Miller is absolutely right. Just because both barrels goes down does not mean both locks cock. Each side has it's own cocking mechanism.

I bought a S x S several years ago and found that it was not recocking the left barrel every time. An adjustment had to be made to the cocking mechanism. It can happen to most any doublegun, and is no indicator of overall quality, IMO.

This is a job for a good doublegun smith.
