The security 9, is considered a midsize, so smaller and lighter than a 1911, and probably easier to concealed carry, although that's not a big concern right now. Basically just want it for home defense, and recreational shooting.
I did watch a few youtube reviews and looks like a good choice to me. Simple to shoot, simple to breakdown, no fancy bells and whistles.
Years ago I tried shooting a friends 1911. To me it seemed big and heavy, and I couldn't seem to hit the broad side of a barn with it....
