Grip pressure and POI Shift

[Clusterfrack]

Free recoil affects POI in rifles and pistols, and will typically send the bullet high. In rifles, a heavier gun or a suppressor tends to reduce this. In pistols, a heavier gun reduces this a lot. Typically this is only a couple inches at 25 yds. But some guns seem more prone to stringing as a function of grip and stance. Gen 1 M&Ps are the best example of this. The barrel lockup was apparently not well designed.

I can hit 6” steel at 50 yds with a Shadow 2 gripped loosely. A G34 will send it over the top.

Grip pressure is irrelevant to accuracy to a single round fired.
Grip pressure is relevant to holding the gun still.

Two things matter:
1) The sights are aligned on target.
2) The sights do not move when the trigger is being pressed.

Once the trigger is pressed, you do not physically have enough time to alter the direction of the firearm before the bullet exits the barrel. If your round did not go where it was intended to go, then it was moved prior to the primer being struck.

Grip pressure is entirely relevant to follow up shots.

For those that rely on a strong support hand grip to shoot the Glock, what happens when you shoot with just one hand?

POI will be slightly high and shifted toward the side you are holding (sights do not lift vertically). Tucking the elbow and blading a bit helps with the windage shift.

I’d say that stronger grip pressure on a Glock helps ME manipulate the trigger with less chance of disturbing the sights.

I am out on the range now, and just shot a 25 yard Glock group, holding the pistol as lightly as I couldn’t and not have it fall out of my hands.

Wow, good shooting dude! Maybe 2” high?

It can, and does for me also, but it's not a universal requirement.

With a 25 yard zero, I expect my 9mm pistols and slug guns to be several inches high at 50, back on at 75 yards and then dropping. Assuming a center hold on a six inch steel at 50, wouldn’t take much to go high?
