Certainly, no one would be surprised by the fact that the instrument applied purely on the land, and one that is used by the sea must be different. We are not talking about the options for pistols and submachine guns, able to fire in the aquatic environment, and conventional weapons, adapted to fire in the air, but for all that are in close contact with sea water, and hence it is not excluded ingress guns. Try to figure out what exactly is different from conventional instrument samples for example pistol Walter PPQ Navy, which appeared relatively recently, but has already established itself as an instrument of reliable, durable and efficient.
First, you must remember that sea water contains quite a huge amount of salts dissolved in it, which makes it particularly disastrous for parts guns. In fact, go into details here and do not need every car owner knows how salt can quickly ruin the car body, in the case of firearms situation is not better. Naturally, constant cleaning and lubrication almost completely offset the harmful effects to marine water cannon, but absolutely clean gun after each bathing its accidental fall off the hands, because the solution of this problem rests on the shoulders of the manufacturer, not the consumer. Unfortunately, the «classic» cover surfaces of the parts may not provide protection from exposure to salt water, because those methods that are suitable for coating parts in past generations P99 pistols in this case do not fit. Way out of this situation became teniferirovaniya process, which is one hundred percent Russian developments DA Prokoshkin dated 1972 year, but extensively used by various foreign firms, not only armories, and positioned as a unique and sobstvennootkryty. However, in the case of gun PPQ Navy, this development has really improved. The fact that the very essence teniferirovaniya procedure is that the item is immersed in the molten salt at the highest temperature, in this process appears on the workpiece surface film, abrasion-resistant and protects item absolutely brutal environment from the impact, such as seawater. But this process of machining there is a negative trait in the form that the part surface becomes rough, and if you put her back grinding, then the integrity of the protective coating can be broken. The solution to this was the following oxidation prepyadstviya parts, creating another layer of protection, then polishing took place on a brand new layer and part of the first, and after oxidation ago. This ensured full coverage details the protective layer that even fairly long operation protects the item.
But not only the salts dissolved in water, fatal to the guns, the very design of the gun is slightly different in detail from the gun for sushi, though again I remind you that the gun itself is not adapted for shooting underwater. More precisely, the gun to shoot something, maybe it will be able to, but that’s simple bullets, or rather their bullets are not adapted for the usual «flight» in the water — in a medium with a density exceeding the air repeatedly. Despite the simplicity of the device implements, and in it, almost always, is really very simple, individual nodes can not work normally after aqua procedures. For example, the gun PPQ Navy striker moves in the gate channel, in case when the channel is filled with water, the motion of the impactor is greatly hindered. To solve this dilemma, in the gate foreseen separate hole in which water will be displaced by the motion of the striker and as a consequence do not have a situation where power is not enough for the striker conventional pinned capsule. The very same mainspring has greater rigidity required to overcome the resistance of the water in the channel gate drummer. A similar decision prepyadstviya applied in such recognizable as Pistol Glock. So Makarov pistol, even lain for several days in the water can be recovered and used immediately, without waiting until the water runs out of the gun, and even more of its cleaning and drying. Maybe for someone stupidity seem that such an instrument exists at all, because I do not drench gun may seem completely tasks. But, even with all diligence on the part of a man with such a weapon, such a situation can not be excluded. All the same, people trust their lives to these weapons and let them have a gun just not right.
The appearance of the gun PPQ Navy remembers very last model guns. At least, silhouette pistol remained practically without changes, but some innovations there, so no description can not do. First, it should be noted surface handle guns, which almost completely eliminates the possibility of a gun in her hands sliding arrow arrow, regardless of that between the arm and hand, water or a layer of silt. With all of this handle has retained the ability to install the rear part of various sizes, allowing you to adjust the size of the palm cannon shooter. Of safety devices, there is only a double trigger, which is quite enough, provided that the instrument of Resettled trigger mechanism with dovzvodom drummer, although the switch is a circuit breaker would be very well looked on both sides of the gun. Pieces of gun control has only trigger very long lever slide stop, magazine release button, as there is a slider designed for disassembly tools. On the shell-gate there are ample and deepest notches which allow confident delay shutter even if he or arrow hands soiled anything slippery. Sights open and consist of the rear sight and front sight marked svetonakoplyayuschey paint. Fascinating aspect is that the instrument can be equipped with 2 variations trunks, one of which has a thread for a silencer device, in the case when it is removed, locked thread protective cap. Interestingly as well, and that the device itself is silent shooting another company — Brugger & Thomet AG, while all previously performed only by Walther. Under the gun barrel on the frame has a landing place for mounting compact flashlight or laser pointer, although many dispute the need for these devices in arms, citing the fact that with the same laser pointer shooter focuses only on the spot laser pointer, which can not be seen by the fact or other reasons that may cause a delay before firing.
Automatic pistol built on the mechanism of work with little recoil gun barrel with all this comes into engagement with the housing-bolt means projection above the chamber and the window to eject spent cartridges. The whole system works properly followed. When you press the trigger occurs dovzvod striker pistol, and after its collapse. After impact, the primer ignites the initiating composition, and after the powder, which leads to the formation of vast quantities of propellant gas which is pressurized to its increasing volume. Because the cartridge is in the barrel gun powder gases have nowhere to go, and they tend to increment the distance between the sleeve and the bullet to free himself greater volume. So Makar, powder gases with similar force pushing the bullet down the barrel and sleeve backwards towards the shooter. But Donets sleeve abuts the bolt pistol, which in turn is connected to the barrel through the window to eject spent cartridges and the projection over the chamber. Taking into account that the weight of the bullet is substantially less than the whole structure, it leaves the barrel earlier than automatic gun starts moving. The motion of moving parts in this case provides not that put pressure on the powder gases sleeve, causing it to push the bolt back, but that impulse is transmitted through the sleeve gate because no sleeve pushes the shutter and the shutter extracts from the chamber liner. So, after a shot barrel and slide start to move backwards, with all this under a projection chambered barrel with shaped neckline, which is threaded pin extending through the frame guns. This cutout is made so that when the trunk reverse it leads interaction with the pin and forces the breech down. This causes the protrusion of the cartridge chamber of the weapon out of adhesion to the casing, and the shutter closure is continued movement alone, without the stem. Extracting and ejecting the spent case her cover-gate comes to own the rearmost point and stopped for a split second. Under the influence of revertible spring he starts moving again, but in the reverse direction, removing the new cartridge from the magazine, he inserts it into the chamber and abuts the breech that forces the barrel to move forward. Ago, because of the effects of cutouts, and a pin passing through the frame of the gun breech is raised ledge above and chambered comes into engagement with the window to eject spent cartridges that locks bore pistol.
The combination of one of the most reliable schemes for automatic pistol, quality machining tools, reasonable implementation plastic guns and the ability to adjust to the peculiarities of palm hand made this gun really good prototype, which is already in its short existence of market instruments has spread not only in their homeland, and beyond. It is also important and that gun has a size and weight suitable for fully nestled wearing, including everyday. So the weight is only 695 guns without bullets c variant chambered in 9×19, in case if the instrument is designed for ammunition .40 S & W is the weight of the gun will increase by only 10 grams, making a lot of questions that have no answers — commercial Enigma. Length pistol chambered in 9×19 version is 180 millimeters, chambered .40 S & W is equal 184 mm, respectively, barrel length is 102 mm and 106 mm. Thickness of 34 mm guns, which is quite a lot, but on condition that the boundaries of the pro-gun parts not present in practice it does not make any inconvenience. Both versions of the gun its height is 135 mm. There’s also a rumor that the instrument will be valid for ammunition 9×21 IMI but for now it’s just a rumor. Magazine capacity cartridges using 9×19 is 10 rounds (for the civilian market) 15 or 17 rounds. In the case of cartridges .40 S & W magazine capacity can be 10 rounds (the same back to the civilian market) 12 or 14 rounds.
Summarizing all the above, it should be noted that such an instrument, as Walther PPQ Navy, if not unique in its own way, it is quite rare, because only relatively recently manufacturers of firearms back to the realization that the standards used on land and near Water must be different from each other, to ensure their operation and even neotkaznoy to save. However, here there is another world — though what instrument should be reliable and durable in a variety of operating criteria, but, unfortunately, achieving this will cost very expensive. It would be interesting to draw a parallel with the Russian standards snub guns adapted for use near the sea water, but these, unfortunately, until the present. In general a similar instrument can be attributed to faster special, but because at the moment all the forces are focused on providing the army and police standards, which are necessary at first, then blame someone that «we have no such» not quite right, though let have recently emerged what is promised, and only later will be thinking about other swatches.
