i don't know if the new barrel is done the way it is for accuracy or cost... I don't like that it can't be swapped with other glocks. I think police departments will find that it's going to be far easier to match bullet and gun for evidence after a shooting... so your gen 5 will be far more easy to trace projectiles... back to your gun. I don't know if most people care... I guess I will care if it's harder to clean well.. I always thought the glock barrel was pretty easy to clean well. I never felt glocks were very accurate guns.. maybe that image will change ??
