Complete magazines for platforms outside the standard competition lineup are consolidated here, covering Glock, HK, Ruger, M&P, Sig, and other manufacturers whose pistols see use in USPSA Production, Carry Optics, and IDPA divisions without a dedicated brand-specific category. Glock shooters running Production or Carry Optics builds will find magazines sized to their generation and model, HK and M&P competitors get factory and aftermarket options matched to their platform's magwell dimensions, and any additional manufacturer not covered elsewhere in the magazine lineup is stocked here as it becomes available. Feed lip geometry, follower design, and spring rates on these magazines are matched to each platform's specific cartridge and capacity requirements, whether you're loading 9mm for a club-level Production match or building out spares for a duty-pattern pistol crossing over into competition. This lineup exists specifically to catch the platforms that don't fit neatly into the dedicated 1911, 2011, CZ, or Sig magazine listings, so if your pistol isn't listed under its own brand heading, check here first. Fast same-day shipping on most orders at Shooters Connection.
