Their specs are +/- 5 degrees. If it's in that range it is 'in spec'. I think I could eyeball better than that. Of course it would be too expensive to put an indexing mark on the frame and barrel. I'm glad to hear of a lot of NON canted barrels. It seemed like an epidemic. I'm not knocking S&W either but if a quality gun manufacturer can't screw a barrel on straight, something is definitely WRONG!
