You can dry fire a Darne to your hearts content as well, Stan. The guys at the shop in St. Etienne put them away in the rack after they snapped the triggers.
You should have the barrels in place when you do that. I can’t understand why people would dry fire a double gun without the barrels in place, but, there it is.

It was an English gun, Stan. Other than that little detail, it was well finished and quite nice. I believe the ‘Smith actually shortened the discs up, and reused them, after fitting them correctly.

Best,
