PharmDShooter Posted November 22, 2018 Share Posted November 22, 2018 I’m thinking about adding some Taran Tactical baseplates to my STI 140mm magazines. Will the 7mm plates keep the magazines legal length or do I need shorter? Thanks in advance! Link to comment Share on other sites More sharing options...
muncie21 Posted November 22, 2018 Share Posted November 22, 2018 For USPSA, you'll want the 3g or 4g ones. Link to comment Share on other sites More sharing options...
Avedis Posted November 23, 2018 Share Posted November 23, 2018 I believe 4mm, see video below at 0:50 sec, (gen 2 mags) https://www.youtube.com/watch?v=tdM0gtYmUTs Link to comment Share on other sites More sharing options...
HI5-O Posted November 23, 2018 Share Posted November 23, 2018 FYI, I got the gen2 STI 170 tube and like the video recommended I got the TTI 4g base pad. That combination didn’t fit the gauge. I had to get the 3g base pad and all is well. If you know someone with the base pads, ask them to see what will work on your tubes. Link to comment Share on other sites More sharing options...
Novagunner Posted November 23, 2018 Share Posted November 23, 2018 Weird. According to the spreadsheet on the page below, STI 140mm should be a 4 mm. I have them on my STI mags. I'd give them a call. They've have great service whenever I have had an issue.https://tarantacticalinnovations.com/base-pad-for-sti-sv/ Link to comment Share on other sites More sharing options...
molson Posted November 23, 2018 Share Posted November 23, 2018 HI5-0, i had had the same experience as you. Gen 2 required the 3G pads to fit the gauge. Mike Link to comment Share on other sites More sharing options...
Balakay Posted November 23, 2018 Share Posted November 23, 2018 You can only use 7mm basepads with 140mm mags if you are shooting Open. For Limited, typically use 4mm but as stated above, gauge it because you might need a 3mm Link to comment Share on other sites More sharing options...
Aircooled6racer Posted November 23, 2018 Share Posted November 23, 2018 Hello: You can use the 4mm TTI. You may have to take a little off the top of the magazine to fit the gauge. OR you buy the 3mm base pad and cut 1/2 coil off the spring and it will hold the same as the 4mm base pad. OR leave the spring alone with the 3mm base pad and it may hold the same as the 4mm base pad. So just buy the 3mm base pad and check the gauge. Thanks, Eric Link to comment Share on other sites More sharing options...
