John; As we had discussed recently, I installed a plug in my Smith. I had never had an IL failure, but, with the frequency that the failures take place, I was not going to take the chance. In a self defense situation a failure could be catastrophic...in a hunting situation a failure could result in the loss of that prized trophy, and, from what I have heard/read, in all situations you have a gun that is locked up with a loaded round in the chamber and a cocked hammer!!! You are performing a vital service to those that should be seriously considering "The Plug" and you efforts are to be commended....If nothing more, the cost of The Plug insures peace of mind, and possibly protects the Smith owner from a failure to fire when least expected!
