For me, I had it narrowed down to the Glock 21SF and the Custom Colt 1911 70 series.
In the end, I would rather have the 1911 with a commander hammer and GS. I would also add a Wilson single sided tactical safety, but narrowed and shortened some. To me, this is the ideal CCW, except maybe a CCO type gun.
The Glock is super in most ways, but hard to CCW.
