60% weak hand, 40% strong hand, right?
70% weak hand, 30% strong hand?
80% of the available strength in your weak hand?
I honestly don’t know. I’ve heard all of these things from big name instructors over the years and I’m not sure any of them are really right. I’ve been playing around with my grip a lot lately and I’ve basically come to one conclusion:
Grip as hard as you can with your strong hand without disturbing your trigger pull (which probably isn’t all that hard) and then grip as hard as you can with your weak hand. This seems to give me the best results.
I’m not sure the ratio from strong hand to weak hand is really important, the most important thing is gripping hard. You could grip the gun 60% weak hand and 40% strong hand and still be holding it daintily, and that’s not going to get you anywhere.
To put it in perspective, when I’m dryfiring and really focusing on the grip I’m gripping so hard that I need to take a break for a 7 or 8 minutes and browse Facebook and Instagram until my weak hand feels normal again. It seems to be giving me the most actual shooting results over anything else I’ve tried in years.
Here’s the other thing: I don’t feel like I need a grip strengther thing to squeeze on all the time, as I’m physically strong enough to grip the gun really hard, I just need to train myself to do it all the time.
Your mileage may vary, but don’t be afraid to try new things and do away with the conventional wisdom. A lot of it isn’t wise.
