This is a great topic, and I want to post more on it later.
This may sound weird but I was experiencing this and I found that I needed to keep the oil and sweat off my hands. I was shooting at a range with poor AC and after I started to sweat a little bit my non shooting hand was slipping off my shooting hand. I was using my shirt to wipe off both hands.
Now I make sure I wash my hands thouroughly before going shoting and I bring some alcohol wipes with me and a towel. If my hands are getting oily (not from gun oil but just from my skin secreting oil) I wipe them down with an alcohol towellete and then dry with a towel.
