Been in the works for awhile but finally introduced to public. Initial reports are that it is a refined FNS which is a great gun and highly underrated. I, personally am looking forward to trying one out. It and the CZ P10. I know a lot of folks like to hate on FN and some things are warranted (Hard to get parts, accessory availability, cost of mags), similar to HK, but the engineering and quality can't be denied.
