The first thing you need to do when taking the 50 yard shot is ignore the voice in your head saying you can't shoot a handgun 50 yards. When I went to the Pro-Am a few years back there was a 60 yard shot. Actually, four poppers at 60 yards. One day I did it in four shots and the second day it took me five.
If you practice with your handguns in different settings and situations, the 50 yard shot is a cake walk.
