Glock competition magazines, extended-capacity options, and factory mags for G17, G19, G34, G35, G43X/G48, and PCC-format Glock-pattern pistols — stocked here in 9mm, .40 S&W, and .22 LR for competitors, trainers, and PCC builders.

Your magazine selection is part of your equipment strategy. USPSA Production and Carry Optics competitors running G17s or G34s need reliable 17-round or 18-round mags that feed consistently under hard use and seat positively in race pouches. PCC and Open division shooters building extended-capacity loadouts have options here from 22-round through 50-round drum formats.

Factory Glock magazines in standard capacities are stocked here for G17/G34 (17-round), G19 (15-round and 10-round), and G35/G22 in .40 S&W. MBX Extreme 155mm and 170mm steel magazines are the go-to competition extension for USPSA Open and Limited shooters running Glock-frame guns, with MBX's Defender Series covering carry-capacity builds for the G17 and G19. Shield Arms S15 Gen 3 expands the G43X and G48 to 15 rounds in a flush-fit form factor. ETS magazines provide high-capacity polymer options at 17, 22, 30, and 40-round counts for training volume. MagPul PMAG GL9 covers 15, 21, and 27-round configurations for G17-footprint guns, plus the D-50 drum in both pistol and PCC configurations. Mec-Gar extended mags in 18-round capacity round out the competition-grade options for G17 and G19 platforms.
