The Only 5 9mm PCCs With ZERO Feed Failures!

Most guys ranking home defense PCCs argue about which action type is smoothest. That is not the question that gets you killed. This video ranks the 5 most reliable compact 9mm PCCs for home defense: the CZ Scorpion 3+, CMMG Banshee MkGs, Springfield Armory Kuna, SIG MPX K, and the B&T APC9 Pro, the same platform the U.S. Army chose to replace its MP5 fleet. We break down direct blowback vs radial-delayed vs roller-delayed vs gas piston operating systems, where each one actually fails, and why feed geometry and magazine choice matter more than the internal action when you are running hollow points through a short barrel. If you own one of these guns or you are shopping for a home defense 9mm carbine in 2026, this ranking will change what you check before you trust it.
