If you're doing it for self defense, don't change anything except for sights.
If you're doing it for sport and you or the lives of your family and friends aren't at risk, then fine.
Just remember to test the firearm with whatever load you want to carry. You may find a point where the rate of misfires is not acceptable. On the other hand, you may not have any misfires at all. Just test the modified gun with the ammunition. That's the best thing to do.
