A primary and backup gun perhaps? Shown here are the Beretta 92FS and Beretta 3031 Tomcat.
The Beretta 92FS is a full size 9mm with 15+1 capacity and perhaps the most comfortable to shoot 9mm I own. The Tomcat is a .32 ACP pocket gun with a unique tip-up barrel design. While you can rack the slide to chamber a round, you don’t need to. Just insert a loaded magazine, flip the barrel release and it will open, exposing the chamber. Drop in a round and you’re good to go. Couldn’t be simpler. You can read more about the Tomcat here.
