A picture of the actual jam would have been helpful...a picture of just your gun is not likely to lead to a solution.
Is this a used or new gun that you just bought? Has it worked in the past? Have you or anyone else done any "work" on it?
Sometimes you get what you pay for, sometimes you only pay more for what you get.
Three shots are not a "group"...they are a "few".
