Three months ago I purchased a new Glock 30 Gen 4 and to date I have shot 900 rounds. Before I bought the gun I shot a rental Glock 30 Gen 3 two times to make sure that I wanted to buy the 30.
I am a left handed shooter and my question is about the grip with my left hand. When firing the gun I am trying to decide the best position for my pinky finger. I have tried to squeeze the grip mostly with my second and third fingers and let my pinky lay against the front of the mag with no squeezing pressure from my pinky. I have found that when also squeezing with my pinky it tends to move the gun. I have also tried to squeeze the grip mostly with my second and third fingers and let my pinky curl under the bottom of the mag. When shooting, consistency is very important and I am constantly switching back and forth trying to figure out where to put my pinky.
My target accuracy at the range appears to be pretty much the same regardless of where I place pinky.
I am using the OEM Glock 10 round mags. I have also tried the Pearce PG-30 grip extension (no additional rounds) and have removed them from the mags. With the Pearce extension I would try to completely place my pinky in the pinky finger groove which made my index finger press against the trigger guard resulting in Glock knuckle when firing the gun.
With the above information do any Glock 30 owners/shooters have suggestions about the proper or best strong hand pinky finger placement?
