Suggestions to improve my grip?
For some reason, my left hand won't stay put when I shoot my Ruger 345. My right hand is fine (I am right-handed) but when I shoot (particularly if I am shooting rapidly) my left hand tends to shift position a little on me when I shoot 2-handed.
This causes me to either re-grip with the left hand (costing me time) or I go ahead and shoot with my left hand in different positions (affecting accuracy).
I don't seem to have this problem with other guns. It just seems that the gun seems to "jump" to the rear of my left hand so my left hand seems to slide toward the front of the gun. My right hand has the grip in the center of the web of my right hand so it's fine
I have "typical" strength in my hands and have tried gripping the gun more strongly with the left hand but still have the problem.
If it helps, I grip the gun in my right hand, then place the left hand against the left side (to fill in the gap where my right hand isn't). The thumbs are parallel and pointing toward the front of the gun.
Any ideas? (I do not want to change guns.)
