I've spent quite a bit of time traveling around to a lot of gun shows. Living in Texas has a lot of big gun shows all across the state. I've always had issues finding a good website that lists a lot of shows. I've used Gunshows Usa for awhile, but that site is more confusing than it should be.
Needless to say I've seen a lot of people in the forums looking for a good site to find gun shows and what not, and recently I heard about one at a gun show near Dallas. http://www.YourGunShow.com
This site is based out of Texas and I was suggested it at this gun show. I gave it a look and it's really well organized. It also covers the whole country and allows you to enter your own gun shows.
So I post this cause I want to help all those who are in the position I was in. I hope this website helps you like it helped me.
