I use COlt mags with green followers and 'red" SAW springs. I also have a bunch of older HK mags. At some point when I need new mags, I will probably try the CP mags, as I have heard nothing but good things about them.
I use Magpul gen 2 followers on all my USGI mags and only loads them to 28 rounds for ease of tactical reloads on a closed bolt.
For my most used mags I also use Wolff extra power springs and Magpul Ranger or L-Plates.
I also have C Products SS mags which are easier for tactical reloads even if they’re fully loaded with 30 rounds, they are a little wider internally which makes their stack height lower.
HK mags are nice but I only have one because they’re expensive and I prefer the C Products SS mags.
I heard that C Products are going to offer Teflon finish of their aluminum and SS mags soon.
I have the new Cproducts SS mags with the Teflon finish in stock so they are out.

Which springs do you guys run in your you C-Products SS mags? The CS spring or the SS spring?
Also is there any difference between the Grey and Orange follower besided color?
Cproducts mags come from the factory with a CS spring or a SS spring (you can choose either). I would go with the CS spring as it is a superior spring to the SS one.
There is no difference between the followers (other than color).
In the mags that I build, I ONLY use ISMI CS springs.

So when I order from your site, which spring do the mags come with?
I only order my Cproducts mags with the CS springs.
