might be a 1 in a 1000 chance for a button release, but you have zero chance of accidentally dropping a mag on a paddle release.
You also don't shift your grip to release a paddle.
These two reasons are exactly why I find the paddle release to be the superior system.
I find it dissapointing that Walther has dropped this feature from the PPQ.
I was truly considering a PPQ to go along with my P99AS, but the mag realease change (plus the more important fact that mags are no longer compatible) has really tuned me off.
