not surprised at all!!! guys do this all the time... why, i have no idea. If you buy a gun and take it home and never fire it, then a year later decide to sell it, it is not worth retail prices!! why?? because gun manufacturers come out with a new model every year. Computers are a good example of this logic. Computers that are a year old are not worth the same as a new one, because the technology has changed. guns are similar. Fired 100 rounds through it, does not mean it is worth retail prices!!! this is not hard to figure out, but sadly to many people seem to think otherwise. Another example would be that Guns are like cars, they depreciate!!! hate to burst the bubble on this one but its true.
