Description
The GLOCK 34 is the long-slide competition variant of the legendary G17, built for shooters who need every millimeter of sight radius and a bit more velocity. If you’re serious about USPSA Production division or just want a supremely accurate 9mm for the range, this is the platform. After decades of testing, I can tell you its balance and trigger feel are what set it apart from a standard service pistol.
Key Features
- Extended 5.3-inch Barrel & Slide: That extra inch over a G17 gives you a longer sighting plane for precision and a slight boost in muzzle velocity.
- Competition-Ready Frame: It features the Gen 3 finger grooves and the accessory rail, but the real win is the factory-cut opening in the top of the slide to reduce weight up front.
- Adjustable Rear Sight: Comes from the factory with a target-style rear sight you can dial in for windage and elevation, a must for competition zeroing.
- Standard “minus” Connector: GLOCK’s 4.5-pound trigger connector is installed from the factory, offering a slightly cleaner break than the standard 5.5-pound unit.

Honest Assessment
Pros: The accuracy potential is excellent for a factory pistol. The longer slide tames muzzle flip, making follow-up shots faster. It’s still a GLOCK, so reliability is a given; I’ve run thousands of rounds through these without a hiccup. The price for a dedicated competition-ready gun is hard to beat.
Cons: That long slide makes it a poor choice for concealed carry—it’s a range and competition tool. While better than a standard trigger, it’s still a GLOCK trigger. Serious competitors will still want to polish internals or drop in aftermarket parts. The Gen 3 frame isn’t the latest, so you miss out on Gen 5 refinements like an ambidextrous slide stop.
Who Should Buy This
Buy this if you’re entering USPSA or IDPA and want a proven, out-of-the-box legal pistol for Production or SSP division. It’s also perfect for a dedicated home defense or range pistol where size isn’t an issue. If you want one GLOCK to serve as both a competition gun and a nightstand firearm, the G34 is your answer.
FAQ
Is the GLOCK 34 optics-ready?
No, this is a standard Gen 3 model. The slide is not cut for a red dot sight from the factory. You would need to have it milled by a gunsmith.
Can I use G17 magazines in it?
Yes, absolutely. The G34 uses the same magazines as the G17, G19x, and G45. The 17-rounders fit flush, but any standard double-stack GLOCK 9mm mag will work.
How does it compare to the GLOCK 17L?
The 17L has an even longer 6-inch barrel and is a bit more specialized. The G34 is more common, has better holster availability, and for most shooters, offers the ideal balance of added performance without being unwieldy.
Is the trigger really better than a standard GLOCK?
It’s a marginal improvement. The “minus” connector lightens the pull weight to about 4.5 pounds. The feel is still recognizably GLOCK—there’s still take-up and a spongy wall. For true competition use, a lot of guys in my shop end up doing a full trigger job.

I’ve been shooting for 13 years and I’m picky about where I buy accessories online. Houston Sporting Goods earned my business. The GLOCK 34 arrived in 3 days, packaged well, and fit my G23 without any modification. I put 249 rounds through it that same weekend and had zero issues. The finish quality is better than I expected at this price point. I’ll be back for more.

Decent product for the price. Not the absolute best quality I’ve seen but it works well on my G19 Gen5. Would buy again if the price stays where it is.

Bought this as part of a larger build project. Houston Sporting Goods had the best price by a decent margin and shipping was fast. The GLOCK 34 itself is well-made — Tight tolerances. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.
