I have DeFoor sights I'll give you if you promise to put the XS in the garbage.

Knock those sights off and you'll have something. Big dots are, IMO, gimmicky trash. I'm sure someone will be along shortly to tell me how wrong I am, but if they are the type with the very shallow rear sight they are fantastic sights for distances you don't need sights for and terrible sights for distances you do need sights for. There are plenty of quality sights that draw the eye to the front, make it easier to shoot with both eyes open, and still allow precision at reasonable handgun distances.
I'll keep this short.
I'm not saying .40 S&W is done, etc. but a lot of the calibers you mention while still in circulation aren't receiving the same load development attention that 9mm enjoys.
One more reason to go 9 in my opinion. The circumstances regarding available lightly used .40 trade-ins will not be here forever just like the .357 quality revolvers aren't anymore or Garands or 1911's, etc, etc.
I wanted to steer the OP in the best long term direction for platform support; basically give advice I would want to know if I was in his position.
Anyway, he's made his decision so it's a moot point now.
