Anyone here have any opinions on the Colt Peacekeeper .357.I have the opporunity to buy one NIB for $350.00.My understading is that they were made for a short period in the 80's for the police market,and are based on the Colt Trooper.The one i am considering has a flat black,almost parkerized finish and Pachmayr grips w/the Colt medallion on them.Thanks in advance for any info/opinions.
