I'm sorry, I don't understand. Hasn’t the bullet already left the barrel by the time your finger is past the break and is proceeding to press the trigger further toward the rear after the round is fired?

You may be surprised how much of a difference this kinda thing can make. I'll tell you my experience with trigger pull follow through:

Shooting with the M16 at Parris island in 2002, I started off pulling the trigger until the shot breaks during my "natural respiratory pause" then immediately letting go. A Drill Instructor smacked me on the side of the head several times while simultaneously screaming "FOLLOW THROUGH". I began squeezing until the shot breaks during a "natural respiratory pause", and then holding it until I began the next breath. I IMMEDIATELY cut my groups by over half.

There are several things that can be done after the bullet leaves the barrel that will unbelievably affect accuracy. These are things that generally affect shooting form, and not so much the actual trajectory of the bullet.

Lifting your head immediately after the shot breaks to try and see where you hit is one too. Once I broke that habit, I went from sharpshooter score to expert score.

Yeah, sure . . on a rifle, but even on a pistol that just has a few inches barrel?

YES! YES! YES! Even then, with a shorter barrel, these things than can affect form, will affect handgun accuracy just as much, IF NOT MORE, than a rifle. Handguns are normally inherently more challenging to shoot accurately, because of the shorter sight radius, and fewer/smaller points of contacts with the firearm (shoulder stock, fore end vs a single grip to hold onto).

Usually, inaccurate shooting is more pronounced with a handgun.

Again, I'll relate my own experiences. I'm pretty new to the 1911 platform, having bought my first and only on Valentines day last year.
I started out with the arched main spring housing, and with a grip that consisted of wrapping my hand around the grip, like I was trying to strangle it.

Now, I hold it by putting the Web between my forefinger and thumb high and centered under the hammer, and wrap my fingers forward from that point. Accuracy improved.

I changed to flat MSH to help facilitate that grip, and accuracy improved more.

The problem was, the gun was torqueing and twisting as the round fired. The bulk of the effect was happening after the bullet left the barrel, but it was enough of a problem that it was affecting my accuracy in a huge way. By changing my grip, and a part to help me along, I pretty much eliminated this problem. Again, it was an issue that affected my overall shooting form, and really had nothing to do with the accuracy of the gun itself.
