as far as my fingers getting a little beat up on the trigger, go to Home Depot or Lowes and buy a cheap set of rubber gripping gloves for about $10.00-15.00. Make palms and finger pads are sturdy, Glass handlers gloves work best for me, with mesh on the upper portion and nitrile material on the palms. I buy them one size too small as not to have extra material that might be stuck inside the wrong place at the wrong time. These gloves protect against rubbing and chafing inside the trigger guard.
I recently bought trigger shoes for my matching Kel-Tec P-11s. For those who don't know, trigger shoes widen the surface of the trigger to make it easier to place your finger on it. Make sure you use a heavy-duty glue (Liquid Nails, Gorilla Glue, or epoxy) to glue the shoe onto the trigger before the set screws are set into their place.
I'm guessing that there will be a trigger shoe available soon for the Ruger LCP, as well.
