Is this pic showing left hand neutral or strong grip?
 

What do you think?

Is this left hand grip strong or neutral? I think's it's a little strong, but the author of this picture has said that this is a neutral grip.

It's hard to tell from that photo. In "my world" a neutral grip is when you can have a flat left wrist and the face is parallel to your left arm at the top of your swing.

I've seen this somewhere. Whatever your hands look like while they are naturally hanging is YOUR neutral. Some people see two knuckles, some see three and some see one. It just depends on your body what your neutral is.

Looking a bit more closely, the left thumb is in a 'slightly weak' position, while the back of the hand is turned into a 'slightly strong' position.

The position of the left thumb is one of the most overlooked areas of the grip, and one of the most critical. It should be approx at 2:30.

The right hand in this photo looks pretty good, in as much as you can see in the photo anyway. If anything is 'may' be very slightly weak, I'd have to see where the hands were relative to the body.

This is a strong single action grip. Though the left thumb is toward the top of the shaft which is indicative of a weak single action grip, the #2 pressure point is on plane which will support impact and therefore qualifies as a strong single action after all is said and done. The #3 pressure point looks in good position on the aft side of the shaft but the right wrist apears to be a bit low. This might be due to the reduced #3 accumulator angle.

This doesn’t seem to be the kind of grip that results from taking the grip at impact fix location and getting the wedges set.

I could be completely wrong.

Furthermore, where in the book does HK use the term "neutral" grip?:)

Hard to really say from the picture orientation but it looks like the handle runs up the left hand lifeline and passes under the thumb pad, rather than nestles under the heel pad.

Also, the right forearm seems to be above the left, rather than under it.

All in all, the left hand appears to be strong whilst the right appears to be weak.

Back to the drawing board i.m.h.o.

I'm going with Turned Left Hand on this one due to the position of the left forearm. It's not vertical. If the dude had on a watch you could see the watch face. Another good check is if your hand is vertical you should be able to see the WHOLE grip cap. If the Left Hand is Turned you will not be able to see all or any of the grip cap because your forearm will be blocking it from view.

What we really need to see here (in this Top Down view) is a Strong Single Action Grip with the Wrists in both Impact Fix and Adjusted Address conditions. Anybody?
