Nice work Mitch,Glad to see you finally got it in your hands.What are the silver circles around the charge holes? Looking at my TL(non target) and they are not there.
To me, one of the most desirable models S&W ever made. You have a REALLY nice one! Congratulations, Good Shooting!
Certainly no expert, but it appears the charge holes have been chamfered for ease of loading.
See the seam between where the 'white' circles meet the extractor star prongs; they are flush, no chamfer.
My TL chamber mouths look just like that, it's just blue wear from the case rims when fired.
