I have not seen the Sig P938 in the flesh yet but own a P238. A 9mm in the size of my P238 will be a little hard to handle unless you can get a better grip on the P938. You need a gun you feel comfortable shooting so will wait for more reports when they get the P938 out. I got the P238 as a dailly carry over my old service Colt 1911. Issued that gun built the same year I was born! How's that for Government cost savings on issue weapons.
