Julie Golob explaining how to hold a handgun.

She's never once had surgery for carpal tunnel or to have a badly dislocated thumb tacked back on.

Nor have countless other pistol instructors.

Thumbs forward isn't the strongest grip anymore if you've had these surgeries.

Worse, if you've had your thumb relocated, thumbs forward means twitch to the strong side as the sear breaks.  Ask me how I know.

I'd mentioned fighting with the M&P and getting the gun to group where I was pointing it.  It took a conversation with my doctor about it to figure out that I am now "deformed" and my right thumb is just tied into my index finger's flexors forever now.

She mentioned that it's also common for carpel tunnel people to get this problem once that ligament is "released".

We've got to hook our strong side thumb to basically pre-flex the twitch before moving our trigger finger.

Everything she writes in her article is true, and if you've avoided surgery, should work for you.  But if you have, and it isn't, try my way on top of her advice and see if you don't see some improvement.

UPDATE:

Crude approximation of what Ms Golob and many instructors are teaching (I can't do it correctly because broken-and-fixed thumb).

What I changed over to that fixed the twitch.

While it's not perfect, or stylish, it does overcome my injuries and their aftermath.
