in ND, two classes of permits. one is obtained with a fee and open-book test/4-hr course. reciprocity is more limited. other includes the first set, plus a shooting course (if you can hit the broad side of a barn, you're good to go). reciprocity is wider, only a few states where it isn't accepted (and they don't accept any). got mine when I hung up the sam browne belt/badge, cuz I had a better idea than many about how frequently people walk among us with bad intent.
I carry IWB, strong side, with either my .45 SW (my 'fall-to-spring' choice where clothing is bulkier/layered) or my Ruger LC9, which could also just be in a pocket.
I hope to never need to use it, but I'm prepared and able should I choose to. Many here are alarmed with the influx of thousands pursuing big money in big oil. I was alarmed long before then, but the landscape has certainly gotten more interesting. Permit holders are growing exponentially - I just hope everyone is able to discern when and how to use, and I hope the low-life's pick on the wrong person when they do what they do - victimize and terrorize their most available target(s).
