In a 3.5" or 3" barrel 9mm like a GLOCK 26 and Kahr PM9 is a light fast bullet better like Corbon's 90 grain or 115 grani +P load or is a slower heavy load better like a Premium JHP 147 grain. Or the middle ground 124 grain JHP. I shoot 115 WWB exclusively for practice but find 124 Fed Hydras are dead on out of my GLOCK 26. But I will be getting a Kahr PM9 for ccw and am looking for the best load in terms of terminal ballistics and accuracy of of the little PM9. Is the accuracy based on a gun by gun basis or is it pretty general for barrel length?
