I can't shoot it without first chambering a bb which is where I'm having the problem. As for the safety the gun doesn't seem to have one, I've been looking for it but to no avail.
If you can, Try pulling the slide back and putting a BB in manually, and then closing the slide. If you can fire it after that, then there's a probably a problem with the plastic piece on the slide that pushes the BBs into the tube.
Also, did you read the enclosed instruction book, or is it functioning as a new coaster?
