Possible Major Problems Coming With Glock 43x/48 15 Round OEM Metal Mags..
This video from SPN Firearms explores a potential long-term issue with Glock 43X and 48 OEM 15-round metal magazines when used with factory polymer magazine releases. The presenter observed wear on a metal magazine and a subsequent magazine drop issue on a modified Glock 19, theorizing that the metal magazine's interaction with the polymer mag release can cause wear over time, potentially leading to reliability problems. Further testing is planned to confirm if this metal-on-polymer interaction degrades the magazine release or the magazine itself, impacting firearm function, especially for those who train frequently.
