Since mid-2017, news has circulated in the local Brazilian media concerning the proposed acquisition of 5,000 .40 S&W pistols by PMESP – Polícia Militar do Estado de São Paulo (São Paulo State Military Police) as an initial step to start replacing the agency’s inventory of Taurus-made models in general use since the 1990s. The supply tender was particularly significant since it would be the first time that foreign companies were participating, other than the local Taurus and IMBEL concerns. By the end of 2017, competition had been narrowed to three models, the Beretta APX, the Glock G22 Gen4, and the Sig Sauer P320.

On January 8, 2018, PMESP’s Centro de Suprimento e Manutenção de Armamento e Munição (Armament and Ammunition Supply and Maintenance Center), in charge of the public tender, announced that Glock had emerged as the winning company based on the lowest unit cost offered for its pistol: R$ 1,600 (about US$ 500), Beretta coming next at a unit cost of R$ 1,677 (US$ 524). Sig Sauer had since abandoned the tender.

Glock was given the date of January 18 as a deadline to supply a number of pistols to be submitted to a comprehensive test program that is reported to include NATO, NIJ, and German standards, the final signing of the actual purchase contract depending on the test results.
