I recently picked up a T/C Encore, not a Pro-Hunter, and as i was looking at it i realized that it has a swinging hammer. I thought that this was something that was only on the pro-hunter. is it?
It could have been a conversion as Pahoo said or it could have been sold originally as a pro-hunter and then the owner replaced the pro-hunter stock/forearm with a standard version. The only difference between the pro-hunter frame and the standard frame is that swing hammer.
