These were two of my thoughts as well. First, if this is your first handgun, I wouldn't start with a .40 S&W in order to afford other stuff. What's the cost differential between the police trade in .40s and a similar platform, used, in 9mm? Especially in the 3rd Gen pistols, recoil with full factory .40 in G23s is no fun - I can attest to this from uncomfortable experience. The recoil control issues associated with shooting 500 rounds/day of .40 through a G23 or M&Pc are likely to cause significant issues with recoil anticipation, etc.
If a friend of mine had $1K to spend on a starter pistol, accessories, and a training class, and was a NEW SHOOTER, I'd recommend a decent kydex OWB holster (heck - for about $40 you could get a perfectly good "range" holster like an ALS-equipped Safariland - like this one:

Learn the basics with the guidance of someone local, practice until your skills plateau, THEN spend the money on a "name" trainer to get you to the next level. Dry fire confirmed with live fire on the range, with someone you can go back to to verify you're doing things correctly (or to help you fix things that go wrong) is key.
Of course, if you're already confident and comfortable with the basics of marksmanship and gun handling, and you're looking to get to the next level, you may be on track. I still think taking a heavy round count course with any Glock in .40 is a recipe for pain and suffering, though...
