I started carrying a level 3 Raptor for my Glock 22. The only problem I had was, when shooting in wet weather or when my hands were sweaty, my finger would slip off the finger release. To fix this without spending a lot of money, I took a small piece of non-slip safety tape and cut it down to fit the button. Now no matter how wet my fingers are, they don't slip. If you cut it just right it looks like it belongs there.
