Rotary Action Autopistols—What Are They, and Why Do You Need One?

Rotary action pistols are somewhat rare when compared against more traditional tilting barrel designs. With a rotary-action pistol, the results are similar, but the method differs. The barrel and slide still remain locked together for a hot second until pressure drops. However, as the slide travels back, the barrel rotates, rather than tilts, to unlock from the slide.

With an assist by Italian design firm Giugiaro, the PX4 Storm looks pretty nifty.

Beretta .40 PX4 Storm Pistol – A Closer Look – Range Report

One of the standout features of the Beretta PX4 Storm is the rotary action short recoil system. Like most other 9mm and up centerfire pistols, it uses a short recoil system that temporarily locks the slide and barrel together for a hot second during recoil, allowing the pressure to drop to manageable levels. After a fraction of an inch of rearward travel together, the slide and barrel separate, allowing extraction of the cartridge, recocking, and chambering of a new one. The PX4 just goes about that locking and unlocking process in a very different way with the rotary system.

If you keep a DA/SA pistol at home for self-defense or range use it makes a lot of sense to get a DA/SA subcompact pistol for concealed-carry, too.

The Beretta Px4 Storm Type-C – Gunfight Safety at its Best?

Nobody wants to shoot someone by accident, not even if you already shot them once. But something that many people don’t understand is the criminal and civil liability that can arise from doing just that. It is hard to think about a concept such as “gunfight safety.” It is an oxymoron of sorts because a gunfight by nature is not safe. But when you choose a firearm, for concealed carry or as a duty gun, as a police officer or private security, you have to consider how likely is that gun to get you in trouble if you are in the heat of a potential or actual gunfight. Even if you are protected by statute from criminal liability as a police officer or if you live in a state with castle doctrine laws, lawyers can find a way to sue you regardless, and your ability to not fire the gun under stress could potentially effect your life as much as being able to fire the gun under stress.
