From anyone with experience with "Stun Guns", how effective are they? I've heard (from this video http://www.youtube.com/watch?v=AcOMhnf38LE) that the actual TASERs - the ranged ones that launch electrodes into the target - are good at incapacitating by disrupting the nervous system, but that...

@Sam1911 The difference that this would make is most likely pretty minor, but I figured I'd say it since it does occur in open bolt guns, but not in closed bolts (at least not with the bolt anyway; maybe with other firing mechanisms) Whenever something is pushed, it doesn't behave like it...

Here's my thinking on open bolt, fixed firing pin API: It's not true API, but it produces effects similar to API. In "traditional" API, the cartridge is ignited by a mobile firing pin while the bolt is still moving forward. As Sam1911 makes clear, the cartridge could not fire while the bolt is...

My mistake. I was referring to short recoil mechanisms, not short action.

@ Jim K I think I recall hearing that while the blish lock did have an effect, it was overall insignificant. I say this because I also recall that one of the changes between the M1/M1A1 and the previous models was that the recoil springs were weakened to reduce rate of fire. Perhaps this is...

@Nom de Forum It's not really a specific person that determined this, it's common convention that handguns with rounds 9mm parabellum or larger are typically short action, or have some other means of delayed blowback. I mistakenly took this and applied this to sub-guns, with the "logic" that...

Is this found on all of your blowbacks, or only on ones that fire "larger" ammunition?

From what I hear the blish lock was ineffective in practice, due to the limited adhesion of the bolt to the bolt face. Brilliant concept though.

Thanks for the info. So I guess blowback delay systems like short action are a result steel being the "best" material to produce a firearm with at the time.

Huh. So basically the 9mm Mak is considered the general cap for direct blowback not because it becomes difficult to manually cycle with any larger round, but because it becomes uncomfortably and inconveniently heavy for a handgun with a larger round. Hence why direct blowback can be used on...

I suppose I misread the "round cap" for direct blowback. The way I understood it, if a round was larger than 9x18 Makarov, then the spring large enough to push an appropriately large slide or bolt would be so strong, that the device would be virtually un-cockable. Could it be that 9x18 Mak is...

I thought the MP44 was gas operated?

@rcmodel Even if the spring didn't help to keep the chamber sealed long enough, wouldn't it have to be stronger on a larger bolt in order to accelerate the bolt enough to load a cartridge into battery and (in the case of an open bolt) fire it? Although I suppose I hadn't considered that closed...

@Sam1911 I have heard of this, but I've never heard of it being used in submachine guns. Is the idea that it only happens as a coincidence of the design?

So I've been taking a look at some World War II era submachine guns (such as the M3, Thompson M1, MP-40, and Sten), and I noticed that unlike modern submachine guns (such as the H&K MP5), these have no delayed blowback method- they are simply direct blowback. I thought I might be missing...
