I have a 24 hr hold on this gun at a local gun store. It is LNIB with all papers, warranty card, Master lock (unopened) spent case etc. The previous owner traded it for an automatic and probably shot less than 20 rounds through it. The store is asking $459.00... Is this a good/fair price? This is a .45 Colt Mountain gun built in 2002 (based on spent case in envelope) with what looks like a rosewood finger groove grip. It feels great and I can get it 6 months same as cash.... It's tempting... Should I buy it?? Opinions as to quality, accuracy, durability and overall value are needed immediately!!! Thanks
