My agency is in the process of moving from .45acp to 9mm. The powers that be are leaning toward choosing the Glock 19 as a service pistol over the Glock 17 in hopes that more officers will carry off duty. The word is that they are planning on going with the 147gr Gold Dot. I know that 147gr Gold Dot is on the list of approved ammunition for duty and self defense but I am under the impression that FBI test are conducted using full size handguns. I am a little concerned how the 147gr Gold Dot will preform from the Glock 19. Will the Gold Dot still perform well with the smaller hand gun or should we go with the 124gr +p Gold Dot instead. Thanks for any help you can give.
