Anyone know if there's a difference between the barrel with one and the one with two dimples? My 9FS is new (Sept 2013) and has one dimple. I just shot it for the first time today. I liked it. I have to get used to the trigger. I shoot my Shield better, but I've had it for a year longer and have different sights on it. I wasn't checking group size because we were just shooting a 12x12 steel plate. I definitely could've shot better, but it was probably not the gun. I'm getting used to the trigger, which is a little different than my Shield.
