Many of the posters have bought guns that are worth more than they paid. However, the real money in guns, the way the dealers do it, is to buy good guns 25% below the market and sell immediately. There is no way you are going to improve on 20% profit in one week. Keeping a gun for five years will not come close to the 20% per week appreciation no matter what kind of gun it is. Ask a gun dealer how many guns he has in the back room that he plans to bring out in August of 2012. He has none.
