I just came from the range with my new Sf.. It’s not the sfx, but if your looking for a great gun I would grab it. Just put 400 round through it and had 1 error because my magazine was not looking enough for the magwell. Also a little snappy with the 114 grain, but super smooth with 147. Also tan 114 jhp pretty well. I will be buying another one when my 30 days are up. Hope this helped.
