There is no basic rule. As an example when I shoot target (.22 and 10m air Olympic) the grip is just enough to hold the gun, my main objective is trigger control and sights, in fact I can feel the recoil of the .22 ... but then there is no 'hurry' to engage the next target.

When shooting IPSC is a complete different matter, my grip is very tight, in fact the left hand does most of the grip while the right hand controls the gun, about 60% left, 40% right (of course switch if you are lefty), the main objective is to control the recoil and engage the next target as soon and accurate as possible.

Probably for recreational shooting will be a happy medium .. Brian Enos book(s) are very good.
