There's no searching. The problem is staring you right in the face, just open your eyes.

The problem is very very short barrels of tiny pocket pistols. When you get down under 3” of barrel length, this design will add to your barrel length an amount approximately equal to the cartridge length without adding anything to the overall length of the pistol.

So for a 9mm cartridge, that means you lengthen a three inch barrel to a 4 inch barrel AT LEAST.

If you think that is meaningless in terms of muzzle energy, you better consult some ballistics data.

For longer cartridges, like a 10mm, the effect will be even more impressive.

If you want a 'pocket pistol' with a short barrel, there are plenty of those on the market. The only people who are going to buy this thing, assuming they ever actually produce one of course, is suckers with more money than brains.
