hdgun Posted January 1, 2017 Share Posted January 1, 2017 Are any of you guys using 38 super with MBX mags? I am having an open STI built but plan on running super not SC. Any issues I should know about or are am I Good to go. Thanks Link to comment Share on other sites More sharing options...
ScottieShootz Posted January 1, 2017 Share Posted January 1, 2017 I had issues so I changed the guts to grams springs / followers and no longer had problems. The mbx guts were fine for 9mm but jammed up when fully loaded with 38super. Ive read some people bent the follower spring up and this fixed their issue but I've not tried it.
