Valparaiso resident Vincent Fischer and his 14-year-old son were hunting at the Kingsbury Fish & Wildlife Area Sunday morning, when Fischer tried to place his pistol in a holster and it instead fired into his right leg.
Fischer's son immediately used a belt to create a tourniquet and called 911, according to the Indiana Department of Natural Resources.
Fischer is now stable and he's expected to recover.
Indiana Conservation Officers are investigating the incident.
