Watched a few videos about Alien pistols and came away impressed. They clearly put some thought into it, and the gun is not just cosmetically different. The barrel is fixed and uses a gas pressure delay. The sights sit atop a removable rail that holds the slide on, also providing a zero-movement stable base. The hammer is located in the rail (no it's not striker fired) and swings downward, and the barrel is in-line with the web of the hand. The frame is aluminum, trigger release is crisp little movement, with a super-short reset. Showing it being shot alongside a conventional layout handgun, the difference in muzzle rise - or lack thereof is quite noticeable.
The gun's design would be perfectly suitable for personal carry for those who can afford one.
