Magpul Magwell & Compatabilities

I recently added Magpul magwells to a couple of my Glocks and am curious about fitment of the various aftermarket mag extensions. Specifically looking to add 2-3 rounds to a Glock 19 but not have issues with the magwell. Anyone know of a chart or review that lists mag extensions that work? I OEM +2 will work and Arredondo +3 apparently won't...
