I was in my local Walmart today and in the sporting goods department the have a huge selection of AR type rifles. They had Colt, Sigs, DPMS, S&W'S... The prices were lower than several of the larger local gun shops. They had a Sig M400 for $890, several hundred less than the local gun store (not wanting to debate the evil WM vs the mom and pop here please). I was at the largest local shop, Shoot Straight, and asked about the price difference. They claimed it is not he same gun. I told them it was an M400 with no different markings than the one in their store. The clerk told me "yes on the outside, but it is different on the inside" with lower quality parts. Now I do recall that Beretta made a shotgun, the 391 vs 390, for Walmart, but this is a Sig M400 not a 401 or something like that.
What is the deal here? The M&P looked identical to everyone I have ever seen as did the Colt. Are these the same guns or is the clerk correct that they are lessor quality? I have a hard time believing that a M400 with no special markings is not the same as the M400 in the gun shop. How would you ever be able to tell the difference with a resale?
