I looked into the .40 Super and even talked to the gent that is making the barrels. It is a hot round buttttttttttt the current laod data has been cut way back from the original. Slide velocity without a comp would quickly become a issue which is probably why the newer data is backed off. he did tell me that he has a personal gun set up with Dawson sights like mine in .40 super that would consistently shoot 3" groups at 100 yards. After weighing all the options I felt like the .460 was a better fit for me. reflex264
