how to make your pistol fire three rounds at a time?

Answer 1

Bound's hubby here:

You can not legally alter a pistol to fire a "3 round burst"! To do so would alter the firing mechanism, making the firearm unsafe. Such a modification would make your pistol a "machine gun" (fully automatic), making it illegal and you, as the possessor, illegal!

Answer 2

I'll go in another direction here. While the strict definition of a "round" is an entire cartridge, and firing three cartridges at a time would incur the wrath of the ATF, or be the result of having someone perform a trigger job without fully understanding what they were doing, it is possible to fire three projectiles from a handgun at a time.

First, and most obvious, are the various .410 shotgun "derringer" style handguns. A few manufacturers produce a .410 cartridge loaded with three 00 buckshot pellets. Those two, used together, would fire three projectiles with a single shot.

Another option is a cartridge which was manufactured for a while but I have not seen any in a long time. I believe there were called "Multi-Ball" or something like that. These were again basically shotgun pellets loaded into .38 Special, or .357 magnum cartridges, and perhaps a few others as well. I believe the .357 loading had three pellets which would of course all be launched with a single shot. This is not the snake-shot or survival loads that are still available, but a loading specifically manufactured to fire buckshot sized round balls. The fact that it isn't commercially viable any longer should tell you how effective it was.

Finally, depending upon how competent you are with your reloading, you could load your own multi-projectile cartridges. I have done exactly that using solid wadcutters (DEWC) in .38 Special cases. It's an effort to cut the bullets into segments, insure that all surfaces are flat, line them up properly while loading, and get a good crimp on that top segment holding everything in place, but it does work. With a typical light target load for the .38 Special, these gave me groups of about 4-6 inches at 15 yards, and yes, I did shoot them single loaded to be safe. This is not near worth the effort involved, but it can be done because I have done it.

Now if your intention is to have your pistol fire three rounds, as defined by three complete cartridges with a single pull of the trigger, then you will either have to move to a Class III type firearm, or risk injury and/or death by making those modifications yourself.

Answer 3

While it is illiegal, there's also no easy answer, even if you had all the paperwork in place. You need some form of indexing and resetting mechanism that will count off the three shots and then hang onto the hammer for the fourth round. In a pistol there's very little space to work, so it would be a very careful mechanical design. It's not something you can just do as a hack.

There are variations on the theme, other ways of doing things, but that's basically it.

The normal semi automatic trigger action has a sear and a disconnector, when you start to squeeze the trigger it moves the disconnector into place to catch the hammer, as you continue to squeeze the hammer drops off the sear and fires the gun, as the action cycles it pushes the hammer past the sear and it is caught by the disconnector. To allow the hammer to drop off the disconnector you need to release the trigger, so the hammer drops onto the sear.

In full auto weapons the disconnector is tripped off by the bolt closing. If you remove the disconnector, which is the same fault as having a mistimed sear/disconnector interraction, the hammer just follows the bolt home and the weapon doesn't fire.

Just so we are on the same page, possessing one part of a fully automatic weapon mechanism is illegal in the US. Even if you don't have the basic weapon to put it in.

Answer 4

A pistol that fits that discription does exist. It is called a Beretta 93R and it has a selector switch which enables 3 shot bursts. Im not sure if it is posible to modify "any ol pistol " to do this. And if you could it would be very illegal. You can own full auto weapons, but the government makes you jump through hoops and puts a hurtin' on your wallet.

Answer 5

That is seriously illegal. You can not manufacture a new full-auto since 1986. Three round burst is considered the same as full auto. You will need to buy a $200 tax stamp and procure a transferable full auto. It is not possible to do legally (convert a post '86) and you will be in a world of hurt if you try it.

Answer 6

you can not make a pistol fire 3 round if it is an auto you can hold the trigger down and go thou the chip . if it is not you will have to pull the trigger each time to fire .

Answer 7

Join the military, they'll make your rifle fire 3 rounds at a time.

Answer 8

3 barrels,3 firing pins, one trigger and one strong arm.

Answer 9

Stick 3 bullets in the barrel at once.


(Shh! Nobody say anything - let's see what he does ...)

Answer 10

You only have one firing pin so you can not do it DA.
