gnappi Posted July 6, 2020 Share Posted July 6, 2020 I have Witnesses in .38 super, .40, and 10mm and found that some mags (all Tanfo supplied) can be reliably pressed into service for use in other calibers. My .38 super mags work 100% of the time for .40 and .9mm. I have plenty of 9mm mags but need .40's as well as .38's and I'm wondering if instead of buying a bunch of both, it other Tanfo owners have used super mags with success with 9 as well as (more importantly) with .40?

Dan4147 Posted July 6, 2020 Share Posted July 6, 2020 gnappi I have a GT 9mm. Using the Tanfo and K9 mags (with spacers) my max oal is 1.140. I got a 38s mag to try so I could load out to 1.165 for powder flexibility. I never did get the 38 mag to run/feed properly and gave up. I don't know why. Now that I have stroked the GT I may give it another shot. Link to comment Share on other sites More sharing options...
Maurice Posted July 7, 2020 Share Posted July 7, 2020 Certain 38 super mags work, others do not. I found that older 38 super Tanfo magazines work in my domina, and also use the k9mags that I believe come with the newer 9mm dominas. I am loading to 1.60 with no mag issues so far. Gun runs really good using an 8lb recoil spring. Could be a 9lb, as I got my springs mixed up. Link to comment Share on other sites More sharing options...
Mlussoro Posted July 9, 2020 Share Posted July 9, 2020 I run 40 reliably in my 38s mags as well as my MBX mags, 9 will run out of 38 mags all day swapping the follower to a Grams TSO , run my GT with 6lb wolf functions flawless Link to comment Share on other sites More sharing options...
