I'm curious on the nitride treatment. One of the selling points is that it will add "hundreds of feet per second" to you rifle. Did you notice any difference?
While Black Nitride treatment certainly improves the bore surface, someone is feeding you crock of baloney with that claim. Black Nitride has much to recommend it, without resorting to such foolishness. I’m sold on it:
Only the slide was treated.
Barreled frame, cylinder, crane, side plate and thumb piece were treated.
Barrel, receiver, hammer, breechblock, lever, trigger and all screws were treated. I couldn’t tell for sure whether the 5 hits on the pictured target were 4 and 1 or 3 and 2 @ 50 yards.
