I bought my girlfriend a SIG P320 for Christmas which she used this past weekend for Predator Security & Defense's Fundamentals of Combat Pistol Course. Other than checking the sights and getting basic familiarity with the pistol, this was my gf's first major test with it. I might need to get her a smaller frame but overall she really likes it and and it ran perfectly during the 300+ round course. I used my P239 which has never hiccuped in thousands of rounds and the only issue I had was riding the slide stop due to shooting way more 1911s over the past six years. 
I want to give a shout out to an excellent group of trainers at PSD. They really focus on military applications and their experience and competence is evident from the get go, which is not surprising given their backgrounds as SEALs and Green Berets. They did a great job of passing on their knowledge and experience with excellent drills throughout the day presented in an enjoyable but intense way. I hoped I would learn a thing or two but came away with much more than that. We plan on attending more courses with them in the future, hopefully when it's warmer than 20°F. I plan on buying my own P320 for future courses.
