Saffer Posted December 16, 2011 Share Posted December 16, 2011 Does converting 38 Super STI magazines to 9mm Major magazines just entail adding a spacer? If so, are you not also required to change the follower and spring to a set that have a narrower breadth, to allow for the spacer? If all of the above are true, would changing the internals on tuned magazines affect the maximum loading capacity with the new caliber? In other words, after the conversion will the magazines still achieve maximum capacity? Any feedback would help. Quote Link to comment Share on other sites More sharing options...
