I think if you are used to a shotgun bead the learning curve may not be that bad. But for many, it will require re-training away from concepts that center on FRONT SIGHT acquisition. May be a cool idea, but may also be the odd nail sticking up in the board.
But I detest the porting. It’s a 9mm, after all, and I can’t see how a reasonably capable shooter would benefit from it. I think it’s a gimmick that will be more trouble than it’s worth in extra cleaning.
I handled one but decided to go for one of the other P365 varieties.
