Any capacity penalty for MBX +20% springs?

Wouldn't mind a little more oomph to the mag springs. Do I lose a round of capacity? I use a maglula and am running the 24 round 9mm 140's.

There is always a chance of failure when you go for mag capacity vs reliability.  This is the whole reason for my post about MBX vs Atlas.......

In 40, my capacity remained the same but I could not reload into them reliably. I have mags with the +20% that only see 20 rounds and some with the original springs that get 21 when needed.

I put one in a mag for a season to compare it to my other regularly sprung MBX's. Turned out to be my most reliable mag and became my make ready mag, no loss in capacity either (21+1 .40 cal)
