Pistols are a popular firearm for cops to carry, and they have been used in the United States since before there was such an idea of an “assault weapon.” Many police forces around America still use revolvers with either single or double-action triggers. However, some agencies overseas do not allow pistols without their magazines being full because it’s considered unsafe by them–though American law enforcement officers will always make sure you’re carrying one bullet chambered at all times when on duty!
