About The St. Louis International Cartridge Show (SLICS)

The St. Louis International Cartridge Show (SLICS) began in 2000 after moving from Chicago where it was known as the Chicagoland Show. This centrally-located show has been the largest and most attended show for cartridge collectors for over 40 years. In addition to collectors, the show is well-attended by those in the forensics industry as well as other government agencies across the world.
For many people this is the only show they attend each year and many take days just to travel to this show from around the country and world. It is the premier event that everyone recommends and sets on their schedule for the week leading up to Easter every year.
