Which GLOCK parts are the best?

Best in Bunch likes the Sightmark Mini Shot, Streamlight TLR-4 pistol light and laser combo, Pearce grip extensions, Zev Technologies and an upgraded take-down lever for easier disassembly.

Not too long ago, the world’s most popular handgun was just as demonized in the media as the AR-15 is today. Not because it was used in a mass shooting but because its innovative use of advanced polymers scared the anti-gun politicians and media into falsely believing it was a firearm made for terrorists. They spread the lie that this new “plastic” gun remained invisible when passed through metal detectors.

That pistol is the GLOCK.

Crime and Guns in the U.S. in the 1980s

In 1986, the year this “plastic” gun was first sold in the United States, acts of terrorism against the U.S.A. had been increasing, as well as the rate of murders committed with a handgun were on their way to doubling due to an increasing crack-cocaine epidemic. However, anti-gun activism started before the increasing drug-related crime in the U.S.A. An assassination attempt on President Ronald Reagan in 1981 led to the passing of the Brady Bill (Brady Handgun Violence Prevention Act) in 1993 requiring people to pass a federal FBI background check before purchasing a handgun. According to, “…the gun culture changed again in 1981 when John Hinckley, Jr. tried to assassinate President Reagan and nearly killed his press secretary James Brady instead. He and his wife Sarah became activists. ‘You can begin to see a sea change of attitudes during this time,’ said Sarah Brady. ‘The NRA was fighting against the cop-killing bullets and plastic guns, and we got into an alliance with law enforcement and we just got together and said, ‘What’s the first thing we should do?’ And we all said, ‘Background checks.’”

The revolutionary design and use of advanced polymers in the invention of the GLOCK changed the landscape of the firearms industry forever. According to GLOCK’s history, “In 1963, just outside Vienna, Mr. Gaston Glock began his professional journey with plastics and metals. In 1981, GLOCK Ges.M.B.H. was founded, and a profound series of engineering feats were on their way to being realized—accomplishments that would ultimately redefine the modern pistol.”

Gaston’s company made injection-molded parts and components using advanced polymers and began producing knives, grenade casings and machine gun belt links for the Austrian military. In the early 1980s, Glock, along with a group of firearm designers, developed the classic GLOCK 17 pistol to meet the requirement needs of the Austrian military—including a magazine that holds more rounds, a consistent trigger pull, quick yet safe to deploy, plus be lightweight. Gaston wanted it to be simple, thus incorporating as few parts as possible. Today, the Glock is comprised of only 34 parts. The SAFE ACTION safety system was developed and the rest….is history.

If you’re a GLOCK owner, you already know how reliable and durable the gun is from the factory. But no matter how GLOCK Perfect the gun is, it can’t make you a sharpshooter. Being a good shooter takes practice and training. However, there are accessories that will help greatly improve your accuracy. Better triggers, sights, optics, grips—these all contribute to the overall shootability and fit of the gun. These aftermarket enhancements will make aiming quicker, help mitigate recoil and aid in smoother operation. By adding GLOCK accessories to your pistol, you will become a better shooter. Here are some of our favorites.

Zev Technologies Extended Magazine Release Lever

If you are familiar with customization, then surely you are familiar with Zev Technologies—one of the top, if not the most popular aftermarket companies for GLOCK parts and modifications. Zev barrels and slides are some of the most precise on the market and are great if you are building a competition gun. The price is steep; however, if you want the same detail-to-attention that Zev Tech pays to their high-quality products, but don’t necessarily feel the need to completely pimp out your GLOCK, the extended magazine release lever will increase your speed when reloading. Featuring an over-sized head, the extended mag release allows you to perform tactical reloads

Pearce Grip Extension

Compact and sub-compact GLOCKs do not offer a full grip. Without altering your magazine, the Pearce grip extensions with finger rest design give you better control over your firearm by offering a fuller grip. These are easy to install and replace your magazine floor plate. The Pearce grip extensions have a fluid design and appear to come from the factory while adding ½-inch of more grip space. As a bonus, they help with faster mag changes.

GLOCK dominates 65% of the Law Enforcement market and is issued to many militaries around the world. Paul Barrett, the author of GLOCK: The Rise of America’s Gun, says, “No handgun manufacturer has a bigger presence. And in the law enforcement area, GLOCK is the biggest and most influential.” According to the Shooter’s Log, more than 12 militaries around the world have issued a GLOCK 17, while many more carry the GLOCK 19, including U.S. Special Forces. At last official count from GLOCK in 2007, 5 million pistols had been sold worldwide. This number has obviously significantly increased since, especially since GLOCK celebrated its one-millionth GLOCK 43 produced in only three years of the pistol’s life. With the 2018 release of the new GLOCK 19X and the upcoming G45, we won’t be seeing GLOCK’s popularity waning any time soon.
