Jimcbang, welcome to IDPA. Since you allready have the S&W M19 and holster, I'd go to the next gun show and find some HKS speed loaders, and some used PD leather or synthetic holders. This will get you by until you have had time to check what the revolver shooters at the club are using. Remember, stay away from pure competition gear. Check
www.idpa.com for the specifics on revolver gear rules, and check the sites for Safariland, or Bianci gear (sorry, I don't have the addresses available
). Again, welcome and good luck
