STI 2011 126mm 9mm Magazine Springs

[45 Raven]

What is the source for preferred replacement springs for STI 2011 stock 126 mm (9mm) magazines?

Only using 17 rounds in the magazines, with no special needs, but they have quite a few miles on them.

While replacing springs, is there anything else you would recommend be done?

Thanks.

If the factory ones always worked for you why not just get those?

I planned on just purchasing standard STI springs, unless someone has some compelling advice on a better plan. I fully understand this isn't rocket science . . . . just leaning on experience to see if there is a "better mousetrap" before proceeding.

if your not looking to get extra rounds in the mag just replace with factory springs and followers.
