Turbo0321 Posted May 14, 2018 Share Posted May 14, 2018 I have 5 new SVI 140mm mag tubes for my .40 limited gun and was wondering if I was able to use them for 9mm. They weren’t cheap so instead of buying all new mags for my 9mm 2011 I was curious if a new follower and tuning the feed lips would work? Link to comment Share on other sites More sharing options...
pjb45 Posted May 14, 2018 Share Posted May 14, 2018 Adjusting the feed lips is not a major issue. However, reliability might be a concern since there is a tendency for the mag to become a salt shaker--rattle rattle and jam-o-matic mag. i wonder if adding a spacer like the old STI mags would solve the problem? Keep us posted, please. Link to comment Share on other sites More sharing options...
tcazes Posted May 14, 2018 Share Posted May 14, 2018 I measured my svi tubes both 9 and 40. Other than feed lip dimensions they are identical. Front to back, width, internal dimensions etc. I honestly am curious. Link to comment Share on other sites More sharing options...

Maybe I’ll give SVI and or Atlas Gunworks a call and see what they say but I’m thinking it’s worth a shot. Link to comment Share on other sites More sharing options...

Not sure if you measured incorrectly or if something has changed but the 9/38 super and 40 mags have always had different inside dimensions. I have a 170 40 mag that I changed the feedlips on many years ago and used it for 38 Super and then 9mm. Never had any issues with it so yes it can be done but I don't think it is a guaranteed thing. So proceed at your own risk. Link to comment Share on other sites More sharing options...
tcazes Posted May 15, 2018 Share Posted May 15, 2018 I just used a set of calipers to measure internal dimensions both on the grooves and in the flats. I mean the rounds are all more or less the same oal at their max so it should be more or less the same....thats a lot of feed lip tweaking though. Me personally.....sell the tubes and order some new ones. Never seen anyone have an issue selling svi tubes on here. Link to comment Share on other sites More sharing options...
ParaGunner Posted May 15, 2018 Share Posted May 15, 2018 Why not just try and see if they work? Link to comment Share on other sites More sharing options...
mike4045 Posted May 16, 2018 Share Posted May 16, 2018 I have some 9mm SV mag bodies. Maybe I will try to make them 40 mags. Link to comment Share on other sites More sharing options...
