The MATRIX: The Official List of GLOCK Pistol Serial Number Letter Prefixes and Ship Dates

The GLOCK Collectors Association has documented GLOCK serial numbers and letter prefixes since 1995 and compiled them into the MATRIX, along with model names, ship dates, model generation, model frame sizes, model calibers, and more. It's the most complete and official record of First Run GLOCK Pistols in the US. The MATRIX is included in the Master Journal and part of all membership packages.
