Now that I know that you, a minor, are the ultimate end-user of the product, there might be legal implications with such a transaction.
Plus, anybody who wouldn't be open to at least $800, wouldn't be able to get anywhere with me in negotiations.
I can either return the darn thing and get my money back (from the manufacturer), get a new gun (from the manufacturer), return it to the retailer, or if nobody will take it back, dispute the charges as provided for due to a refusal of the retailer to recognize my rightful and legal revocation of acceptance.
I'll just tell the manufacturer that I am going to carry the firearm, use it for defense, and when I get hurt/killed because it fails me, they will have a wrongful death lawsuit on their hands, and a product liability lawsuit... Strict liability maintains that the consumer doesn't even have to stop using it once they know it is defective...

Besides, they repeatedly assured me that it will work and it just needs "time" so I suppose I am going to just tell them that I may very well one day be in Iraq and/or Afghanistan and I will using this firearm as a sidearm, and my dad (executor of my estate) will be quite aware of this fact, and will be retaining an attorney so the second I die when this pistol fails, they will be sued until they are bankrupt...
Of course I'd prefer NOT to use this pistol in any sort of capacity, but I am going to tell them that as long as it remains in my possession or on the market, or in anybody's possession, it is setting them up for a mega-lawsuit... They need to give me money, take back the pistol, and throw the thing into a blast furnace before somebody gets hurt when it fails them at a crucial moment...
