Yep exactly, yes the shorty is lighter, if that’s what you are worried about transition wise, but not to the point, in my opinion, to make you any better.
Im sure some do like it over full size guns, but that’s the nice thing about open, it’s all personal preference. I was lucky where I was able to try out a full size gun from a friend compared to my shorty. I think you’ll enjoy shooting the full sized gun more
