I was impressed by the knowledge here. Love my Slim. but initially had some feed problems. that have seemed to have solved them selves since I go to the range and put about 100 rounds through it almost 2 times a month. am a little concerned about the trigger pull on it I bought it used but doubt if it had even been fired wasn't even a single scratch on the mag. Read on one of the threads about the firing pin length. so this will be what I look at next.
