There's a lot of good info in this thread and some bad, so check things out for yourself.
I buy LOTS of guns through Bud's Police. Too many some would say. As for the rebate, I have received it three times. From what I read, I know I wasn't eligible for at least one rebate I received, but sending in the paperwork was easy and the check cashed just the same.
The night site version does cost more than $399. Most will come with three mags but the Shield and 45's do not.
Which is the best to carry? The one you like to carry.
Yes the 40 can be changed to a 9 with a stock barrel swap ($65), and it's more reliable with the stock barrel than the SL conversion barrel (that's with my own research on this forum only). Recently guys have been doing some cutting and fitting 40 barrels on 9's, so I guess it is possible. .357 and 40's share mags, 9's do not, although you can get by with a 40 mag in a 9, I wouldn't bet my life on it.
Will a 9 do everything a 40 will? My magic 8 ball says no, but I'm not arguing that point. I'll carry a 9 as readily as a .45.
Speaking of .45's: Did you notice Bud's has the 1911SC E series for only $948? That one is on its way to my FFL already!
Good luck with your decision, but let me toss in my own advice for anyone looking at M&P's: If you don't have an M&P yet, they are nice. And the last one I would ever sell is a compact. The most versatile is the .40c because it can become so many other guns so easily. The 45c is a shooter and carries very well too!
