My last Traditions SideLock, had a chomed barrel and the difference is fairly stark. When they talk about a bore being bright and shiney, these are a mirror finish. I find that they clean up easier and easier to load. I still don't trust letting any barrel sit, after firings but would not be surprised if these bore are more forgiving. I'll bet if you contact teh factory, they could give you greater detail. ....
Be Safe !!!
