I have been doing some research on firearms law lately, and have run across a lot of people using the phrase "conceal carry" to describe people carrying a concealed firearm. In my opinion, this should be "concealed carry", since if asked the question "how are you carrying your firearm?" I would reply, "I'm carrying it in a concealed fashion," not "I'm carrying it in a conceal fashion."
Still, am I wrong? Would it be equally correct to use the phrase "conceal carry" in some circumstances?
