Slim Shield is good for me. I have two of the 1.0s. I also have a MP 2.0 with short 4 inch barrel (i think), and it seems a lot lot bigger and heavier with the double stack mag.
Maybe the 13 rounder Shield would fit in the middle as far as comfort. I really never notice the shield 1.0, really comfortable.
S&W did a good job with the Shield and MP.
