  1. Yeah. It seems an high quality firearm, with some very clever solution implemented.

  2. I approve of this gun. Give Mr. Obregon a medal and a piece of Texas!

  3. There are some rotating barrel delayed blowback (Savage 1907 and derivates and the French MAB PA-15)

  4. Patents on industrial designs last for 14 years, extendable to 21. So they expire pretty fast.

  5. It's a foolproof safety. For those that think to have unloaded the gun by removing the magazine, forgetting about the round in the chamber. It's the most common cause of unintentional discharges.

  6. Yeah. The magazine safety is a foolproof safety (for those that remove the magazine, but forget the round in the chamber) but, if you really need to fire the gun without a magazine...

  7. The locking lugs all around the barrel are kind of an overkill. They are not really needed. By simply interrupting the ridges on top of the barrel of a standard 1911 (so that they lock-unlock by rotating the barrel) you would have had the same number of locking surfaces (three) mantaining the slim profile of the 1911. The Beretta Cougar / PX4 only have one locking surface.

  8. The PA-15 uses the same system of the Savage 1907.

  9. Rotating barrel, tilting barrel and tilting locking block are different ways to obtain the same thing, a short-recoil breechlock handgun. Every system has its pros and cons.

  10. 11.43mm is the diameter of the projectile. 11.25mm is probably the diameter between the lands of the barrel.

  11. The three locking lugs all around the barrel are kind of an overkill actually. They are not really needed. The Beretta Cougar / PX4 only have one locking surface of this kind, and it's enough.

  13. Compared with the tilting barrel design, breechlock rotating barrel actions tend to reduce perceived recoil, but are more demanding in terms of precision machining and, since there are more sliding surfaces, in terms of lubrication needed. The gun can be more accurate, since the bushing of the slide can be tigher, but in a typical handgun fight scenario, that's hardly noticeable.

  14. I really like that design, but I heard that they kicked a lot. How was the perceived recoil?

Existing designs, even if more complex, can be cheaper to manufacture because of scale economies.
