Any are too many.

I am sorry - I just find the slab sided barrel to be an abomination. It is revolting.

Its contours do not match the frame. Remember when S&W took so much care to match its barrel contours to the frame that it would bevel the frame edges on the Combat Masterpiece so that the frame would match with the tapered barrel? Now, it just doesn't seem to matter. Barrels with every conceivable profile are just screwed on the frames.

To my admittedly old eyes, these new performance center profile guns are just wrong.
