cases use thin leather straps. If you put a real Thompson (or even a heavy zinc replica) in there, that handle is going to fail. Screw a metal plate into the frame under the handle.
- Custom Padding: Don't use modern egg-crate foam. It looks tacky. Use high-density upholstery foam and cover it with deep red or purple velvet. This gives it that "authentic" 1920s luxury feel that the movies sold us.
- The "L" Drum Issue: The 50-round drum is the iconic look, but it's thick. Most violin cases aren't deep enough to close over a drum magazine. You usually have to store the drum separately in the "accessory" pocket of the case or use the 20-round stick magazines.
The tommy gun violin case is a perfect example of how we prefer a cool story over a boring truth. Gangsters usually just threw their guns in the trunk of a Cadillac and covered them with a blanket. But "Gun Under a Blanket" doesn't make for a very good movie poster.
The myth is what stays. It’s the symbol of an era where the rules were broken, the music was loud, and the "fiddler" might just be a professional killer.
If you're hunting for one of these for a collection, focus on the 1920s "H6" style cases. They have the right depth. Just remember: it’s a display piece. If you actually try to carry it to the range, your back—and the handle—will regret it within ten minutes.
