Depending on the pistol (excluding .22) I can shoot about a 2" to 3" group at 10 yards, 10 shots, taking my time. I've been shooting pistol consistantly for about three years now including IPSC. The shooters on some of these shows have been shooting pistol for years and probably have better eyes than mine. Don't believe some of the forum posts saying they can shoot a 1" to 2" group off hand at 25 yards. I've yet to see it in person.

It takes a year of consistant practice before you will see improvements. Holding a gun (or any other tool) and becoming proficient with it takes time.
After a while, things will get better

Try chumming with some decent IPSC/IDPA shooters. Make it known that you ARE a new shooter ans you want to learn to be more proficient with a handgun.
Here's the hard part:forgetting the COD/TV/Hollywoodshyte you see. 99.9% of that gunplay is faked,staged,choreographed or all three.
Ears and Eyes open (and protected) mouth closed, and pay attention, and shooters will Be very inclined to help. It is in everyone's interest to see our sports grow. And there are very good shooters here, not just south of the border
Pistol is the most demanding firearm to learn. Short barrels and short sight radii compared to a long gun. Grip pressure in pistol is critical, as is trigger pressure. Plus the recoil is a bit of a handful.
Pistol is more about balance than brute force.
Best of luck

Year 1 for me was unlearning hollywood etc. as soon as I 'forgot' what I "knew" I started improving.
Year 2 for me was hanging around IPSC/IDPA matches. Asking questions, expressing interest in the sport
Until a shooter said, talk to that guy. He is a decent shooter and loves getting folks hooked on shooting.
Year 3 for me. Ok, we have accuracy and speed, and some experience with safe handling, now I'll spend the entire yeartrying to male all 3 work together in harmony.
Year 4
Year 5
