Extend your Glock 21/41 from 13, to a full 17 rounds of firepower! Work with CARVER Custom 21 Magwells, all models.
Built for USPSA's "Limited" Division, the finished magazine is 140mm long, as measured down the back (versus about 120mm stock).
Ships with a custom-made Wolff spring.
HISTORY: Glock's early .45 ACP mags used a 9mm-width spring -- with mixed results. The newest design uses a full-width spring, eliminating the problems of the earlier style. When the wide springs became available, we re-designed our old G21+4 to take advantage of them -- and extended the length to fit the new USPSA gauge at the same time. The result is a +4+ situation that's simpler and more reliable than the old skinny-spring G21.
NOTE: Our new springs don't fit the older skinny-spring followers very well. They will work, but you're better off getting new mags with the new chisel-nose followers.
