I was listening to a John McPhee "Sheriff of Baghdad" Podcast and he very briefly mentioned using push/pull recoil control. This got me to thinking about it and apparently I've gotten away from creating much of the push/pull isometric tension in my grip. I think I started focusing more on camming my left wrist forward while gripping the gun high and hard vs. actually using my support hand as an abutment for my shooting hand. I should mention that I'm not a very high level shooter by PF standards and I have pretty limited training compared to many here.
Anyway, I went out and shot a few rounds concentrating on building more push/pull tension. My sights felt like they were tracking better than normal and I felt more accurate at speed, even out to 10-15 yards. The speed at which I could keep roughly fist sized groups at 10ish yards was particularly gratifying, although I didn't have a timer and I don't keep track of such things well to begin with. Perhaps it was even helping my trigger control, or lack thereof.
I'm hoping to get thoughts from some better shooters about how you use(or don't use) that push/pull isometric tension in your grip/stance. I've noticed that when talking about nuanced things like grip pressure, tension, force direction etc., the terminology can mean different things to different people. Sometimes people seem to use very disparate language, while trying to explain the same concept. Or the opposite, where they are using the same words, but driving at very different meanings. For this reason, I hope everyone can try to be somewhat specific if you get into one of those gray areas.
I'm really curious to see what different people think on this topic.
