Looks like Sig and S&W made a handgun by joint committee.

I was thinking Hipoint fucked an M&P.

It does look ugly. Never like the Chamber indicator on the top position.

It's really a lot more slender than I expected. I don't have very big hands and I'd like to handle with a bigger backstrap.

They were across from us at the IWA show in Germany. I got to play with it a lot. Not the biggest fan of the frame's material aesthetically and the backstrap geometry has a lot of flat edges that look odd. The geometry however does not feel bad when gripped in the hand. The gun sits very low in the hand and you can get a very high grip on it. The trigger is where it shines, better than a PPQ, and a super short reset that rivals the CANIK TP9 ELITE Executive's reset. The gun feels awfully small for the capacity that it has. I was interested in one, but am a bit weary due to the possible difficulty of getting any support should something go wrong.

If I ever put another set of mags into my collection, Arex will almost certainly get the nod... if these were compatible with the P-series Sig's for mags, I'd own the full spectrum already.

The Rex weighs 2.4 ounces less than the Glock 19, and is also the thinnest 15+1 9mm striker fired pistol made.
The trigger reset is shorter than the PPQ, so I don't know where you come off stating "Hipoint fucked an M&P", since you obviously did zero research prior to your statement.

Looks pretty good
