If you’ve carried a duty pistol or bought your first 9mm in the last forty years, the odds are good it was a Glock. The Austrian polymer pistol that people once dismissed as a “plastic gun” is now used by the FBI and most US police agencies. But the lineup has changed fast: the Gen 6 and V series are now what Glock sells commercially, and parts that fit your old Gen 5 may not fit a new gun. Here is who they are, what they make, and what is worth buying.

Who Glock is

Glock is the Austrian maker of the polymer Safe Action pistol, founded by Gaston Glock in 1963 and based in Deutsch-Wagram, with US operations in Smyrna, Georgia. Its current commercial line centers on the Gen 6 and V series.

For its first two decades, the company made no guns. Gaston Glock made curtain rods, and in the 1970s he made knives for the Austrian military. He had no background in firearms when the Austrian Army went looking for a new service pistol in 1980, and he entered anyway. The result entered Austrian military and police service in 1982 as the P80. The name Glock 17 gets two explanations, the gun’s 17-round magazine or the company’s 17th patent, and you’ll hear both.

Gaston Glock himself proved hard to kill. In July 1999, suspecting his financial adviser Charles Ewert of embezzlement, he was attacked in a car park by a hired French mercenary swinging a rubber mallet, in an attempt staged to look like an accident. Glock was hit in the head but fought back, at nearly 70, and both men were convicted of attempted murder. He died on December 27, 2023, at 94, so the Gen 6 and V series are the first new lines of the post-founder era.

Glock sits in the value-to-mid tier and is proud of it. You aren’t paying for hand-fitting or a pretty finish. You’re paying for a gun that keeps working, and for the fact that everything in the gun store fits it.

Gen 6, V series and what it means for parts

This is the part most older Glock pages miss. Glock announced Gen 6 on December 6, 2025, with the G17, G19 and G45 in 9mm available from January 20, 2026. It has a palm swell, an extended thumb rest, an enlarged beavertail, a flat-faced trigger and three optic plates on standard models. The V series is the other half of the story, a refreshed baseline line including the G17 V, G19 V and G26 V. Gen 5 G17 and G19 pages have moved to Glock’s law enforcement section.

On the outside, Gen 5 and Gen 6 G17s share their published dimensions, so holsters and lights tend to carry over, though makers may still list each generation separately. Inside is where it breaks. The trigger housing, barrel and optic mount changed, so plenty of aftermarket drop-in kits, barrels and slides stop at Gen 5. Before you buy any internal part, look for your generation in the listing and trust the maker’s fit line over a retailer title.

California

California’s AB 1127, signed in October 2025, bans the commercial sale of Glock and Glock-style handguns from July 1, 2026. It doesn’t criminalize guns people already own. Second Amendment groups and the US Justice Department have both sued. If you live there, check where the case stands before you shop.

What Glock makes

The pistol line

The Glock 19 is probably the most recommended handgun in America, and a G19 Gen 6 was $597.60 at MidwayUSA and $620 at Brownells in our feed. The G17 Gen 6 was $595.28. The slim G43X was $448, and the G26, G34, G20 and G21 fill out the catalog. Note that several older models, such as the G29 and G30, have moved to the law enforcement catalog, so stock can be thin.

Factory magazines

If you buy one accessory, buy more factory mags. A G17 17-rounder was $24.95 at Optics Planet. Our best Glock magazines guide prices the options. Orange followers, speed loaders and mag catches are all a few dollars, and they’re in the carousel below.

Barrels, slides and small parts

OEM barrels start around $134 at Brownells. Be careful here, since many are labelled by generation, such as a G17 barrel marked Gen 1-4. Springs are about $7, a slide cover plate is under $4 and a connector about $3. These are cheap insurance on a carry gun. Glock’s own slide-lock springs, recoil springs and firing pin parts are the safe choice for anything that touches reliability.

Sights

This is the one place Glock is honestly weak. The factory polymer sights are functional and not much more, at about $4.31. Night sights cost about $83 from KYGUNCO, and dovetails haven’t changed across generations. Most serious owners replace the plastic on day one.

Build quality and where it is made

Glocks come from Austria and Smyrna, Georgia, and listings often say which. The hallmark is sameness, not craftsmanship. The frame is a nylon-based polymer and the steel gets a hardened nitrided finish, and every gun off the line is meant to be the same gun. Three automatic internal safeties, on the trigger, firing pin and drop, replace any manual lever, so holster discipline and trigger discipline matter on a Glock.

How Glock compares

The honest rivals are the Smith & Wesson M&P, the SIG P320 and the Walther PDP. The M&P and PDP arguably point more naturally and have better stock triggers, and the P320 is modular in a way a Glock isn’t. Where Glock wins is the ecosystem. Nobody else has decades of holsters, mags and sights built around one pattern. One caution: Gen 6 resets some of that advantage for internal parts, though not for holsters and sights.

Who should buy what

• Everyday carrier: a G19 Gen 6 and three or four factory mags.
• Deep-concealment carrier: a 43X or G26 V, with a holster made for it.
• Home-defense buyer: a G17 or G45 Gen 6 with a light and a dot.
• Competitor: a G34 with steel sights and a red dot.
• Owner of an older gun: factory springs, a firing pin and night sights.

If you want a tuned trigger out of the box or a thumb safety, look elsewhere.

The Glock philosophy

Gaston Glock was an outsider who didn’t know which rules he was supposed to respect. He used polymer where others used steel, dropped the manual safety and cut the parts count. The gun looks blocky because it was engineered, not styled, and that same idea runs through the parts: the fewest pieces that will do the job.

How to choose your Glock setup

Start with the frame size that fits your hand and how you carry. Then buy magazines until you have at least four. Replace the sights next. Keep a small kit on hand, such as springs and a connector, and learn to detail-strip the gun. If you own a Gen 6, read fit lines closely before you buy an aftermarket trigger kit, barrel or slide.

The plastic-gun myth

When the Glock 17 reached the US in the 1980s it set off a small panic about a gun that would sail through airport security. The myth contributed to the Undetectable Firearms Act of 1988, and Die Hard 2 made it famous in 1990 with a fictional porcelain “Glock 7.” It was nonsense. Most of a Glock’s weight is steel, and the polymer shows on an X-ray anyway.

What Glock owners upgrade

The first change for nearly every owner is the sights, then a better connector or trigger, an extended slide stop and a match or threaded barrel. A red dot is now just as common, on an optics-ready slide with suppressor-height sights. Baseplate extensions, grip tape and recoil springs round out the list.

Most of those upgrades come from aftermarket makers, so you won’t find all of them under the Glock name below. What you’ll find here are factory magazines, parts and sights. For aftermarket options, see our Glock guides.
