I just adopted the "baby" of the SIG pistol family, a P938, which is SAO, built on a 1911-style action, and is carried "cocked & locked". It is chambered in 9mm, and carries 7+1 in a single-stack magazine. Empty weight is only 16 ounces. I was able to put 23 out of 25 rounds in a 10" circle at 18' right after I bought it. It will be a good backup gun if I choose to start carrying a backup to my primary EDC.
