I have several j-frames and none have the problem you describe. I also have a BG38 and the cylinder latches just as easily (if not a little better) than the others. In fact, when I first bought the gun I noticed how smoothly and securely it latched. I don't think this is caused by the gun being plastic nor do I think it is a problem that customer service should ignore. I would keep calling until you get someone who will help you.
