Well, yes and no...if indeed the only difference between the "1.0" model and the 2.0 model is the designation on the slide...then you could argue that you got the 2.0 in all respects except the designation on the slide. You could also argue that you didn't get a 2.0 model, since it was not so marked.

I doubt that these guns will become collectibles, or that having the 2.0 designation will make it worth more. As Shakespeare said, "A rose by any other name still smells as sweet" or something like that. Maybe S&W will give you a free mag or two, or perhaps exchange the slide, if it really bothers you that much.

The real question is, are all the features the same? If there is a difference, be sure to post it here...not that I plan to buy a Shield 45 2.0, for a minor difference, but I'd just like to know.
