Well, I had the opportunity to ask several veteran North Carolina Highway Patrol officers what they thought about 357 Sig. The official sidearm cartridge for them is currently the 40 S&W which they both said was a good cartridge. At one time, however, they were issued 357 Sig and, to this day, they much prefer it since the 40 S&W sometimes bounces off of windshields whereas the 357 Sig penetrates right through.

For competition USPSA shooters, however, the 357 Sig offers no advantages as was detailed in some earlier posts.
