Jonesjohnm Posted July 8, 2017 Share Posted July 8, 2017 I picked up a new STI 170mm 9mm magazine about a month ago. I installed a Dawson Prec plus 1 basepad. Since doing so the follower seems to get stuck very low in the magazine and turning my mag into a pepper shaker.... any ideas?

Aircooled6racer Posted July 8, 2017 Share Posted July 8, 2017 Hello: Try a different follower/spring. I have not played with the new STI mags yet so I can't say which follower/spring setup will be best. I am not sure if the mag will need the rib lengthened also. It is called a "Salt Shaker" by the way and they suck. Thanks, Eric Link to comment Share on other sites More sharing options...

wgj3 Posted July 8, 2017 Share Posted July 8, 2017 You can see the ribs of the old-style tube in the pics. Its a stock follower. Should be good with a Grams kit. Does appear to be stuck at the bottom of the ribs, follower still upright. Link to comment Share on other sites More sharing options...
jcc7x7 Posted July 8, 2017 Share Posted July 8, 2017 (edited) Helps to bevel the two vertical ribs at the bottom so it transitions better coming up from the bottom. "IT" being the follower, Also suggest a TTI or grams follower Edited July 8, 2017 by jcc7x7 Link to comment Share on other sites More sharing options...
Doc Neeley Posted July 8, 2017 Share Posted July 8, 2017 Atlas Arms has a youtube video on tuning new mags also. Easier watched than explained. Link to comment Share on other sites More sharing options...

This is the old style tube. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
10ring Posted July 8, 2017 Share Posted July 8, 2017 I don't know if this is related but a number of years ago I tried the +2 Dawson basepad and had trouble with the bottom rounds getting side by side with the follower when enough rounds were inserted to cause the follower and rounds to get below the ribs on the side of the mag. I was able to cure the problem by using the Arrendondo base pad insert. https://www.speedshooter.com/product_detail.cfm?id=AA10&n=Arredondo-Base-Pad-Inserts Link to comment Share on other sites More sharing options...
Glk21C Posted July 8, 2017 Share Posted July 8, 2017 Buy something like 10ring suggests or fix it like jcc7x7 says. Either way buying different springs and followers won't fix your problem, their suggestions will. Personally, I prefer to really fix the problem like jcc7x7 told you. Good luck.

Aircooled6racer Posted July 8, 2017 Share Posted July 8, 2017 Hello: OK you have the old style STI mags there. Use a Grams spring and follower with a Hardy steel spacer or the Shooters Connection steel spacer. That combo will work very well. I have also used a Dawson 9mm follower and a ISMI spring trimmed to fit the follower. Thanks, Eric Link to comment Share on other sites More sharing options...
