I've been kicking around the idea of picking up a USPc .45 for awhile. I thought about buying new , but recently found a "used" 99% USPc .45 in a local store . Looks unfired, but it has been preowned. It's a 2012 mfg with box, 2 mags, std sights and decocker. $545 sticker, so under $600 OTD. Is this to good to pass up or should I continue to search ? Thx
