I believe a movement has already started. We are seeing a general push back on the government telling us what we can and cannot do, especially on a state level.
We've seen report suppressors (AKA "silencers" but I hate that name) get legalized for possession and hunting in several states, including Iowa. We've seen movements towards shall issue carry and permitless carry in several states. We've seen marijuana be legalized on the state level, I just heard on the radio about several states that had a vote to legalize recreational and medical marijuana but I don't recall the exact results.
Concealed carry reciprocity, on a state or federal level, would certainly be a gain and I'd welcome it if it came to be. We've seen several states get permitless carry in the past decade, it would be nice to see that trend move forward even if it did not come to Iowa right away. We have shall issue now, and a pretty good reciprocity, so I'm willing to be patient to get something better.
While I can wait for permitless carry I do recognize that there are times where bringing it to vote has better chances than others for a pass. I believe that we will see a good opportunity for that soon.
