Wheel lock

Wheel lock:

The next generation of the match guns are the wheel lock guns.
May be the concept of the wheel lock is very simple , but the thought that  it would replace the match lock guns is revolutionizing.

Working:


The working of the wheel lock fire arms can be compared to the butane lighters.
In the butane lighters we compress the butane into the liquid form and it is covered by the steel wheel, so that when the wheel rotates against a metal, it ignites a small spark and the butane which can easily evaporate catches fire from the spark. So as long as the butane evaporates, fire goes on.......

So similarly wheel lock has a flint placed on the top of the wheel , and when the fire arm is triggered the wheel strikes the flint and produces a spark which ignites the gun powder and blows the projectile.




The above picture shows the mechanism of the wheel lock.


The mechanism in detail:




The wheel energy is stored in a spring which is loaded before triggering. The dog with an iron piece is placed on the wheel directly/ manually. The cap over the flash pan would pave a way for the sparks when they are produced due to the wheel lock mechanism and eventually the the gun powder in the flash pan ignites and the regular projectile work is done.
This mechanism has a great disadvantage when it comes to the durability of the springs.
These were used until 17th century and are replaced by flintlock guns.

Snap-lock , Snaphance and flintlock

Snap-lock, Snaphance and Flintlock These three fire arms work under same mechanism. The difference is the protective measures development  in each of the fire arms. The order of the fire arms is snaplock snaphance flintlock percussion cap Mechanism: The operation works on the old concept of fire sparks ( when two rocks are rubbed against each other the friction between them causes a spark and eventually fire when the sparks are in contact with a dry grass or to be more precise, a conductor which ignites under a slight high temperature). The firearm consists of a flint material and a steel plate placed against each other. When the flint is held with a spring, potential energy is stored in the spring. When the trigger is released the potential energy is transferred to the clamped flint and the clamp moves forward and strikes the hardened steel producing sparks. These sparks flash pan travels through the touch hole and ignites the gun powder and boom. ...

GLOCK 43 - the effective concealment

GLOCK has launched new GLOCK-43 9mm pistol few months back  #thebackupgun #pocketgun   This Glock pistol is similar to the GLOCK 42 but is slightly larger in its length. Even it can be operated with 100 grain rounds which makes its recoil less. We can obviously use 230 grain standard rounds. When it comes to the design its slim and compact. And the distance from the grip and the trigger is same as the larger GLOCK pistols, which makes it fit for all kind of users. Its grip is different from that of GLOCK 42 and it is recommendable for tight grips while targeting. Dimensions: overall length: 159 mm Slide length: 154 mm  Length between sights: 132 mm weight: 509 g width: 26 mm Slide width: 22 mm Height: 108mm For further reviews you can visit the following links: thetruthaboutguns policone.com americas1stfreedom.org singlestack9.com
