The saber had a 1911 built into the hand guard with a sliding wire stock which made it a shoulder fired .45 ACP Carbine.
This design was notably designed by, at the time, calvery officer named Lt Patton better known today as 4 Star General George S. Patton. Arguably one of the most famous American military leaders to ever live.
Unsurprisingly, this experimental sabre never saw service. Possibly, it’s got to be one of the rarest US made sabres but as usual I look forward to the comments below where you tell me there is something even rarer.
I’m not sure the added weight is making it easier to hold it straight out.
It does, because the center of gravity isn’t hanging out on the end of a big lever. Have you ever handled a legitimately well made European style sword in real life?
They feel much lighter than you might expect.
Yes, I understand the center of gravity helps in general. But when you’re holding your arm straight out, as you would during a cavalry charge, the ultimate load point is still your hand, and at some point more weight is ultimately just more weight.
