  Video left me with more questions than answers. Like Knitepoet said, .45 ACP fmj ball ammo has much less spectacular effect on a water filled milk jug than a .45 ACP loaded with hollow points. He is also quite enamored with the FPE thing. I'm WAY more interested in the total energy dump into the target than the wasted energy from over penetration. But he's trying to sell a product, so a little bit of hype is expected.

  A Mac-10 in any caliber interests me as much as a 3rd term for Obama, but if it tickles your pickle. Run with it.

  44 mag energy from a 30rnd mag!!! Come on. I would probably slip a 1 1/2" section of spring over the standard recoil spring to suck up any extra energy but still wow. A scoped takedown sidecocker in this would be perfect for almost anything. Deer, bear, pigs, walls, cars just about anything you could want to drop!!! The great thing about overwhelming firepower is you might not always need it. Make it accurate out to 150-200yds it will do most anything you could need.

  And I, in contrast, barely give a fig about energy so long as I get fair tissue tearing and a hole completely through the animal - which I can do just fine with flat noses at standard .45 ACP pressures and velocities. As for the "revolutionary concept" of .44 Magnum energy from a 1911 style platform, that combination is called a .45 Winchester Magnum from an LAR Grizzly, circa 1980's.
  
  MAC 10 handgun -about as comfortably portable and ergonomically friendly as the cinder blocks he was busting up.
  
  MAC 10 carbine - why not an AR-based platform in one of the large bore rounds?

  Why would anyone want a self soiling AR. The masterpiece Carbines have an AR stock adapter and quadrail forend. The sidecocker allows a scope in the normal location on top in a package you would need a SBR AR to approach. The only sad thing is Masterpiece doesn't sell them as 460's anymore but the rep said everything was the same just the chamber was 1/16" deeper. So a few seconds with a chamber reamer and you have a badass multicaliber piece. Also the carbine sells for about $800 which is far less than any thumper AR. I will probably have about $400 into mine when done.

  Along with the .45 Winchester Magnum, there's also the .475 Wildey Magnum introduced in 1979. Both are pretty efficient large bore thumpers offered in semiauto pistols.

  Who cares about a squat to pee round like .45 ACP when there are still .45 Colt guns?

  But the Roland can be adapted to standard ACP handguns for a fraction of the cost. All of those are hard to find and expensive. it seems the Mac can shoot the ACP and Rowland interchangably.

  Actually, I'd RATHER have a five-shot, bolt action, RIFLE CALIBER carbine and rely on skill rather than the law of averages to hit anything. . .I mainly suggested the heavy AR because my preference just isn't what the cool kids are shooting this week.

  O.K. Here's the thing about all the MAC family of handguns. They're blowback action, and since they went with light bolts on them they have very heavy recoil springs by necessity. The MAC family were also originally envisioned and built as full auto machine pistols. As a semiauto, they are like a Shelby Mustang with the engine replaced with a Pinto 4-banger. Kind of blase.
  
  Then STEN and Sterling SMGs used a very heavy bolt which a. made for a less robust recoil spring, and b. made the cyclic rate more sane. The cyclic rate on the MAC-10 and MAC-11 machine pistols was insanely high by design. The MACs, having the light bolt and heavy recoil spring setup make it a sunny beach to cock compared to the STEN or Sterling, also. The recoil springs on a MAC-10 semiauto chambered for the .460 Rowland would be a good bit heavier than the .45 ACP version due to the more 'energetic' recoil and cycling impulse.
  
  FWIW, I've shot the semiauto MAC-10, and when cocking it, invoked the proper magic words and phrases from the Sailors Handbook. And also called it the proper names from the book. I have two M-11 9mm and hate both of them due to the cocking force required.

  Convert it to fire from an open bolt at full auto and see if Arnold can hold it. He'll be back! :nono: Later,

  Mac carbines are plenty capable of good accuracy as I proved with my Mac11 build. My favorite part is that it is an easy platform to work with. Just like any other gun a little attention to the trigger etc improves things exponentially. With a free floated tensioned barrel I would put it up against any similar carbine. Once I get my mill set up I could even make my own bolts and every other part but the barrel. Once I get a lathe that won't be a problem either. I guess I never really noticed the cocking effort but I'm pretty big. Now I am laying out a Mini9 receiver for my next IPSC/IDPA toy. I will probably make a 40S&W barrel for it so it can do major or minor. Stock with no optic or comp and a threaded barrel and rail to do modified and unlimited. Like I said a very versatile platform.
