Yup, I've had them myself. Last night, as a matter of fact! Protecting my 15 year old granddaughter from a badguy, wrestled him to the ground and stuck my .38 heavy barrel Model 10 (I don't even own one!) into his side and pulled the trigger six times, to no effect. Then the dirtbag shot me and I woke up.......
