20% heavier. Add ammo. 45 weighs more than 9mm. Maybe 25% heavier. When I hand my Thompson to someone the first thing I see is the shock of how much it weighs. Name a heavier subgun ?
The non acceptance of the .45 might be the answer to my question.
First of all, the Thompson was a successful military and police weapon and was well liked by the US and British troops that used it.
The Suomi KP31 was pretty much the exact same weight and was also a highly successful and well regarded weapon, the Finns would equip entire companies with them.
The Lanchester was around 9.5 lbs.
Is a one pound difference in gun weight really going to be a deal killer? It's not like all the other smgs were 4 lbs and the Thompson was 10 lbs. Most smgs were 8 to 10 lbs.
Even an UZI is almost 8 lbs and it's a tiny gun, a sub-compact.
The garand was spread around to our various allies, like the greeks, danes and the Italians. It's a 10+ lb gun and uses an American cartridge.\
To assume that a gun was not adopted by an ally because of ammo or weight is just spitballing, it's just speculation.
