As a first time gun owner, I would HIGHLY recommend that you pass the .40 and go straight to 9MM. 9MM offers faster split times, is cheaper, has less recoil, has more capacity, and offers the same ballistics when using premium jacketed hollow point ammunition.
By the way, I am an ex-cop, witnessed hundreds of shootings, attended autopsies, participated in numerous ballistics workshops. I've spend hundreds of hours studying ballistics, shooting through barriers, shooting ballistics gel, etc. My conclusion is that 9MM is highly beneficial over .40.
Read this earlier thread, especially my comments on .40 vs 9MM.

Also, the Glock 23 and 22 are Glock's least reliable pistols, especially if you plan on mounting a weapon light to them.
The Smith & Wesson M&P and Glock 17-19 are solid platforms.
