I have a quershion.
I have a friend on the Henry County PD. They are transitioning from the Glock .40 to the 9mm. Gonna use a hollow point plus p 124 grain round. Said they were shown a video with the two using the same grain bullet and the expansion was the same.
If you carry the .40, would you not use a bit heavier round, therefore creating more penetration by virtue of weight? this would make the comparison invalid, no?
The other reason was that .40 ammo was not as easily available.
What type service weapon do most of you carry? And if it was open selection, which would be your personal choice?
I'm a .45 ACP guy. But I don't carry for a living.
