If it is in the Reliant Center - then in my opinion - yes. At one time I thought they were the best Houston area Gun Shows.
HGCA recently had a show in the Stafford Center. Intel I received was that it was disappointing.
It used to be that many out of state and out of area dealers would attend the HGCA show, but when fuel prices went over $2.00 per gallon the quantity of vendors went down. Northridge used to display at HGCA but hasn't now for years. It was great being able to pick small parts from bins.
It often still is a good show. Schedule conflicts have kept me away.
