SHOOTER
The 124 is longer than 115 usually, so the more bearing surface you have to the rifling will give you better stability on your bullets going thru the barrel, i prefer 124 gr as they do shoot better for me than 115 gr. i quit even using 115 gr bullets myself. Every little bit you do to stabilize improves your shooting period!
That's good reasoning.
Any given diameter (9mm), the ONLY way to make it heavier is to make it longer...
That gives more load bearing surface.
Pretty simple, but remarkably, overlooked.
I'm a CRAP pistol shot, but I do a little better with 124 grain bullets.
(I mean if I had to feed myself with a pistol, I'd have a crash diet coming)
My wife likes the 115s when she shoots pistols, her MP5 likes 124s better.
Says the 115s don't recoil as hard with her little handgun.
I don't have much of an opinion, doesn't matter that much to me since I don't do 9mm much.
Some firearms function better with one or the other, the few 9mm chambers we have don't seem to care much, but there isn't any plastic in the bunch.
We have a friend that EDC is a single stack Ruger LCP and it HATES 124.
Don't know if the plastic makes a difference or not.
