I'm familiar with many of the grip techniques and recoil management techniques taught right now. There is no doubt in their effectiveness and that people are getting really good results with them. However, a very significant portion of them, perhaps all (?), seem to rely on a very high degree of grip tension/strength. There appears to be some variance in the amount of shoulder/elbow/body tension. There seems to be some variance in the way that people describe recoil management, with a strong segment focusing on relaxing tension and "letting it recoil" in some respects, whereas others have a much more aggressive approach.
For me, there are a number of factors that are encouraging me to try to reduce the overall tension in my shooting technique, which can include long term health, fatigue, mobility, as well as mental effects.
I'm having a hard time finding *any* handgun grip techniques that are explicitly or intentionally designed to allow for minimal amounts of grip tension, except for precision Olympic style target shooting (I'm looking for something more directly applicable to defensive handgun applications). Do they exist? I've found recoil management techniques that begin to approach that, but they also involve a grip that, more or less, needs or wants to be tighter and stronger.
Essentially, I guess the big overall question is, how do I grip the pistol and manage recoil in such a manner that allows me to remove or reduce as much tension and "muscle use" from the shooting process as possible? I'm open to either two or one handed approaches (both in a single "approach" are welcome).
Many people, probably most, here have more experience than I do with this sort of thing, so I'm hoping someone can point me in the right direction or just lay the answer right in my lazy lap.
