You need both, point shooting and sighted shooting.

If you are going to practice point shooting, do it with one hand, if you have time to get your support hand on the pistol, you have time to get to the sights.

You don't need a gun to practice point shooting, use your index finger. A little trick to help in practicing point shooting is to extend your thumb along your index finger while you do it. After all that's where the thumb normally goes with a pistol/revolver, extended to the side of the gun.

Point shooting is faster for short ranges, so is finger pointing. Just stab your target with your finger. Stab where you want to shoot. Back up a bit and keep doing it. As you back up to where you have difficultly, then use the split second to use your sights.

I'm still a big proponent of most of one's practice should be with one hand, each hand. Not very often in real life you have both hands free.
