Blythes does the same thing. A buddy of mine traded a sig 1911 for a glock 41 with an extra mag thrown in worth at thier prices 760. They put the sig up for 999. Brand new wholesale was 850.
Always best to do the research and know what prices are BEFORE shopping. Know exactly what ya want (handle it, etc.), then buy from the place that has the price and service that best suits your needs.
GM is a terrible place to buy firearms. Was very excited to see one go up on my side of town, until I saw the prices. And personally, I would rather support the local gun shops instead of the big chain stores.
