Not sure if these work
Posted by Rodel Ibus on Jun 5th 2018
Before I bought these springs for my STI mags I asked customer service if these would work with my stock followers. Customer service said the stock follower will work with their springs. With this said I did not order the TTI SV/ST universal follower. Well apparently they don’t work with the stock follower as customer service said. So remember to order the TTI follower if you own an STI.
Good springs but shipping too expensive.

I like the Taran spring, follower, baseplate set up for my 2011 but they need to offer a better deal in shipping. 3 9 dollar spings and $10.00 shipping...
Easily a Go-To for STI Mag enhancements

They do what they're advertised to do, and do it well. They last long enough to be worth the cost and are dependable, especially on match-days.
