I am on the edge of the seat for sending in my SB-1 reciever for a 357 mag barrel to be fitted up. Then in a pm The janitor was telling me something about the 357 having pierced primer problems of some sort. Can someone comment on this? I dont need anything causing a injury as it will be a youth gun. Also, is the web site for nef barrel program still currant with there prices? I hope they still have open sights to.
