I just took my new gen3 G19 to the range for the first time. This was also the first time I ever shot a Glock. Gun functioned flawlessly with WW box 115grs. But here's how I shot. My first shot after inserting a loaded magazine would be a couple inches directly above the POA. All the rest of the shots formed a 4" group about 6" to the left of POA. I shot 2 mags loaded with 6 shots each so I ended up with two holes right above POA and a ten shot group to the left. I was shooting at 25 yards, two handed, wrists on sandbags. Only thing I can think of is my finger is on the trigger different for my first shot and then I shift it somehow. You guys with long fingers, where does the trigger contact your finger? I think I'm going to have to pull with the trigger all the way up to the finger joint.
