Going to go out on a limb here, GET the M+P, I have one and love it.

, than take the wife to dinner or get her a SPA gift certificate, flowers, massage, etc,...
After my last pistol purchase (EAA Witness .40), I took her to dinner gave her a neck rub, and the next day while in my "gun room"
was told I had an "arsenal", didn't need to buy anymore damn guns OR ammo, and when is enough enough?
So, chalk this one up to "I don't know", do what that little voice tells you, and love your wife.
BUT if you can squeak it,......... Get the M+P, there's a rebate going on,...
