Chris Raper — Retired North Carolina law enforcement (40+ years) · U.S. Air Force Security Police · NRA-certified Pistol, Rifle & Shotgun Instructor · NC DOJ-certified Concealed Carry Instructor · Founder, Concealed Handgun Carry, Inc. (Elm City, NC, 2006)This guide draws on my own research and what my students bring into the Concealed Handgun Carry class every week. The method line at the end of the article says exactly how this guide was built.
Quick answer
For most people who carry every day, the Glock 19 is the better pick: it is about two-thirds of an inch shorter, about four-tenths of an inch shorter in the grip, and still holds 15 rounds of 9mm. Choose the Glock 17 if the gun will live mostly on a nightstand, in a duty holster or on an outside-the-waistband belt rig, or if you have big hands and want the longer sight radius and two extra rounds.
The Glock 17 and Glock 19 are the same pistol in two sizes. Same 9mm cartridge, same Safe Action trigger, same controls, same takedown, same 1.34-inch overall width. What changes is length, grip height, capacity and a little weight. Those small numbers are what decide whether a gun gets carried every day or stays in the safe, so they are worth going through one at a time.
Students in my North Carolina concealed handgun class ask me about these two more than any other pair. The ones who choose well do not start with which gun is “better.” They start with where the gun will ride, what they wear, and how big their hands are. That is the order this guide follows. Specifications below come from GLOCK’s published data; check the current listing for the exact model you buy.

Concealment: the grip prints, not the slide
GRIP HEIGHT:
The number most people look at is overall length, but the number that decides whether a gun shows through a shirt is grip height. The Glock 19 is 5.04 inches tall with the magazine in. The Glock 17 is 5.47 inches. That extra four-tenths of an inch is all in the butt of the gun, and the butt is the part that pushes against your shirt when you bend over, reach for something on a shelf or buckle a seat belt. If printing is your problem, start with our guide on how to stop printing before you decide the gun is too big.
SLIDE AND BARREL LENGTH:
Below the belt, slide length matters less than people expect. A longer barrel tucked inside the waistband is mostly hidden by your pants. Where the G17’s extra length shows up is comfort when you sit, especially in the appendix position, where the muzzle end of the holster can dig into your thigh. If you carry appendix, read our appendix carry guide and try sitting in a car seat with a holstered, unloaded gun before you buy anything.
WEIGHT:
Empty, GLOCK lists the two at the same weight with a magazine in place. Loaded, the 17 carries about an ounce more because of the two extra rounds. Neither is a light gun. Both need a real gun belt to ride well all day, which is why I tell every class that the belt is part of the gun purchase. Our gun belt guide explains what to look for.
Shooting: what the extra half inch buys you
SIGHT RADIUS:
The G17’s sights sit about half an inch farther apart than the G19’s: 6.50 inches against 6.02 with the factory polymer sights. A longer sight radius makes small alignment errors easier to see, which helps on longer, slower shots. At the distances most defensive shootings happen, the difference is hard to measure. Where new shooters notice it is during qualification, when they are trying to tighten a group.
RECOIL AND MUZZLE RISE:
Same cartridge, nearly the same weight, so recoil is close. The 17’s extra slide and barrel length put a little more weight out front, which some shooters feel as a flatter, slightly calmer muzzle. The difference is small enough that the honest way to judge it is to rent both and shoot them side by side. Both are among the easier 9mm carry guns to shoot well; if recoil is your main concern, compare them with the options in our guide to concealed carry guns with the least recoil.
GRIP AND HAND SIZE:
This is where the decision gets personal. On the G17, a large hand gets all fingers on the grip with room to spare. On the G19, the pinky usually lands on the bottom edge of the magazine floorplate or just under it for people with big hands. Small and medium hands usually fit the G19 completely and feel the G17 as long rather than better. Both frames take interchangeable backstraps, so try them with the backstrap that fits you, not the one that came in the box.
Capacity and magazines
The G17 ships with 17-round magazines and the G19 with 15-round magazines. Two rounds is a real difference on paper and a small one in practice. Trainers who track armed-citizen shootings report mostly short exchanges with few rounds fired, which is why I put concealability and the ability to hit ahead of capacity for a carry gun.
The useful part is that magazines go one direction. GLOCK lists 17 rounds as an optional capacity for the G19, which means a G17 magazine works in a G19, with the extra length sticking out below the grip. Many people carry a G19 and keep G17 magazines as spares, or keep a G17 magazine in the gun at home. Going the other way, a short G19 magazine in a G17 frame is not a setup I would carry. Whatever you choose, check that your state allows the magazine capacity you want; a few states restrict it.
Holsters, lights and optics
HOLSTERS:
Because the two frames share width and controls, many holster makers mold one holster that fits both, with an open bottom that lets the G17’s longer slide pass through. Others mold a specific holster for each. Read the maker’s fit list rather than assuming, and make sure the holster covers the trigger guard completely. Our concealed carry holster guide and IWB vs OWB comparison cover the basics, and holster retention levels explains what a duty-style holster adds.
OPTICS AND SIGHTS:
Both models are offered in optic-ready versions, and the newer Gen6 models are described by GLOCK as optic-ready out of the box. If you plan to swap iron sights instead, the job is the same on both slides; our best sight pusher for Glock guide covers the tools that do it without marring the slide.
LIGHTS:
Both frames have the same accessory rail. A weapon light adds length and changes which holster you can use, so pick the light and the holster together.
What about the GLOCK V models and Gen6?
In October 2025 GLOCK announced it was retiring most of its commercial lineup and replacing it with “V” models, including the G17 V and G19 V. GLOCK said the guns would keep the same look and performance, and that it would continue servicing earlier generations. GLOCK has since added Gen6 versions of the 17 and 19 with a palm swell, a thumb rest, a new grip texture, a flat-faced trigger and an optic-ready slide.
For this comparison, the important point is that the size relationship did not change. On GLOCK’s published data the G17 Gen6 and G19 Gen6 keep the same overall lengths, slide lengths and heights as the V models. The Gen6 pages list slightly different weights and a shorter trigger reach, so if you are choosing between generations, hold both. If you are buying used, Gen3, Gen4 and Gen5 guns follow the same 17-versus-19 size pattern.
Which one should you buy?
- Buy the Glock 19 if this is your daily carry gun, you carry inside the waistband, you sit a lot or drive for work, or you have small to medium hands. It is the more forgiving size for concealment and still a full-capacity, easy-shooting 9mm.
- Buy the Glock 17 if the gun will mostly guard the house, ride in an outside-the-waistband or duty holster, or serve as a range and competition gun. Big hands and anyone who wants the longest sight radius will also like it.
- Buy the 19 and carry 17 magazines as spares if you want one gun that does both jobs reasonably well.
If neither fits, look smaller. Our best micro-compact 9mm, compact vs subcompact vs micro-compact and best Glock for concealed carry guides cover the G43X, G48 and the rest of the family.
HOW TO DECIDE AT THE GUN SHOP:
- Hold both with the backstrap that fits your hand. Note where your pinky lands.
- Ask to see each in a holster on your own belt, under the shirt you actually wear. Bend, sit and reach.
- Rent both at a range if you can. Shoot the same drill with each and compare hits, not feelings.
- Price the holster, belt and two spare magazines with the gun. That is the real cost.
Key takeaway: the Glock 19 hides more easily because its grip is shorter; the Glock 17 is a little easier to shoot well and holds two more rounds. Pick the one you will carry every day.
Glock 17 vs Glock 19 FAQ
Is the Glock 19 good for concealed carry?
Yes. It is one of the most commonly carried full-capacity 9mm pistols because its 5.04-inch grip height and 7.28-inch length hide well inside the waistband while still holding 15 rounds.
Can you conceal a Glock 17?
Many people do, especially inside the waistband with a good belt and a cover garment. The longer grip is harder to hide than the slide, so pay attention to holster cant and ride height.
Will Glock 17 magazines work in a Glock 19?
Yes. GLOCK lists 17 rounds as an optional capacity for the G19, so a G17 magazine fits and functions, with the extra length extending below the grip.
Which is more accurate, the Glock 17 or the Glock 19?
Mechanically they are very close. The G17’s longer sight radius makes aiming errors easier to see, which helps some shooters on longer shots.
Do the Glock 17 and 19 use the same holster?
Some holsters are made to fit both, usually with an open bottom. Always check the holster maker’s fit list for your exact model and any light or optic.
