That's a pretty good price to get you into the M&P platform. From there you can go to .40 and 9mm, so its pretty versatile. As far as the .357 Sig caliber goes, I'm not a huge fan, mainly because of price, and availability concerns. The only way I'd do the deal though is if I planned on sticking with the .357 as my main cartridge, otherwise, I'd look for the same kind of deal on a .40 and never think twice about it. YMMV.
