The last step in the exercise is to fire while doing everything incorrectly. Whatever you found that worked best, do it incorrectly. Bend your arm so the gun is not well supported, shift your weight back on your heels, fire the gun when it's not aligned vertically.

Many shooters mock anyone on the range holding a gun in the so-called "gangsta" style, with the gun positioned horizontally. But, in reality, bullets don't know or care whether or not the handgun is held "funny." If this is the hold you are forced to use when firing in an unconventional position, you need to learn to get hits with it.

Now you'll know what to expect in the worst case, while keeping in mind that a hit, however poorly placed, is better than a miss. And at the same time, instead of waiting to make the "perfect" shot, you won't hesitate to fire.

Most likely your handgun will malfunction while doing some of these drills. A better grip cures some malfunctions, but others just happen. Not the fault of the gun or you. Stuff happens. Fix it and get the gun running again as quickly as possible.

As far as using sights, to me this is a non-issue. You'll use as much sight or not as you need to or can get from the various odd shooting positions. The point is, you'll know what to expect.

Learn to handle your gun in non-standard, non-ordinary conditions until those conditions become standard and ordinary.
