Lots of ways to skin that cat. Random thoughts..... There are several female grand master class pistol shooters, that can't even begin to match the grip strength of a 15 year old boy in fair shape, that can shoot just as fast and as accurately as the guys that work on their crushing grip with the heaviest of grip exercises.
The more you crush your grip onto things the less fine finger motion you have.
There are an equal amount of fast, accurate pistol shooters that advocate neutral grip tension and let the pistol recoil as long as it returns to the same point each time.
Still others that recommend about a handshake firm grip with a bit of push pull to tame recoil.
What Jerry does works for Jerry, and it's as good a place to start or try as any, but it may not work for you and how you interface with a pistol.
Best way to see what is working for you is a drill from long ago called a Bill drill*. From the holster draw and fire 6 shots into a target 7 yards away within a 2 second time frame. If all the shots are centered and within 6" of each other your " recoil control" is working what ever you are doing. If not change things until it is. Warning! This isn't a drill to practice over and over! It is a drill to do every once in a while. Kinda like a check up.
*Bill drill, named after Bill Wilson of Wilson Combat fame
