Actually the UZI’s are made for right handed people, you will note where the thumb safety is located.

One thing to consider, the arm brace just got a nastygram written about it, from ATF.
Don’t think this is a way to shortcut the SBR process.

The fired cases eject to the right and up, the worst that may happen is they bounce off the brace when its folded.

Personally, I’d rather have a re-release of the older Pistol, Mini-Uzi Carbine and such.
