RS 1911 parts
 

Can real steel parts from a 1911 fit on Tokyo Marui 1911s (MEUs and 1911 alike)? If so, which parts would be compatible?

The grips.

I saw a guy here who has good trader feedback selling RS parts for a 1911. What's the purpose of that?

And the Real Sword isn't an AK 47. Its a Type 56 produced for the Chinese military which, granted, is an AK clone.

Also for real steel 1911 parts, there are a bunch of accessories like sights, barrel bushings, and other superficial parts. Little if any internal parts will work.

I dunno about compatibility with the TM 1911 specifically, but I know some real steel 1911 parts did fit other brands (WA and WE). Barrel bushing (with minor fitting), recoil spring guide, grip, a few other parts look like they might fit.

With some dremeling you can probably get a lot to fit. I've used a real steel charging handle latch on an AEG (had to make it thinner and carve out a huge chunk, and enlarge the hole for the roll pin).
