Colt Customer Service
FWIW:
I purchased a Colt Detective Special off GunsAmerica from a gentleman in SanAngelo Tx. (BT). The pistol was basically as new, altho it may or may not have been fired.
I do not collect save queens, I just buy what I like, with the intention of pleasure plinking in mind. When I shot my DS it was WAYYYY off.. It was high/right/left, something.. Anyway comparing it to my other 5 snubby's it was easy to see something wasn't right.
I called Colt Customer Service and they said to send it to them for evaluation, and they would advise what needed repair and how much it would cost to do so..
I shipped my DS to Colt (@$35), and a week later got a nice, brief letter saying the barrel was not "indexed" correctly (or something like that). The problem could be corrected, and at no charge.
Two weeks later the DS was returned, pre-paid, with a nice letter saying the accuracy problem had been corrected, and the da trigger action had been smoothed and improved.. All no charge.
This was a used Colt firearm, decades old, and it was repaired free.. In fact better than repaired because the da action job was just icing on the cake.
All to say I wouldn't get too excited about your present Colt pistol problem. I feel certain Colt will fix it for you free, and just be thankful it's not a Beretta you are having a problem with..
