MedicAJ Posted March 17, 2016 Share Posted March 17, 2016 What is the difference between 140mm STI 9mm and 38 Super mags? Are the bodies the same but with a spacer? Are there any other differences? Thanks! Andy Link to comment Share on other sites More sharing options...
4me2ply Posted March 17, 2016 Share Posted March 17, 2016 (edited) As far as I know it is the same mag. Most 9mm guys run the spacers in them with the 9mm follower which is shorter(front to back) Edited March 17, 2016 by 4me2ply Link to comment Share on other sites More sharing options...
echotango Posted March 17, 2016 Share Posted March 17, 2016 (edited) Same mag. To be more specific, what quack said below. Edited March 17, 2016 by echotango Link to comment Share on other sites More sharing options...
Rob1125 Posted March 17, 2016 Share Posted March 17, 2016 Same mag body, just a shorter follower and a spacer for 9mm. I just repurposed all my old .38 super mags to 9mm. They work 100%. Link to comment Share on other sites More sharing options...
Quack Posted March 17, 2016 Share Posted March 17, 2016 (edited) Spacer and follower is the only difference. Feed lip specs are a little different too, if you tune them. Edited March 17, 2016 by Quack Link to comment Share on other sites More sharing options...

EkuJustice Posted March 28, 2016 Share Posted March 28, 2016 Ya there is a different follower. The difference is spacer and 9mm follower in a 38 tube Link to comment Share on other sites More sharing options...
Quack Posted March 28, 2016 Share Posted March 28, 2016 The 38S follower is the same as the 40 follower too. Link to comment Share on other sites More sharing options...
