Glock 34: the complete guide before you buy
Published on · 17 min read · Anthony Baillon
The Glock 34 is the pistol many shooters enter competition with: 743 grams, a 5.31-inch barrel1, and a reliability record that stopped being argued about long ago. Here is what it offers, what draws criticism, and how it sits against heavier range guns.
Why the Glock 34 works as a way into competition
One reviewer who used one in competition for years sums up his reasoning in three words, and the order matters: light, simple, reliable.
This is not the pistol that wins on a spec sheet. It is the one that asks least of you to start: it costs a fraction of a 2011, strips in seconds without tools, and its maintenance amounts to a routine. For someone taking up a discipline without knowing yet whether they will stay with it, that is a serious argument.
It also carries the longest barrel in this comparison — 135 millimeters, or 5.31 inches, for a sight radius Glock puts at 191 millimeters1 — and therefore the longest sight radius, which is more forgiving of alignment error.
The Glock 34's light weight, and its flip side
This is its most defining characteristic, and it cuts both ways.
The Glock 34 against competition 9mm pistols
Manufacturer weight without magazine; the Glock 34 sits among the lightest of its competition class
Every figure here is read off the maker's own specification sheet, magazine empty, except the Beretta, whose weight is a review measurement. That lightness is a design choice, not a shortcoming — but it has a flip side. The 587 grams separating the Glock 34 from a CZ Shadow 2 are 587 grams not available to soak up recoil and slow muzzle rise between shots.

| Pistol | Weight | Frame | Barrel | Capacity |
|---|---|---|---|---|
| Beretta 92X Performance | 1,350 g (47.61 oz) | Steel | 4.9" | 15 |
| CZ Shadow 2 | 1,330 g (46.9 oz) | Steel | 4.7" (120 mm) | 19 + 1 |
| Walther PDP Steel Frame Match 5" | 1,162 g (41 oz) | Machined steel | 5" | 20 |
| Staccato P | 936 g (33 oz) | 4140 steel | 4.4" | 17 + 1 or 20 + 1 |
| Walther PDP Match Full Size 5" | 766 g (27 oz) | Polymer | 5" | 18 |
| Glock 34 Gen5 MOS | 743 g (26.21 oz) | Polymer | 5.31" (135 mm) | 17 + 1 |
At 743 grams1, the Glock 34 sits 587 grams below a CZ Shadow 25 and 419 below a steel-framed Walther PDP7. It is the lightest gun in this comparison, a polymer PDP Match included8.
What that buys you: a pistol you carry without thinking, lend easily, and that tires you less across a long standing session.
What it costs: absent mass does no work. On a range gun, mass is what soaks up recoil and slows muzzle rise between shots. The Glock 34 climbs more than a steel gun of the same length, and you make that up with technique or a compensator.
The Glock 34 trigger, its most debated feature
This is where opinion divides most, and it deserves precise numbers.
Glock 34 trigger pull: listed, and measured by owners
In pounds, grams and newtons; manufacturers publish in newtons, reviewers measure in pounds, and both are given here
Glock and CZ publish trigger pull in newtons on their specification sheets; Staccato publishes in pounds; the Walther figure is a review measurement, no pull weight being listed. This is the most debated aspect of the pistol. The factory figure already places it above its range-oriented rivals, and several owner gauge readings come in higher still. It is exactly what aftermarket trigger parts exist to address.
Voir les données
| Pistol | Pounds | Grams | Newtons | Nature of the figure |
|---|---|---|---|---|
| Staccato XC | 2.5 lb | 1,134 g | 11.1 N | manufacturer |
| CZ Shadow 2, single action | 3.4 lb | 1,530 g | 15 N | manufacturer |
| Walther PDP Steel Frame Match | 4 lb 12 oz | 2,155 g | 21.1 N | review measurement |
| Glock 34 Gen5 | 5.4 lb | 2,447 g | 24 N | manufacturer |
| Glock 34 Gen5 | 6.75 to 7.25 lb | 3,062 to 3,289 g | 30.0 to 32.2 N | owner gauge readings |
Glock publishes the figure in newtons, as European makers do: 24 newtons1, which is 2,447 grams, or 5.4 pounds. But several owner gauge readings come in considerably higher — up to 6.75 or 7.25 pounds depending on the example16, meaning 3,062 to 3,289 grams.
The gap against range guns is clear: CZ lists 15 newtons — 1,530 grams — for a Shadow 2 in single action5, Staccato 2.5 pounds for an XC10. The Glock starts from much higher, and in exchange gives you an identical break from first shot to last, with no double-action first pull to learn.
Neither USPSA nor IPSC sets a floor that would stop you lightening it: USPSA states plainly that "there is no restriction on the trigger pull weight of a firearm" outside the divisions that impose one3. IPSC Production is one of those, at 2,270 grams on the first shot or 1,360 grams on every shot4 — and the Glock 34 is excluded from that division anyway, its 135-millimeter barrel exceeding the 127-millimeter ceiling.
One technical point before you have yours lightened: reducing pull weight too far on a striker-fired pistol reduces striker energy, which can cause light primer strikes and disrupt cycling17. This is gunsmith work, not kitchen-table work. Glock's own manual lists a light or off-center firing-pin indent among the reasons to hand the pistol to a gunsmith rather than fire it again2.
Reliability, the argument nobody contests
If one point commands unanimity on this platform, it is this one.
Reviews report thousands of rounds without incident — one reviewer citing over a thousand on one example and thousands more on earlier ones. Another logs seven hundred rounds across varied ammunition with no stoppages17. The recurring formulation, in substance: it would take a major failure to make this pistol unreliable.
Glock's own instructions name what does cause stoppages, and it is rarely the gun: an improper grip, improper cleaning or lubrication, a damaged magazine, and ammunition outside SAAMI, CIP or NATO standards2. The 9 mm Luger those standards define is a 35,000 psi cartridge with a .3555-inch bullet11.
For a club shooter that shifts the question. The issue is not whether the gun will hold up, but whether its ergonomics and trigger suit you.
Ergonomics: grip angle and texture
Two reservations recur, and neither is disqualifying.
The grip angle is the brand's signature, and it does not suit everyone. A shooter used to another architecture notices it immediately — a criterion you test in the hand, not on a spec sheet.
Texture is the more frequent complaint on older generations: one reviewer finds it insufficient and prefers what several rivals offer17. Recent generations have improved, and a large share of owners add grip tape or have the frame stippled regardless.
Against that sits an advantage reviewers acknowledge: these pistols are easy to fit to your hand, precisely because the parts market is vast.
Optics: the MOS system from the factory
Here the Glock 34 is ahead of several rivals. MOS versions are factory-prepared for a red dot1, and one reviewer notes they accept most optics on the market through a set of plates17.
Where a Beretta 92X Performance requires slide milling, the Glock needs a plate and screws. For a shooter heading into an optics division, that is a cost and a delay avoided — our red dot guide covers footprints and what the whole thing runs to.
Read the division rules before you buy the glass. USPSA Carry Optics and Limited Optics both require the sight to be attached directly to the slide, between the rear of the slide and the ejection port, forbid frame mounts, and cap magazines at 141.25 millimeters; Carry Optics adds a 59-ounce ceiling with the optic and an empty magazine fitted3. IPSC takes the opposite tack across two divisions — Production bans optical sights, Production Optics requires one4.
The parts ecosystem, its real strength
This is what genuinely sets the platform apart, and it is worth understanding before buying.
The parts market has no equal: triggers, barrels, compensators, flared magwells, fiber optic sights, extended base pads. One reviewer notes that a worked-over Glock has little in common with the gun out of the box, and that ready-built versions now exist for those who would rather not fit parts themselves17.
Some of those parts close a division to you. USPSA Production and Carry Optics both forbid compensators and barrel ports, and Production restricts you to the models on its approved list3; IPSC Production goes further and bans aftermarket parts outright, bar magazines, open sights, grip panels, springs, hammers and trigger assemblies4.
One caveat from the same reviewer: accumulating parts from various sources that were never designed to work together is the surest way to create problems17. One modification at a time, at a gunsmith, confirming the pistol still runs before moving on.
The Glock 34 against its rivals
- Against a CZ Shadow 2 — you trade 587 grams of steel5 and a single action CZ lists at 15 newtons against 241, for handling, simpler maintenance and a lower price.
- Against a Walther PDP — same technical family, striker-fired. A Steel Frame Match measured 4 pounds 12 ounces in test13; they separate on ergonomics and factory trigger, where reviewers generally place the PDP ahead.
- Against a 2011 — the trigger gap is wide, and so is the price gap: Staccato lists a P at $2,4999. The Glock is the starting point, the 2011 the destination for those who go there.
- Against a Beretta 92X Performance — opposing mechanisms, single pull against double/single action, and 607 grams between them12.
Our comparison of eleven competition 9mm pistols places these side by side across every criterion.
What a Glock 34 really costs
The purchase price is the lowest in this comparison, but the spending does not stop there:
- Two or three spare magazines, with base pads if you compete — see our magazine guide. Check the length before you buy: USPSA caps Carry Optics and Limited Optics magazines at 141.25 millimeters, measured on an EGW gauge3.
- An optic plate, if you mount a red dot on a MOS version.
- Sights, often swapped for a fiber optic front.
- Possibly the trigger, the most common modification on this pistol.
- Ammunition, the dominant cost over time.
Purchase requirements, permits and magazine capacity limits are set at federal, state and sometimes local level in the United States, and differ substantially between states. Check what applies where you live before ordering.
Should you buy a Glock 34?
It suits a shooter entering competition without wanting to commit the budget of a dedicated range gun straight away, who wants a mechanism that is simple to maintain, and who accepts working on the trigger later if the need arises.
It suits less well someone whose practice is purely static and who wants maximum stability: at that game, the extra 587 grams of steel in a Shadow 2 tell5. And it suits less well a shooter the brand's grip angle has never convinced — that is not something you argue yourself out of.
The Glock 34 in four lines
- Its strength: reliability nobody disputes, and the widest parts market available.
- Its weakness: the factory trigger, the heaviest in this comparison.
- Its trade-off: 743 grams, so easy to handle and less settled when shooting.
- Its hidden advantage: the MOS slide takes a red dot without milling.

Check the generation and the version. Glock 34s come in several generations whose grips, textures and optic mounting systems differ substantially, and spec sheets are easily mixed up online. Any trigger work is gunsmith territory: an over-lightened striker trigger reduces striker energy and can cause light primer strikes. Division eligibility is decided by your match director, and purchase requirements and magazine capacity limits differ by state.
Frequently asked questions
Is the Glock 34 a good competition pistol?
It is a recognized way in. One reviewer explains having used one in competition for years, for three reasons he lists in that order: light weight, simplicity and reliability. It will not match a 2011 on factory trigger pull, but it costs a fraction as much and takes modification readily. Plenty of shooters start here before deciding whether to invest further.
What is the real trigger pull weight of a Glock 34?
Glock publishes 24 newtons on its own specification sheet — 2,447 grams, or 5.4 pounds. Several owner gauge readings come in considerably higher, up to 6.75 or 7.25 pounds depending on the example, meaning 3,062 to 3,289 grams. If the number matters to you, measure your own: it is the only way to know what your pistol actually does.
Should you replace a Glock 34 trigger?
Not necessarily, but it is the most common modification on this pistol and the parts market is enormous. One caution matters: lightening a striker-fired trigger too far reduces striker energy and can cause light primer strikes, especially on hard-primer ammunition. Have the work done by a gunsmith and validate it on the ammunition you actually shoot.
Glock 34 or CZ Shadow 2?
Two philosophies. The Glock weighs 743 grams against the 1,330 CZ lists, carries without thinking about it, strips in seconds and costs noticeably less. The CZ brings 587 grams of steel that soak up recoil and slow muzzle rise, plus a single-action trigger CZ lists at 15 newtons against the Glock's 24. If the gun only ever sees the range, the CZ's stability advantage is real. If it also travels or gets loaned out, the calculation changes.
Does the Glock 34 take a red dot?
Yes — MOS versions are factory-prepared and accept most optics on the market through a set of plates. It is one area where this pistol is ahead of several rivals that require slide milling. Confirm your division before fitting one: USPSA Carry Optics and Limited Optics require the optic to be attached directly to the slide, while IPSC Production and USPSA Production forbid optical sights outright.
