Fisheye, sounds like you were on a skeet pad and only shooting birds coming at you? If you shoot birds going away from you, from the house closest to you, those are very easy shots! Just swing your barrel up on to the bird and as soon as you "cover it" with your muzzle, pull the trigger. Your light weight fast moving barrel will smoke those shots. Just turn your brain off. ALWAYS assume you will hit the bird. Never even think about missing, just hitting. Personally I always think "kill it".
If you hit 50% of the birds coming at you first time, you should hit 80 to 90% of the going away shots.
Pistol grip will probably slow you down on swings to left or right or shooting doubles, but for shooting singles coming at you or going away, not as big a deal. Honestly, hold off on the pistol grip and get in a groove with your gun as is, unless you already have it on? Then in a few months put it on.
The most important thing is you just went out and shot at a fast moving target the size of your hand. Your 11 misses most likely would be solid hits on a human sized target moving much slower!
Find a five stand to shoot and get a few friends to go too.
