Glock 43X alternatives from Smith and Wesson?

I bought an M&P 2.0 Metal full size and absolutely love it as a replacement for my Glock 17. I want to replace a 43X for CCW but the S&W lineup is a little confusing. There's the bodyguard line, shield X/plus, and then the CSX E series?

I want to shrink the M&P metal down to a 43X form factor, any recs?
