there is one being sold locally for 599 obo. its a colt 1911a1. looks to be in good shape, comes with 3 magazines. one of the mags looks like its an extended round of some kind, its considerably larger then the others... by about an inch and there are 9 holes in the side im assuming are for viewing how many rounds are left. hes including a holster too, which i probably wont use. is this a good price if its in good shape? if not what should i offer.
