Concealed means concealed.
Also, my GWP gives me cover in 35/50 states. I wouldn't call that "almost truly worthless."
Also, also...I don't remember the last time I filled out a 4473, so skipping the NICS check isn't even a factor for me.
True, concealed is the big difference. 25 of those 35 states have constitutional carry so your GWP doesn't matter. Of the remaining 10, more than half allow for legal open carry, no permit required. Usually if the state doesn't allow for no permit required open carry, they also don't recognize your GWL, like IL, NY, NV, NM, MN, CA, Etc.
