My SP101 357 was replaced by the ammunition company the other day after it blew up in my hand back in December, I wasn't hurt just a little shook up. The stainless steel cylinder was actually cut in half and the entire gun was ruined. The range guys and I searched for the other half of the cylinder but we we unable to find it. It may have blown up into little pieces or got lost up in the rafters above. Thank god the cylinder went up toward the ceiling like it was designed to do. I was using Home defense JHP 357 loads. We found several unspent bullets that were dented with tips that had fallen off. I had shot five rounds successfully, then I reloaded. The first shot after the reload the gun blew up. I was still holding it after it blew, this was a very weird and surreal feeling. I was sort of in shock and thought I might have been hurt. I had checked all around my body to see if I had been hit. I have chosen not to mention the brand of ammo as I believe an investigation is still ongoing. I am so happy I got the gun replaced by the ammo company the other day. As you can imagine I haved been going through withdrawls the last couple weeks not being able to shoot. Just thought I would share this experience with you. I still Love my SP101. This is a great gun!
