Powerslide91 Posted December 6, 2012 Share Posted December 6, 2012 I recently picked up an STI Tactical to use in 3 gun. It came with several factory 140mm mags. From playing around it looks like the original mags will hold 20 rounds reloadable. I then tried adding a Dawson SNL quick release base pad and a Grams followers with 11 coil spring. The same tube will now hold 22 rounds reloadable. I have not run matches with these mags so I am not yet positive if they are 100% reliable. I have found a lot of threads on STI mags, but the majority of them are about 40cal. Anyone have any insight on what the max possible might be for the 9mm mags? I guess between some threads that state the 40cal configs are carrying at least as many if not more, and the fact that my XD mags hold 20 but are a bit narrower than the STI tubes, I was expecting a bit more... No real complaints, just curious. Thanks. Link to comment Share on other sites More sharing options...
Quack Posted December 6, 2012 Share Posted December 6, 2012 (edited) I run factory 140mm mags, but had to tune the feedlips to run reliably. Sent from my ADR6425LVW using Tapatalk 2 Edited December 6, 2012 by Quack Link to comment Share on other sites More sharing options...
al503 Posted December 6, 2012 Share Posted December 6, 2012 (edited) Max is 24 tight rounds in a mag that fits the gauge. Edited December 6, 2012 by al503 Link to comment Share on other sites More sharing options...
Aircooled6racer Posted December 6, 2012 Share Posted December 6, 2012 Hello: I will have to check my STI pre ban mags to see how many they hold. I think they hold 23 rounds reloadable with the right base pads. Thanks, Eric Link to comment Share on other sites More sharing options...
TMC Posted December 6, 2012 Share Posted December 6, 2012 (edited) Taran put his parts in/on my SV 140's. 3 will get an easy reloadable 23 and one will get 24 but not reloadable. He says they'll fit the gauge. He might be able to do the same with STI's Edited December 6, 2012 by TMC Link to comment Share on other sites More sharing options...
BMartens Posted December 6, 2012 Share Posted December 6, 2012 I get 23 reloadable using Grams followers and springs with Dawson pads in the SV tubes. That is max with my set up, even with SNL pads. Link to comment Share on other sites More sharing options...
