Low bore axis measurement

I keep reading that pistols with a low bore axis will have less flip, easier follow-up, and see some pistols recommended over others.

Is there a measurement for this to compare one pistol from another?

I have a Beretta 92, and wonder how it compares to others, and maybe which pistols would be good candidates since I'm looking at possibly getting a .40 which from my understanding has more flip.

That's a very good question. I don't think the measurement is codified anywhere. Personally, I think of it as the distance between the center of the bore and the center of the trigger.

usp9's method would probably be easier to measure but I tend to think of it as the distance from the center of the bore to the highest point you can grip on the backstrap.

I really doubt you will find a measurement listed anywhere so you will need to get your hands on them and do it yourself, or you could just eyeball it.

Train enough with a particular pistol and the whole low bore axis thing won't mean much at all.

that is how i define it too. it's harder to measure, but it makes more sense, as it is the increase in leverage of the momentum of the bullet over the pivot point (where you are gripping the gun)

it's isn't to sole factor in determining muzzle flip.

in .40, i've used the Sig 229 and 226 (high bore axis), the Glock 22 and 23 (low bore axis) and the Beretta 96 (somewhere in between, but closer to the Sig). my Beretta 06 has the least muzzle flip and allows faster followup shots.

i think it has more to do with the Beretta action's non-tilting barrel

I wouldn't get too wrapped up in fractions of an inch, personally. :)
