Last year when I watched a video from Forgotten Weapons on the Vz 61 I was really amazed by its small size, low recoil, and ease of control during full auto fire. Now, we can't get full auto here, maybe binary triggers will come in time for more guns outside the AR platform, but I started thinking about true machine pistols and if they had any value over a standard pistol. The H&K MP5k is pretty much a machine pistol due to its size and with the action it has that reduces recoil it has merit, but not for 3 grand. The Micro Uzi and MAC 11 are cheaper, but are regularly around $1000. They are blowback guns, the recoil will be more with them in 9mm and .380. At the next lowest price is the Vz 61 for $700 to $800 in the .32 ACP. Also straight blowback, but in the smaller caliber and at the same weight as the Uzi and MAC means the recoil is lighter than the 9mm and .380. So, what do you gentleman think about a semi auto variant of a machine pistol? Is there any practical use for them outside of collecting or range fun? Could they make good competition guns? Maybe even home defense firearms if fitted with a brace?
