How tight should the grip be ?
Like I said I will see someone about the grip shortly but I can try some small (non permanent) modifications at home in between times.

Rob,
This is a tough question that I have been wondering about also. For one thing, hand size (volume) varies during the day and from day to day. Weather can have a big effect on this. While this problem is most evident with a FP grip, it is a factor with any anatomical grip. I don't like the idea of continually readjusting the palm shelf to compensate, so I have a couple of rules-of-thumb (rules-of-palm??) that I use. I am throwing them out for discussion, and hope to be enlightened by the responses.
First, I feel the grip needs to be shaped so that whatever pressure your hand exerts on it is almost entirely front to back, i.e. no lateral pressures. This needs to be true even when you (inadvertently) make slight changes in grip pressure - these should not cause lateral movement.
Second, you should be able to apply front to back pressure without feeling a lot of upwards pressure from the palm shelf. If the palm shelf is too tight, then an inadvertent increase in gripping pressure will cause the hand thickness to increase slightly, which will exert a downwards force on the palm shelf, i.e. on the right side of the grip (for right-handers), again a lateral pressure. And the palm shelf adjustment needs to be made when your hand is at its largest volume, unless you want to constantly be readjusting it as your hand size changes.
Third, the palm shelf angle (front to back) is important. I like to adjust the angle so that whatever pressure is exerted by the palm shelf exists along the entire length of the hand, not just at the rear or front. This may require some shaping of the palm shelf, which (on AP, SP, CF or RF) can only be done front to back, not side to side.
All the above pertains to grip fit, but of course there is also the issue of having the gun point properly for you. On some guns (e.g. Steyr) you can adjust the fit, and then deal with the pointability by using the built-in adjustment screws. On others (e.g. Morini electronic), you need to consider pointability as part of the grip fit equation.
The final step, as Don Nygord advocated, is to move the trigger so that it is in the optimal position for a smooth straight-back pull. This, of course, assumes your gun has an adjustable trigger blade. If not, then all the above is even more complicated.
I have done a lot of grip work and gradually come up with these concepts, and they are continually evolving - I am not claiming to have any answers here. But, to get back to your original post, I would suggest that you just go ahead and work on your own grips, because that's how you learn. Almost nothing you do will be "permanent", as long as you have access to putty (and don't care what your grip looks like).
HTH,
