I hope folks read more than just the title. So im watching a show with a gun exchange and the person has to reload and you can see they are nervous to get the new magazine in so they can fire again and it made me think. Do any guns have two magazine where you can either manually switch to the other magazine or maybe automatically do it when the first one is empty. With the idea that if you need to fire while in the middle of changing out the empty magazine you could. I feel like this seem obvious enough that someone must have tried it. I mean considering the crazy gun things I have seen. Since im not aware of anything I figure if it has been done it had an issue or was just not useful enough to make worth it. So for the folks that are really into guns, especially wierd protoype ones. Has there every been anything like this?

It's not really worth it. A lot more complexity for the trigger and firing mechanisms, barrel alignment; etc. Weight is also a concern with any carry weapon. There were a couple of weapons in history that tried a dual mag setup

MP40I
The Burton
AF2011 (More double barrel but does fire simultaneously)

There's also the DIY jungle style

coupled magazines, refers to detachable box magazines, and thereof, that are fixed together side by side, for example, with tape, or purpose made magazine clamps, also called magazine couplers. The spare magazine may be pointing downwards in relation to the one fitted to the weapon, as to keep the feeding lips clear for insertion into the weapon.

In general these days, belt fed weapons are used for more capacity where needed.

And extra large magazines. You can find glock magazines with 50 or 100 bullets.

I got turned on the mp401 which was what I was thinking. The whole point to me is to people to fire while reloading if you need to whereas the tape two together is just about faster reloading which allows it faster every other magazine swap. Im going to check out the burton so thanks for another thing.

Note, the designation is MP40/I not 1 :P May help your research.

luckily the search still found it. Its actually pretty much exactly what I was thinking but with a pistol.

If you're going to be firing while reloading, you aren't going to hit much. Practicing your reload can get it to a speed where the time of the loss of your ability to fire is almost indistinguishable from the time it takes you to get your gun accurately back on target after a shot.

yeah im not looking to use practical things myself it was more an idle thought while watching a show. Curious though. Would you never fire a shot unless you where accurately back on traget. Like to dissuade someone from motion who was armed?

Depends, if we're in the jungles of vietnam? Sure, suppressive fire, still need to retain ammo yourself though.

In a self defense situation in an American city? Bad idea, you're responsible for every round that leaves your barrel, if you hit a bystander while wildly winging shots at an attacker you're fucked and will be going to prison. Unless you're a cop, it would seem.

Well in most of the movie situations its an area where people are far enough away that the gunshots don't bring police and usually there are some family or such that is in a known direction usually behind them a ways that they are out of the fray. So its an idealized situation. I actually thought more pistol as soldiers will mostly be in a team where hopefully only one person is reloading at a time. I assumed that is why you would hear individual ones shouting reloading sometimes (again in movies). granted if separated and down to one I could see it being useful again. I mean im guessing given the 40i never took off so the idea is out there that it must not be all that useful.
