That seems reasonable to me.
My issue with the mag release, as I note above, is that the P365 is a small gun and I have large hands. So I can't reach the mag release with the end of my thumb easily to push the release in. With the extended mag release, i can use the side of my thumb. I can't do that with the factory release.
As I wrote above, I am new to semi autos so am investing in training. It did not realize my difficulty in activating the mag release until my instructor tried to reach me, among a bunch of other things, how to drop the mag and load a new one smoothly and quickly.
It may well prove to be the case that while the extended mag release is great for increasing my proficiency in changing mags during training, it does not make sense for me, for the reasons you suggest, when EDC'ing the P365.
To be sure, I have more confidence in the extended manual safety being the right solution for me for EDC than I do in the extended mag release. But I do want to train with it some more to see how it develops.
