Thanks for the reply. The release on this one, and on my Uberti, is the same. It is a spring loaded cross pin where the right side screws into the left side. On my Uberti it functions flawlessly, but on the Navy Arms, the pin has the tendency to pop out during shooting...pita!
Are you saying the Navy Arms revolver was made by Uberti? Upon close examination, there is very little difference between my Uberti and this NA revolver, and all of the little details are the same.
