I personally like these kits. I would pay $20-30 more for a gun that includes this. I've actually been trying to procure the holster and mag holder for my M&P. I like that Blade-tech included the S&W M&P logo on the holster as well. I have also found these on Bladetech's website but I don't want to pay the new price for this ($30 just for the holster)plus the shipping they charge. Let me know if you are interested in selling the holster and mag holder (qty 2 mags) for a reasonable price.

here is the Blade-tech holster link:
