If James is unable to help you, there is a possible alternative, contact a local range and talk with one of their experts if they have one. I would not bring the gun to him due to the situation of course, but they might see their way to coming to you if they are not too far away.
Another, perhaps more radical solution, by some people's thinking, might be to call the local le at their range if you can obtain their number (you might try to get the number for their academy as the range probably will be there). As long as you are legal and I presume you are, you shouldn't have any problem with the police once you are specific in your explanation and put the weapon exactly where they tell you to for officer safety prior to their arrival. They will probably send out one of their rangepeople, armorers, etc. to take care of the problem. I believe they will be quite eager to assist you in ending the problem so no one gets hurt. Since no crime has been committed, only a malfunctioning gun, you would have nothing to worry about.
Tho I am embarrassed to admit this, I had an incident a few days ago with a weapon I have owned for years. The malfunction was mine, not the gun. Yes, I am retired le, but I honestly believe it wouldn't have made a difference in the outcome. A SWAT Sgt. came and was able to get the rounds out of the stuck cyclinder. He probably told the story at briefing and all had a good laugh. I had a safe gun.
Let us know what happens please. Good luck.
