> You have NO IDEA how effective
That's a problem when your life, and the lives of your family and buddies depends on 100% reliability.
By far the most popular handgun ten years ago was the model 1911. So named because it was first made in that year, 1911. 20 years later, it had been proven extremely reliable so that's what professionals and careful civilians caried for almost a hundred years. Besides handguns, almost all trusted guns, from shotguns to ship cannons, were designs from John Browning or Samuel Colt. If you aren't Browning or Colt, we're not trusting our lives to your "clever", more complicated design.
After about 75 years of different people trying, Gaston Glock came up with a design which might rival the 1911, so after it was proven in military and police testing and proven in the field for 25 years, a lot of people switched from the 1911 to Glock. That's the switch, from a model that stood the test of time since 1911 to somethinf better only 90 years later.
Take your "you have no idea if it'll work" and do the USMC testing to it - bury it in wet sand, pull it out, and see if it fires reliably, every time. Keep that up for 25 years and maybe we'll trust our kids' lives to it. Until then, save your "maybe it'll work, maybe it won't" for video games.
