I'm a less than 1 year Texas resident and have been to multiple guns shows here (DFW area)... Haven't seen any such vendor, much to my chagrin. In my former state of residence, such services were readily available at basically each show. Bummer! HOWEVER, I'll gladly trade not having such a vendor available for the privilege of living in Texas!!!!!
Sent with the good grace of God.
I used to see them at motorcycle shows but I haven’t been to a motorcycle show in years. I never see any earplug guys at gun shows.
