Yesterday the dog wrote a revolver and automatic pistol combination of the Lanstad pistol, a small partner in the comment area said that there is a modern automatic / revolver combination using triangular bullets, so this article will talk about this goods - Dudick Dardick pistol.
Designer David Duddick himself was a Russian-born Jew who later immigrated to the United States. The man himself was not very angry, but he had a little friend named Melvin Johnson, the designer of the Johnson M1941 semi-automatic rifle (Shunshun one). Dudick worked with Johnson on the design of the Dror Light Machine Gun (Johnson Machine Gun Variant) and was involved in the development of the SPIW program. Therefore, this brother can be regarded as an unlucky child who has made achievements in the field of firearms, but has not achieved anything in his life.
In the late 1940s, Dudik began working on an open-ended bullet wheel feeding system. Because the revolver's bullet wheel is closed and can only be fed from the rear, this sand-carved structure, the Landstad 1900 pistol, which has been wrongly demonstrated, has been wrongly demonstrated, so the dudick's open bullet wheel is fed from the side and can be fed through the magazine.
By the 1950s, he began to think about the possibility of triangular ammunition, a demand that had been proposed by the U.S. military. Because they felt that if the shell was triangular, the same amount of charge would save 50% of the space when stacked, after all, the triangle and triangle were stacked with few gaps and high space utilization.
In any case, In the 50s, Dudik first designed this pistol according to its original open bullet wheel idea and the military's triangular ammunition needs, but this gun did not consider being promoted to the military, but first put it on the civilian market to explore the way, so its ammunition is only .22LR and .38SP caliber entertainment/self-defense bullets.
These two ugly things that look like chicken legs are divided into two, 1500 type and 1100 type, nothing more than the former has a maximum magazine capacity of 15 rounds, the latter 11 rounds, and the switch between the two calibers of .22LR and .38SP can be achieved by changing the barrel. That's right, unscrew the screw with a slotted screwdriver to remove the barrel, very grumpy.
In addition, because the .22LR and .38SP are one edge fire and the other is center fire, the firing pin is in different positions. Therefore, After Dudick changed the tube, he had to tighten the screw at the arrow to adjust the firing pin position.
The structure of the whole gun is similar to that of a revolver, without that set of recoil mechanisms, relying on trigger force to rotate the chamber. However, ammunition supply and shell throwing are relatively new.
The pistol is fed through the magazine in the grip and the open wheel (lower left corner) above the spring, and like a standard double-action revolver, the wheel is turned first each time the trigger is pulled, so that the next round of bullets is aimed at the chamber and fired. The empty shell will eject from the ejector in the upper right corner with the next turn. The above Dadik instruction manual says that there is a gas boost, but I really did not find out how it uses gas to help the double-action structure...
It is worth mentioning that this pistol is not a magazine for ammunition, but a fixed magazine. Its feed port is on the left side of the gun body, after opening the compartment cover, the LOGO position above the compartment cover is whether it has a bullet indicator in the chamber.
Seriously, The Method of Feeding the Chamber through the Magazine of The Dadik and the Ranstad pistol we talked about yesterday are similar to those of Da Vinci and The Handgun.
But... First of all, is this triangular bullet really space-saving??? In order to save manufacturing costs and weight loss, it even uses plastic shells, but compared with normal bullets, it is also a circle of fat.
And although the plastic shell has made the shape of the Lailo triangle to increase the reliability of the bomb supply, the dog watched several foreign test videos, and the shell of the bomb supply is still very serious... There are also these .38SP and .22LR can be mixed, in case the .22 barrel is loaded with the .38SP, the consequences are very interesting.
In addition, Dudick also designed a carbine replacement kit for the pistol, and when it was put on, The Dudick had a stock, a handguard, and a longer barrel.
In short, the gun sold very badly, from 1959 production to 1962 the company went bankrupt, he sold a total of 40 guns (also said to be 100), it is reasonable to say that this rare sand sculpture product should be very popular in the eyes of collectors, right? No, because its bullets were so rare, most of the bullets sold that year were difficult to fire, and now no manufacturer is willing to re-produce, plus the Dudick pistol itself has not experienced a special war, let alone from the master's hand, so it is more than a thousand dollars in the collectibles market.
Dudick himself was involved in the US military's SPIW program (a branch of the salvo) after the company's bankruptcy, and he was very open-minded about designing a tri-pack of triangular ammunition for the prototype rifle, but then we also knew that it was cold.
