The real question is what platforms they are launching from? There are a number of .45acp platforms I just do not like, and am forced to run them slow and concentrate hard to maintain decent accuracy. There are only a select few .45acps out there that I can shoot as well as a 9mm........usually they are single stacked steel frame models.
Yeah .45acp makes bigger holes, but for department general issue I think it is a bad choice when you have to equip a wide variety of hand sizes, body sizes/weights, physical strength, and natural skill levels.
