Why Shield Arms Mags are NOT the Answer for the Glock 43x and 48
This video critically examines the reliability of Shield Arms S15 magazines for the Glock 43X and 48. While offering a capacity increase to 15 rounds, the presenter highlights significant inconsistencies in performance, with some users experiencing 100% reliability and others facing frequent failures to feed and lock back. The presenter personally experienced issues with springs weakening over time, leading to a decision to revert to OEM 10-round magazines for primary carry, while still carrying a Shield Arms magazine as a backup.
