from the Colt web site
For your continuing support and patronage of Colt products, we have designed this COLT® ORIGINAL PARTS section in a way that will make ordering more convenient and easier than ever before. We at Colt’s Manufacturing Company, Inc., know how important it is to keep our customers informed of any new models as well as any enhancements to our current models. For your convenience, this portion of our Web site was developed to continually provide you with any revisions in current part numbers or new part-number listings. We want to process your parts order promptly and correctly. A parts order must include the specific model, finish, caliber, barrel length and the part number. Order each part by part number and by the part name exactly as shown.
