The major mfn of dies will usually make their dies with the "proper crimp" built in. Of course you have to adjust it correctly. So as mentioned above, that would mean that revolver rounds get a roll crimp and auto pistol rounds will get a taper crimp.
But, there is also finesse involved (in the correct amount of adjustment). Getting that perfect COAL and crimp at the same time. Use of a "factory crimp die" has helped some folks. Anyway, be aware because, some folks have been known to over taper crimp so that it looks like a roll crimp. And/Or, under crimp a roll crimp so that it looks like a taper crimp.
I'll just say to crimp it "good enough" so that the bullet doesn't move when it's chambering (moving from the mag into the chamber). Also, make sure that the bullet doesn't move from recoil forces, while it's waiting it's turn to be fired.
Take caution because, over crimping can also lead to troubles with "over pressure situations."
