Everyone I need some advice. The dealer in my area has a .40 cal USP compact for sale. Asking price is $550. The gun looks to be in good condition, comes with 2 10-round magazines and a HK case. No manual or accessories. The Date code on the left side is AC which if I'm correct indicates a production date of 2002. Is that too old to purchase? Should I be getting more of a discount due to the guns age? Let me know, any advice would be greatly appreciated. BTW I already put down 100 bucks to hold the gun until I get you guy's advice! Thanks.
