I have a P30 as my EDC and I have an HK45. I think the HK paddle release is a better design for an ambi mag release than the Glock Gen4 reversable mag release, which doesn't let you use older non Gen4 mags in a LH config Gen4 gun.
Regardless of whether the mag release is a button or paddle, if you train & practice with either you can adjust to either.
