Please help! I am interested in picking up a stainless steel colt officer's model (not the LW model). It is used, but is in very good condition. The asking price is $500. Is this price fair? Also, I have heard that these models often have problems with weak recoil spring plugs and barrel bushings. Is this true? If so has anyone tried a replacement? ie. Wilson's guide rod, reverse plug, and recoil spring package. Lastly, does anyone think that I would be better off spending $700 and buying a NEW Colt CCO? I realize that many people do not like Colts and that their out of the box quality is not the best, however, I would like to purchase one before they go belly up and prices soar. Thanks everyone for your help!
