Can't help you with a 9, but if you ever decide to step up to fo-tay-fi, I can tell you it is a nice gun. I got one about 2 months ago and it is tight.
I wanted to make it tighter so I got an oversized barrel bushing and fit it. Then I got an oversized slide stop pin and it was a drop in. Last I installed an extended extractor that sent ejected rounds off in a better direction.
That gun is a accurate as my custom made target 45 with my cast reloads.
A 9 would be a great addition to the JSOC line.
