I bought my 1911 Dan Wesson Specialist used and recently took it down for cleaning etc, and noticed some marks on the frame and recoil spring guide. Can anyone look at this picture and tell me if it looks like their Specialist? The marks on the rear of the guide match marks in the frame where it rides. I’m worried it is beating itself to death. I know nothing about the gun. I did replace the recoil spring and the firing pin spring today. The recoil spring is a 18.5lb now. I will have to order a new mainspring for it. It should be a 23lb correct?
