The ISSF rule referred to (offhand I do not know the number, David L will quote it) shows a view of the grip from the rear not the side.scerir wrote:Found this rule. "Any ***upward*** curvature of the heel and/or thumb rest and/or a downward curvature of the side opposite the thumb is prohibited. The thumb rest must allow free upward movement of the thumb." In those pictures the curvature of the thumb rest is not "upward", imo.
What rule number is that? I must have missed it.Gerard wrote:In 10m AP there's a rule stating that the grip may not allow the thumb to bend down past 90°. Is this not the case in the sort of pistol competition where these pistols are used? Nice looking carving in any case.
Seems perhaps I was recalling the bit about 'downward curvature of the side opposite the thumb' being prohibited as meaning the thumb rest itself. What does this mean then? The part above the index finger? Or is it referring to the part of the thumb rest above and inside the thumb as being opposite? I find the wording of much of these rules confusing. Why not index such comments with numeric designations to accompany matching drawings, pointing to exactly what element they're describing?ISSF Rules wrote: rule 8.12
10m Air Pistol Grips: No part of the grip, frame or accessories may touch any part of the wrist. The heel rest must extend at an angle of not less than 90 degrees to the grip. This applies to the heel rest in front and behind the grip as well as on the sides.
a) Any upward curvature of the heel and/or thumb rest and/or a downward curvature of the side opposite the thumb is prohibited. The thumb rest must allow free upward movement of the thumb. The grip must not encircle the hand. Curved surfaces on the grips or frame, including the heel and/or thumb rest, in the longitudinal direction of the pistol are permitted.
b) 25m Pistol Grips: Note a) applies. In addition, the rear part of the frame or grip which rests on top of the hand between the thumb and the forefinger, must not be longer than 30 mm from the point where the grip first touches the top of the hand forward to the deepest part of the grip. The back (rear) part of the grip must be cut so that it angles upward from that point by not less than 45 degrees.
If you look at the 8.13 drawing posted above, the thumb side is on the left and the side opposite the thumb is on the right.Gerard wrote:

Yes, poor wording indeed!Gerard wrote: I find the wording of much of these rules confusing. Why not index such comments with numeric designations to accompany matching drawings, pointing to exactly what element they're describing?
Another "strange" position of the thumb (air pistol, Mauro Badaracchi)Tycho wrote: Wonder who studied whom, between Vito and Ralf Schumann, seems to be the same idea of positioning the hand and use the thumb.
Nothing strange. Hold you (empty) hand in it's natural relaxed position, close it as if to make a fist and your thumb points to the trigger or middle finger.scerir wrote:Another "strange" position of the thumb (air pistol, Mauro Badaracchi)
I'm inclined to think that unusual (maybe natural?) position of the thumb has something to do with the best control of the pistol. Here (see pic) Mauro Badaracchi and his free pistol. In this case (pic) the perfect control of the pistol is achieved easily because of the full wrap-around grip. Maybe.j-team wrote: Nothing strange.

You are right, in that picture he has the steadiest hold I've ever seen!!!scerir wrote: Here (see pic) Mauro Badaracchi and his free pistol. In this case (pic) the perfect control of the pistol...
