“The De Lisle carbine or De Lisle Commando carbine was a British Carbine used during World War 2. The primary feature of the De Lisle was its very effective suppressor. That, combined with its use of subsonic bullets, made it extremely quiet in action, possibly one of the quietest firearms ever made.
Few were made as their use was limited to special military units.”
This is the De Lisle Commando Carbine - not well known but still played its part in military history. It was in service from 1943 to 1965 and it used .45 calibre ammunition. The british commandos used it in WW2 for one primary reason - the De Lisle Carbine was extremely quiet, making it useful for stealth missions at the time. It is often recalled as one of the quietest guns ever made.
The De Lisle Carbine is a .45 caliber rifle with a built-in suppressor. It is extremely rare, with only a few hundred being built, although a few manufacturers make modern replicas. It’s crazy how quiet this gun is. I’ve heard suppressed .22s louder than it. It’s too bad that legal obstacles prevent this rifle from being more widely produced. It would make a great home defense weapon, as it has no blinding flash or deafening blast.
