FWIW, I chronographed the Speer 124gr +P Gold Dots out of my Glock 26 and my Kahr MK9 and the 5 shot avg velocity was 1,232fps from the Glock and 1,200fps from the Kahr. That's a lot of energy from such tiny guns. Accuracy? No problem.
I am not a bit concerned about the 11 9mm 124gr +P Gold Dots that are riding on my hip right now. I am confident they will be effective if I do my part.
