Grip tape ordered, because it can't hurt, but still the problem is my front fingers sliding against my dominant hand fingers. One of the guys that is usually at our weekly practice matches uses grip lotion, so he will likely let me try some.
I was thinking, when I use to do a push/pull grip, I didn't have this problem (but I also wasn't shooting compatition). Is the grip more forward/back, or fingers pulling towards your palm?
