The Beretta PX4 Storm is one of the many self defense pistols manufactured by one of the oldest names in firearms. The PX4 storm is available in several calibers, and can be easily converted from the traditional Double action/single action with a decocker lever that also acts as a manual safety. Beretta sells a low profile decocker lever along with low profile slide stop lever to replace the factory controls to offer shooters a more concealable package and less snag potential for their defensive carry gun. The only catch is that this low profile kit only works once you have done the Type G conversion which converts the PX4 to a decocker only and disables the safety.
