from what i have seen for pricing the sigma is a great value dollar for dollar.
i had the same 3 on my shopping list plus the glock 26. the glock did not fit me so i looked at the other 3 but settled on the mp9c as i wanted something small to easily carry. for me it was down to the xd or the mp and the mp compact had slightly more rounded corners then the xd. close the eyes, pick it up. point and see if it feels good and points right for you.
