I'm looking to get a scoped pistol holster from Pistol Packaging for my Ruger Blackhawk hunter. But can't seem to find out if they offer a hammer thong or retention strap to keep the gun in. Do any of you have this style of holster? How is the gun held in? Does it carry well on a normal gunbelt? Also what do you think of these holsters? Thanks for any information it is greatly appreciated.
