Glock 19: the complete guide before you buy
Published on · Updated on · 8 min read · Anthony Baillon
The Glock 19 is the compact 9mm every other manufacturer measures itself against, and the one most often recommended without reservation. Here is what it genuinely does well, where it gives ground, and how it compares with the range pistols in this series.
At a glance
| Glock 19 Gen5 | |
|---|---|
| Weight | 670 g with empty magazine, 855 g loaded |
| Barrel | 102 mm, or 4.02 inches |
| Capacity | 15 + 1 rounds of 9 × 19 |
| Trigger | 26 N listed, about 2,650 g |
| French category | B: authorization required |
| Price | €722 new, €549 used |
- Its argument: nothing disqualifies it, whatever the use.
- Its weakness: the factory trigger, the heaviest of the 9mm pistols compared here.
- For an optic: the MOS version, cut at the factory, almost always costs less than a conversion.
Glock 19: pros and cons
Pros
Glock 19: rarely the best, never ruled out
The Glock 19 is rarely the best pistol for any given task. It is also rarely a poor choice, whatever the task, and that is the whole argument.
At 670 grams with an empty magazine, a 102 mm (4.02-inch) barrel and 15 rounds1, it sits at the point where nothing disqualifies it: small enough to transport without organizing your day around it, large enough to shoot well with a full firing grip.
The clearest evidence is not in any review but in the market. Enough manufacturers have built pistols to these dimensions that "Glock 19 size" now describes a category rather than a brand.
Glock 19 size: 670 g, half a range pistol
The Glock 19 against full-size range 9mm pistols
Unloaded weight without magazine; the Glock 19 is a compact, and the comparison shows what that format brings and what it costs
Every figure is the manufacturer's own, magazine empty. This chart does not rank the Glock 19 among range pistols — it is not competing with them. It shows the price of compactness: roughly half the mass of a steel competition pistol, and everything that follows from it.
View the data
| Pistol | Unloaded weight | Barrel | Capacity | Use |
|---|---|---|---|---|
| CZ Shadow 2 | 1,330 g (46.9 oz) | 4.7" | 19 + 1 | Range |
| Walther PDP Steel Frame Match 5" | 1,195 g | 5" | 18 or 20 | Range |
| Staccato P | 936 g (33 oz) | 4.4" | 17 + 1 or 20 + 1 | Range and duty |
| Glock 34 Gen5 MOS | 743 g (26.21 oz) | 5.31" | 17 + 1 | Competition |
| Glock 19 Gen5 MOS | 670 g (23.63 oz) | 4.02" | 15 + 1 | General purpose |
Set against the range pistols in this series, the Glock 19 weighs roughly half what a steel competition pistol does — 670 grams1 against the 1,330 CZ lists for a Shadow 26. That is not a criticism — they are not competing for the same use — but it deserves to be seen clearly, because everything else follows from it.
What you gain: a light pistol, easy to take to the range, that needs no planning.
What you give up: the mass that steadies a pistol between shots, and 33 millimeters of barrel against a Glock 34 — which Glock's own sheets turn into 38 millimeters of sight radius, 153 against 19112. On deliberate shots at distance, it shows.
The Glock 19 is a general-purpose pistol that shoots well, not a range pistol that happens to be easy to transport. Bought for the first of those two descriptions, it will not disappoint.
Glock 19 trigger: 26 N, its weakest point
Trigger pull, in grams
Manufacturers' figures; the table view also gives newtons and a press measurement of the Glock 19
The Glock 19 trigger is not a competition trigger, and does not claim to be. The comparison sets expectations: a shooter moving from this pistol to a range pistol will find a very different break, and the reverse holds too.
View the data
| Pistol | Grams | Newtons | Nature of the figure |
|---|---|---|---|
| Staccato XC | 1,134 g | 11.1 N | manufacturer, 2.5 lb |
| CZ Shadow 2, single action | 1,530 g | 15 N | manufacturer |
| Glock 34 Gen5 | 2,447 g | 24 N | manufacturer |
| Walther PDP | 2,500 g | 24.5 N | manufacturer |
| Glock 19 Gen5 | 2,651 g | 26 N | manufacturer |
| Glock 19 Gen5 | 2,637 g | 25.8 N | review measurement, 5 lb 13 oz |
This is where the platform gives the most ground.
Glock publishes the figure in newtons, as European manufacturers do: 26 newtons1, about 2,651 grams. An independent measurement of a Gen5 MOS put the break at 5 pounds 13 ounces12, or 2,637 grams: within an ounce of the listed figure, which is rarer than it sounds. That is heavier than the 24 newtons listed for the Glock 342 and the 2,500 grams listed for a Walther PDP8, and well above what a range pistol offers: CZ lists 15 newtons, or 1,530 grams, for a Shadow 2 in single action6, Staccato 1,134 grams for an XC1014.
No rulebook makes you live with it. USPSA states that "there is no restriction on the trigger pull weight of a firearm" outside the divisions that set a threshold4; IPSC Production is one of the few that does, at 2,270 g on the first shot or 1,360 g on every shot5.
In return, the break is identical from the first shot to the last, with no double-action first pull to learn — the trade-off our trigger guide sets out in full.
A technical warning before having yours lightened: it is gunsmith work, to be validated on the ammunition you actually shoot — Glock's own manual treats a firing-pin indent that is too light or off-center as a reason to stop and consult a gunsmith3.
Glock 19 reliability: four causes of malfunction, per Glock
Glock's instructions are blunt about where malfunctions come from, and the list does not point at the pistol: an incorrect grip, unsuitable cleaning or lubrication, a damaged magazine, or ammunition outside SAAMI, CIP or NATO standards3. The 9mm Luger those standards define is a 35,000 psi cartridge, with a 9.030 mm (.3555-inch) bullet11.
For a buyer, the question is therefore mostly about grip angle and trigger — two points settled in the hand, not on a spec sheet.
Glock 19 optics: the MOS version over a conversion
MOS versions are cut at the factory for a red dot1 and accept most optics on the market through a set of adapter plates. Non-MOS versions need slide milling at a specialist.
The division comes before the optic. In USPSA, Carry Optics and Limited Optics both require the optic to be attached directly to the slide, never to the frame; USPSA Production and IPSC Production both forbid optical sights outright45.
If an optic is part of the plan, buying the MOS version from the start almost always costs less than converting a standard slide later, and it avoids weeks with the pistol out of service. Our red dot guide covers footprints, plates and the full cost.
Glock parts: a huge market, and one trap
The Glock parts market has no equivalent: triggers, barrels, sights, flared magwells, magazine base pads, compensators.
That breadth is a real advantage: you can adapt the pistol to your hand and your discipline over time, spreading the cost. It is also a trap, because some of those parts close a division: USPSA Production and Carry Optics forbid compensators and ported barrels, and IPSC Production bans every non-factory part except magazines, open sights, grip panels, springs, hammers and trigger assemblies45.
One modification at a time, at a gunsmith, making sure the pistol runs before moving on to the next.
Glock 19, Glock 34, Walther PDP: what sets them apart
- Against a Glock 34: same platform, different use. The 34 adds sight radius, two rounds and competition details; the 19, ease of transport.
- Against a Walther PDP: same striker-fired family. Walther lists a 2,500-gram break across the whole range, slightly under the Glock 19's 26 N, and its 5-inch polymer Full Size, at 745 grams8, competes more with the Glock 34 than with the 19.
- Against a CZ Shadow 2 or a Staccato: the comparison is not a fair one. These are dedicated range pistols: 1,330 grams of steel for the CZ6, 936 for a Staccato P913, against a steel-framed Walther Match at 1,1957. The Glock 19 is not trying to be one.
Our comparison of eleven competition 9mm pistols covers the range pistols proper.
Glock 19 budget: €624 of ammunition a year
| Item | Amount |
|---|---|
| Glock 19 Gen5, new | €72216 |
| Glock 19 Gen5, used | €54917 |
| Gun safe, for a first category B firearm | €115 to €2891920 |
| 9mm ammunition, at 200 rounds a month | €624 a year18 |
With a new Glock 19, the first year comes to about €1,460 to €1,640, before license and club fees; in the following years, ammunition remains the main item, at €624 a year. For the identical version, the used pistol found on the same day costs 24% less than new1617.
Depending on use, the list grows with spare magazines — Glock offers 15, 17, 24, 31 and 33 rounds for this frame1, covered in our magazine guide —, an optic plate on a MOS version, more visible sights, and sometimes the trigger.
In France, the Glock 19 is a Category B firearm, like every centerfire pistol: a sport shooter needs a prefectural authorization to buy one, and must store it in a gun safe, a strong cabinet or a strongroom2122. The route from license to purchase is set out in our guide to the French Category B authorization.
Buying a Glock 19: who it suits, and who less
What it brings, and what it asks
It suits a shooter who wants a single pistol for almost everything: range practice, a first competition season, a light pistol to transport. Its reliability removes a whole category of worries, and its parts market lets it evolve.
It suits less a range shooter chasing scores: the sight radius and mass of a dedicated competition pistol make themselves felt. Less, too, anyone the brand's grip angle has never convinced — a criterion settled in the hand.

Generation and version change the spec sheet. Glock 19s come in several generations whose grips, textures and optic provisions differ, and MOS and non-MOS slides are not interchangeable in this respect. Any work on the trigger is a gunsmith's job, as Glock's manual points out for any abnormal firing-pin indent.
Frequently asked questions
Why is the Glock 19 so often recommended?
Because it sits at the point where nothing disqualifies it. At 670 grams with an empty magazine, with a 102 mm (4.02-inch) barrel and 15 rounds, it is small enough to transport without fuss and large enough to shoot well. It is rarely the best pistol for any given task, and rarely a poor choice, whatever the task.
Glock 19 or Glock 34?
Two different uses. The 34 adds a longer barrel and 38 millimeters of sight radius, 17 rounds and competition-oriented details, for 73 grams more and a size that no longer goes unnoticed. The 19 gives up sight radius and two rounds for a pistol you transport without organizing anything around it. For scoring at the range, the 34 is the better-suited tool; for a lighter, shorter pistol, it is the 19.
What is the Glock 19 trigger worth?
It is the platform's weakest point. Glock lists 26 newtons, about 2,651 grams or 5.85 pounds, and an independent measurement of a Gen5 MOS gave 5 pounds 13 ounces — the two figures agree within an ounce, and both sit above the 24 newtons Glock lists for the 34, as well as the 2,500 grams Walther lists for the PDP. The parts market is considerable; any work on the trigger is a gunsmith's job.
Does the Glock 19 take a red dot?
MOS versions leave the factory with the optic cut and accept most optics through a set of adapter plates, with no slide milling. Non-MOS versions need milling at a specialist. If an optic is part of the plan, buying the MOS version from the start almost always costs less than a later conversion.
Is the Glock 19 reliable?
Glock ties malfunctions to causes outside the pistol: an incorrect grip, unsuitable cleaning or lubrication, a damaged magazine, or ammunition outside SAAMI, CIP or NATO standards. A firing-pin indent that is too light or off-center, on the other hand, sends the pistol to a gunsmith.
Do you need an authorization to buy a Glock 19 in France?
Yes. Like every centerfire pistol, the Glock 19 is a category B firearm under French law: a sport shooter can only buy one with an authorization from the prefect, applied for online after three supervised shooting sessions. Four to seven months usually pass between the license and the purchase, and the pistol must then be stored in a gun safe, a strong cabinet or a strongroom.
