PopVox is fine, but I've already provided a
link to find and contact your senators easily --
directly through the Senate website. I've also provided the easiest method to contact your Senators using
the Gun Owners of America tool. I've used their contact forms many times and my messages have always been delivered because I get responses from my reps/senators. GOA is one of our country's oldest and staunchest gun advocacy groups. These links are at the top of the post.
