I don't think the factory pads really stick out from the magwell as much as I'd like for positive insertion/removal.
I was looking specifically at the CZC extended pads but they had a note that in 9mm you don't get extra capacity.
Looking around google results it seems plenty of other people say otherwise and I see no other extended base pads for the TS mag sold with that same disclaimer.
What's the real deal? Without changing the guts do you get what, 22 or 23 rounds?
