That's a popular gun; but with very limited range. That cartridge is a short-ranged affair, as it was meant to be. But at longer ranges the gunner can make it rain .45 slugs.
The film is interesting, professionally made and enjoyable to watch. Thank you. Of course, the US Marines used the Thompson gun long before the US Navy became involved. The correct title should be: Thompson Submachine Gun, U.S. Navy Model. Auto-Ordnance Corporation did not advertise for sale a "Colt Navy Thompson." This phrase is simply collector speak. And John T. Thompson did not design the Thompson Submachine Gun. General Thompson was the developer; he assembled a small team of engineers and formed the Auto-Ordnance Corporation. The result of these efforts was the production in 1921 of a submachine gun named after General Thompson.
