WW2…The French Resistance. To help it out, America made and dropped a lot of these simple, lethal, and surprisingly accurate (over short ranges) weapons to aid the Resistance in acquiring better arms and equipment.
What isn’t widely known is that some, like one acquired by my grandmother (who was sent by British Intelligence to France to aid and build up the resistance) that she had modified in a basement workshop for a ‘muffler’…not a full-out silencer, but it did aid in close-range stealth-kills and eliminated muzzle flash. That particular weapon accounted for 8 Nazis rendered ‘Unfit for Service’.
Now, consider what can be done with modern materials and tools in small or basement workshops. Concerned about power usage giving you away? Look into the Blackwinter Power System under ‘Logistics’ here on this blog.
