glock 20 gen 4 upgrades

Glock 20 Gen 4 Upgrades - Glock is the most popular handgun brand in the United States. Glock pistols regularly appear on best-seller lists, equip more than 60% of American law enforcement agencies, and are recommended by many industry professionals. When a first-time gun buyer asks for a gun recommendation, the typical response is "get a Glock." When a firearm platform becomes very popular, like the Glock, manufacturers scramble to make third-party parts and accessories for the platform. Not surprisingly, the Glock's aftermarket size rivals that of a 1911 or AR-15 pistol.

The original Glock pistol, the first generation Glock 17, was designed in the early 1980s to compete in the Austrian Military Pistol Trials.

The Glock 17 reached the military pistol test as a high-capacity firearm that allowed 17 rounds in the magazine. It has a light, mostly polymer frame, a polygonal rifling barrel (more accurate and easier to maintain), and very few controls without a manual safety and no decocking mechanism. It features three internal safeties, including a drop safety and a trigger-mounted safety. It can be disassembled and reassembled quickly and without tools, using only 34 parts.

Glock's durable and reliable design emerged as the winner of the Austrian military pistol test. This led to its adoption as the P80. Joint testing by Norway and Sweden revealed that the Glock pistol passed every NATO durability standard, prompting both countries to use it.

In 1986, Glock opened an office in Smyrna, GA. Glock pistols began to be imported the same year and officially hit the market in 1988, attracting the attention of civilian shooters and law enforcement agencies.

In the 1990s, law enforcement agencies in the United States had to replace their aging .38 specialty revolvers with new, high-capacity semi-automatic pistols. Glock has launched an extensive marketing campaign, offering deep discounts and lucrative trade-in programs to entice law enforcement agencies to switch to Glock. The plan was a huge success; to this day, Glock pistols still equip 60% to 65% of all law enforcement agencies in the United States.

In the civilian world, the Glock has taken nearly every relevant shooting activity by storm. They dethroned the 1911 as the most popular competition platform. Experts often recommend the Glock as ideal for concealment and self-defense. Glock has even made a pistol model that is perfect for hunting.

Every part of a Glock pistol has at least one aftermarket equivalent. The Glock-compatible product line can be difficult to navigate, especially for newcomers.

The two most common complaints about Glock pistols have to do with the sights and the trigger. The front sight and trigger are critical elements for comfort and accuracy when shooting.

Other standard Glock upgrades include grip modifications, replacement barrels, magazine extensions, full magazine wells, full control sets, replacement slides, and accessories such as lights, lasers, and red dot sights.

Glock stock polymer sights. The sighting system consists of a square U-notch rear sight and a single dot front sight. While these sights are functional, most shooters don't like plastic sights.

Stock Glock sights are not illuminated. If you intend to use your pistol for home defense, you may want to choose night sights. Night sights do not require batteries and are available in two forms: tritium and fiber optic illumination.

If you want to install a red dot sight (RDS) on your Glock pistol, you will need to modify your existing slide or purchase a pre-cut slide. RDS compatible slides feature cuts and threads to install mounts and RDS.

Glock hit the civilian market with the MOS Gen 5 model. However, third-party manufacturers have been making RDS slides for decades. The RDS rail is compatible with popular pistols and micro red dot sights, such as Trijicon RMR or Leupold DeltaPoint.

Many slides include cutouts for a net rod or port, a front slide serration, and a flash cutout. Some models have a very nice design, literally changing the look of your weapon.

Comp Weight™ Compensator

Even the Glock trigger is best described as functional, providing sufficient pull weight for the pistol. It's not too heavy, but it has a decent amount of absorption and has a significant amount of very large travel after the break.

A common complaint is the shape of the Glock trigger shoe. Glock triggers are notorious for their trigger-mounted safety lever (dubbed the "dingus"), which some shooters find annoying or clumsy. Many aftermarket trigger shoes for Glocks come in many different shapes, some with lighter or different trigger safety levers.

Another type of trigger upgrade for Glocks is one that modifies the trigger weight. The stock trigger uses a 5.5lb connector, which takes between 6 and 7lbs. strength to pull fully. The exact amount varies depending on the model and age of the gun. Replacing the connector with a lighter model can reduce the towing weight. Many trigger kits also come with their own connectors.

Glock barrel stocks vary by generation. Generation 1-4 barrels use polygonal rifling; instead of land and ruts, this barrel uses less pronounced "hills and valleys", imparting spin to the projectile while traveling.

The 5th generation of barrels, known as Glock Marksman Barrels, uses a hybrid of polygonal and traditional lands-and-grooves rifling with a matching class crown, slightly increasing the accuracy in the range again. Gen 5 barrels are not interchangeable with Gen 1-4 barrels due to differences in external dimensions.

If you want to install Glock muzzle accessories like suppressors, muzzle brakes, or compensators, you'll need a barrel. The Glock Threaded Barrel is a slightly elongated barrel with a length of screw thread on the corporate end, which allows the user to screw in the accessories of their choice.

The special barrel of the pistol has a hole drilled precisely, which releases part of the gas expelled from the fired cartridge upwards. The force generated by these escaping gases pushes the barrel down, counteracting muzzle flip and helping the shooter stay on target.

Firing blank lead bullets through Glock barrels of any generation is not recommended. According to Glock, this can cause significant fouling, which can lead to dead batteries and, possibly, catastrophic failure. Individual aftermarket manufacturers offer barrels with traditional rifling grooves to solve this problem.

Glock 20 Gen4

If you have a Gen 3 or Gen 4 Glock, your pistol frame has a finger groove. Shooters who do not have large hands find the grooves inappropriate and uncomfortable, preventing people from getting a secure grip on the gun. Unfortunately, this often results in lower accuracy.

An inexpensive grip modification is grip tape: an ergonomically textured adhesive material designed to wrap around the frame of your pistol, partially filling the grooves and providing a gripping surface.

More expensive modifications include services that directly modify the frame of the gun. Stippling is a grippier etching process that adds a more aggressive texture to the frame, eliminating the need for tape. Some gunsmiths offer finger groove elimination services, smoothing and retexturing the entire grip in the process.

Upgrading your Glock magazine with a full baseplate allows you to increase the capacity of your existing magazine. Magazine extensions have plus ratings (+1, +2, +3, etc.), indicating the number of extra rounds available. Some baseplates are equipped with an updated magazine spring feature, increasing reliability.

The stock frame and magazine do not provide enough room for all fingers to grip the firearm on specific models of compact and subcompact Glock pistols. The baseplate upgrade is sometimes known as "pinky finger extension" because it provides enough extra material for the finger, which results in a better grip and, in turn, better accuracy.

A magazine well extension is a piece of polymer or aluminum that is attached to the bottom of the pistol frame. The purpose is to extend the magazine well to provide a larger opening for inserting the magazine, reducing the chance of "banging" the magazine into the frame, thereby increasing reload speed.

The term "control" refers to the Glock's magazine release button and slide release lever. There are two main types of upgrade controls for Glocks: ambidextrous upgrades and expansion controls.

The enlarged controls are a magazine release button and slide release lever that is larger than the standard option. If you have difficulty reaching buttons or levers with your dominant hand, you may want to purchase a larger control kit for your Glock.

If you are a left-handed shooter or frequently use the pistol in your non-dominant hand, you may want to install a magazine. ambidextrous release button. If you have a Gen 1-4 pistol, aftermarket parts are the only way to get an ambidextrous slide release.
