I inherited a Savage 340B .222 form my grandfather. I love to shoot it but it has misfired twice. Once ant the range when I closed the bolt it went off and the first time it was set down on the butt of the stock and it went off. I would like to try and get it fixed. I guess it has to be in the trigger mechanism, do they make a replacement for them any one is aware of or is there a gunsmith on the south side of Houston someone recommends
