Mike62 Posted November 12, 2021 Share Posted November 12, 2021 I have 4 Gen1 STI 140mm magazines. I wanted to add basepads for additional capacity. Is there a recomended combination of base pad, follower and spring? Appreciate any insight. Link to comment Share on other sites More sharing options...
ARac40 Posted November 13, 2021 Share Posted November 13, 2021 (edited) TTI 4mm base pads with grams springs & followers seems to be the norm. That’s gets you 20 reloadable in a .40 prolly 23-24 in a 9mm. Good luck. Edited November 13, 2021 by ARac40 Link to comment Share on other sites More sharing options...
Mike62 Posted November 14, 2021 Author Share Posted November 14, 2021 Thanks for the advise. I have been trying to decide between the dawson vs. the TTI. I like the idea of easily being able to take them apart but it seems many folks prefer the TTI. Is there a paticular reason? Thanks! Link to comment Share on other sites More sharing options...
Jim Watson Posted November 14, 2021 Share Posted November 14, 2021 I got TTI because of its retaining pin. Does Dawson have positive retention? I can't tell from their ads and I was tired of factory floor plates popping off when dropped. Link to comment Share on other sites More sharing options...
ARac40 Posted November 14, 2021 Share Posted November 14, 2021 Personally, I don’t think you can go wrong with either option for a 2011. Big thing between TTI and Dawson is size. They are both easy to disassemble and work on without tools. Link to comment Share on other sites More sharing options...
sauza45 Posted November 15, 2021 Share Posted November 15, 2021 Depends on what style magwell you have. Dawson does not work well with the cheely grip/magwell. The TTI will work with any magwell. Link to comment Share on other sites More sharing options...
cbrussell Posted November 15, 2021 Share Posted November 15, 2021 “sauza45” hit the nail on the head. I used the Dawson with great success until I changed to the Limcat magwell; then I had to change to the TTI 4mm. Link to comment Share on other sites More sharing options...
