Glock 17 outperformed 8 different pistols from five other established manufacturers (Heckler & Koch of Germany offered their P7M8, P7M13 and P9S, SIG Sauer of Germany bid with their P220 and P226 models, Beretta of Italy submitted their model 92SB-F, FN Herstal proposed an updated variant of the Browning Hi-Power and the home-grown Steyr entered the competition with the GB).
