What Everyone Is Saying About Glock Accessories

By Kristen Baird


The Glock 9 mm semi-automatic pistol is regarded by many as America's favorite handgun. Using the right Glock accessories can make shooting easier. First, it is essential to understand the basic principles underlying all firearms. At its simplest, a gun is a closed metal tube with one end open and the other end, which is rounded, drilled with a tiny hole to accommodate a flammable length of fuse. Gunpowder, a mixture of potassium nitrate, charcoal, and sulfur, is placed into the closed end of the tube (the breech). The earliest functional model of this apparatus was the cannon.

When the fuse is lit, the gunpowder ignites, creating a large volume of very hot gas. The pressure on the cannon ball as a result of the gas is greater than the atmospheric pressure coming in through the open end, so it is propelled out of the tube at a high rate. Note that it is the momentum of the cannon ball (mass times acceleration) that causes the damage at the other end; the projectile itself does not ignite or explode.

The disadvantage of early handguns was that they could fire only one shot at a time, after which the shooter had to clean and reload before firing the next shot. Next, came the revolver, which only needed to be reloaded after five or six shots had been fired. The ammunition, called bullets, rested in a revolving chamber until needed, when they advanced into the firing chamber.

Revolvers were great, but they still weren't fast enough. Enter the semi-automatic pistol. The revolving cylinder was replaced by a bullet-carrier called a magazine, that fit nicely into the butt, or handle, of the weapon. Larger magazines are had a capacity for up to 15 bullets.

The trigger action in a pistol is also lighter than that of a revolver. The down side of the semi-auto pistol is that it has a capacity to jam, a feat that is nigh impossible for the revolver. Lastly, automatic pistols fire bullets automatically as soon as they load into the chamber.

The Glock is a semi-automatic pistol developed in the late 1970s by an Austrian engineer named Gaston Glock. The Austrian army found itself in need of a new sidearm and so invited manufacturers to submit designs in response to a 17-point request for proposals (RFP). Glock owned a manufacturing company and led a team of engineers and designers to put together a design incorporating a plastic frame as well as metallic components.

Satisfied with what the Glock team came up with, the Austrian Defense Ministry ordered 25,000. Widely considered America's favorite hand gun, the Glock is made in all major calibers, of which the 9 mm is the favorite. Among the accessories available for the sidearm is the magazine. The Glock magazine holds more ammo than magazines of other gun manufacturers.

What is intriguing about the Glock magazine is the difference between those made for use in European military and law enforcement agencies, and the one preferred by American users. The practice of allowing the magazine to drop onto the ground is frowned upon by shooters in Europe, while the Americans insist on it.
