40+ years ago, . . . I was taught to learn my "grip", . . . how the weapon should "feel" in my hand, . . . so I would know immediately if I did or did not have it right.
Lesson 2 was how to get that proper grip, . . . and it works for "most" people.
Stand you shooting elbow on a table, . . . with your forearm pointing 90 deg straight up.
Pick up the auto loader in the non shooting hand, . . . form a "V" with the thumb and forefinger of the shooting hand, . . . lay the firearm down into that "V" so it points dead straight up from the bones of the shooter's arm.
Holding the weapon yet with the non shooting hand, . . . begin by first wrapping the pinky finger onto the grip, . . . then the ring finger, . . . then the middle finger. If you do it right, . . . the middle finger should fall under the trigger guard and force the other two down just a tad.
Pull the thumb around towards the trigger, . . . under the safety.
Extend trigger finger along side the slide until it is needed.
This is how I was taught in Uncle Sam's Canoe Club, . . . and it has worked for basically 40+ years, . . . YMMV.
May God bless,
If you can breathe, . . . thank God!
If you can read, . . . thank a teacher!
