I at one time went to a lot of gun shows, Garden City, Salina, Wichita,KS, and Tulsa, OK.
The first incident in Wichita, a police officer picked up a pistol off a display table and shot himself in the leg.
The second incident at Salina, a friend picked up a S&W 9MM from a table jacked it open and expelled a live round, it also had a fully loaded magazine in it.
The third incident was at Garden City, person setting up his display picked up a 7MM Mag. which discharged and hit a women in the upper body killing her.
I haven't gone to many gun shows since, a lot of careless people out there and I may have used up my luck.
