Thanks for the info fellas. KSR I live in the Union area,which is about 50 miles west of STL.This gun is unfired,but when i first got it i had to play with it a little.In the process of cocking the gun maybe 20-30 times a very faint ring is starting to appear in between 1 or 2 of the notches. btw it is nickle finish.It is hard to see and could probably still be polished out but i dont want it to get any worse. Was thinking of sending it back to Colt to have them fix it but if i could get it properly done somewhere around here i probably would. Thanks again.
