Thanks for the Post! Last night, I ordered 5 of the +4 Followers, 5 New Mag Springs (That work with the New +4 Follower...), CW Upgrade Kit (SS Guide Rod, Power Spring, Bushing, & Plunger...).
I opted not to pay the $19'ish for the Mag Buttplate per Mag, to add 1 more Round, when I could order another 10 Round Mag for a few $$$ more.
I'm good with 14 Round Mags for now, until something Less Expensive comes along.
