zzt Posted April 8, 2018 Share Posted April 8, 2018 Tacsol does. https://www.tacticalsol.com/2211-series/ To the best of my knowledge, they are the only one who make a conversion that will run 100% on a 9mm 2011. If you have a plastic grip and squeeze hard, the metal double stack mags won't drop free. Some of them won't drop free anyway. Same with the plastic mags. The CWA and Marvel and Nelson conversions definitely will not work without modification to accommodate the 9mm ejector. Link to comment Share on other sites More sharing options...
38super Posted July 23, 2018 Share Posted July 23, 2018 Remove the ejector, just remember to reinstall with your CF upper. Link to comment Share on other sites More sharing options...
ksf141 Posted August 5, 2018 Share Posted August 5, 2018 STI also produced an "STI" branded 22 conversion upper for some time. I believe it was either just a re-branded Marvel or Tacsol conversion but either way it was marketed directly to STI owners for use on their STI guns. You can find them on gunbroker every now and then, in fact I think there is one on there right now. If you had issues, might be able to bug STI customer service.
