Following the recent arrival in Brazil of test samples of the .40 S&W Glock Gen5 pistol that emerged as the winner of a competition to supply 5,000 units to PMESP – Polícia Militar do Estado de São Paulo (São Paulo State Military Police), it has been disclosed that the very initial testing process, carried out on January 31, 2018, suffered a major setback. It just so happened that the 10 specimens at hand displayed dimensional discrepancies in the accessories rail of the lower frame. The Picatinny type (aka MIL-STD-1913) rail was a specific contract requirement, but a note signed by Major PM Marco Aurélio Valério, the PMESP officer in charge of the Technical Commission, says that all testing procedures were suspended until further, more detailed measurements are taken.

According to a PMESP official statement, actual dimensions of the Glock G22 Gen5 accessories rail did not conform to the Picatinny standards, as specified by the contract requirements.
