I talked to Kate Fredette ( 1-800-331-0852 Ext. 218 ) from Smith & Wesson Customer Support in regard to the Model 624 recall. She said that the problem is that the ones produced between Jan. to June of 1985. The company that supplied the cylinder steel did not meet S & W's specs. They have to magnaflux the cylinder to check if they are ok. So far they have only found one bad. She requests that if anyone calls her that they have the serial number and leave it with her voice mail. Then when she returns the call she will have looked up the date of production and be able to provide the information to the caller right away.
