I am new to this forum and to handguns in general. Have read much regarding the issue of 9mm/.40/.45 for SD/HD.

Aside from that issue, I would like to hear input regarding/comparing the issue of recoil from the M&P 9, M&P 40, and M&P 45. I do understand that the recoil increases in the order that I have listed them, but beyond that basic fact, how do the forum members assess the relative differences?

To put it another way, if recoil was the only issue on the table, what would cause one to select one over the other.

(I did a general search but could not find anything specifically on this topic.)

Thanks for for your input.
