I got a great deal on my M&P40c a couple of months ago from Sportsman's Guide and was expecting the standard 2 10 round mags, but when I opened the blue plastic case, it had two finger extension mags and a flat base mag in the gun.
So, was this a mistake by S&W or maybe some kind of promotion that SG forgot to put in its advertising?
I'm not complaining, it just seems weird that they'd just throw an extra mag, worth ~$25 and not say anything about it. I'm like most of you and factor the cost of magazines into the total budget of owning a particular gun.
