If you google MP 9 low and left, lots of threads on it. Most cases it the guy pulling the trigger. It was for me, with about 800 or so down the pipe I've almost mastered the beast. I think I my case it is the trigger, say good bye to MP trigger and hello Mr Apex trigger kit. It's going in tomorrow. Don't give up on it, they really are nice guns with bad triggers. My 2 cents.
