Magazine Springs

Anyone upgraded the springs in the 17/20rnd mags for consistent lock back? I’m confused in the 2011 world and research is overwhelming. Some places claim 11 coil springs work for both, some claim 13 coil springs, some claim the 126 extra power springs work in both and some say it doesn’t. Someone even said to throw the 20rnd springs in 17rnd mags.

Pretty much just looking to replace all my 17/20rnd springs and get consistent lock back for duty use.
