Why This GLOCK 34 GEN 5 Belongs in Your Range Bag
I’ve built and shot more Glocks than I can count, from duty guns to full-race competition models. The GLOCK 34 GEN 5 stands out because it takes the legendary reliability of the platform and optimizes it for performance. That extended Glock 34 Gen 5 barrel length (5.31 inches) isn’t just for looks—it gives you a smoother recoil impulse and a longer sight radius that makes hitting targets at distance feel almost effortless. I’ve used this model as a base for several competition builds, and the out-of-the-box trigger and ergonomics are a massive leap forward from previous generations.

The Good and The (Honest) Considerations
What I like about it:
- ✅ The longer Glock 34 Gen 5 slide and barrel provide a tangible accuracy and recoil control advantage, especially for new shooters learning fundamentals.
- ✅ The Gen 5 marksman barrel is noticeably more accurate than previous generations right out of the box.
- ✅ No finger grooves and the ambidextrous slide stop make it comfortable for a wider variety of hand sizes.
- ✅ Flawless reliability. I’ve run thousands of rounds through these in training classes without a single malfunction attributable to the gun.
- ✅ The platform is a tinkerer’s dream. Want a Glock 34 Gen 5 threaded barrel or to convert it to a Glock 34 Gen 5 MOS for optics? The aftermarket has you covered.
A few things to know:
- ❌ Its size makes concealed carry impractical for most people. This is a duty, home defense, or competition pistol first. If you need a carry gun, see our compact handguns like the GLOCK 19.
- ❌ Some shooters debate Glock 34 Gen 5 vs Glock 17. The G17 is more versatile for holster compatibility and is a true ‘do-everything’ size. The G34 is a specialist.
- ❌ While rare, some users online report Glock 34 Gen 5 problems with early magazine followers. Glock resolved this, and all our inventory has the updated parts.
Who This Pistol Is For (And Who Might Look Elsewhere)
Buy it if: You’re getting into USPSA or IDPA competition and want a proven, reliable platform to start with. You’re a home defender who values extreme reliability and the ballistic advantage of a longer barrel. You’re a Glock enthusiast who wants the pinnacle of their full-size, performance-oriented line. You want a pistol you can customize over time with endless aftermarket parts.
Skip it if: Your primary need is concealed carry—it’s simply too large. You’re on an extremely tight budget and need a firearm for basic utility; a standard G17 or a reliable used pistol may be a better fit. You absolutely must have an optics-ready slide from the factory; you’d need the MOS version or to have the slide milled. Browse our optics-ready models here.
Common Questions About the GLOCK 34 GEN 5
Where can I buy a GLOCK 34 GEN 5 online?
You can purchase the GLOCK 34 GEN 5 right here at Californiagunshop (californiagunshop.com). We are a licensed retailer based in San Antonio, TX, and we ship to your local FFL dealer for a smooth, legal transfer.
How do I disassemble a GLOCK 34 GEN 5 for cleaning?
It’s the same simple process as any Glock. Ensure the gun is unloaded. Pull the trigger to de-cock it. Pull down slightly on the two slide lock tabs on either side of the frame while pulling the slide forward off the frame. The recoil spring assembly and barrel can then be lifted out. No tools needed.
How do I clean my GLOCK 34 GEN 5?
After disassembly, I use a quality solvent on the barrel, slide, and breech face, followed by a brush. Wipe everything down, apply a light coat of lubricant to the rail grooves, barrel hood, and connector area. Avoid over-lubricating. A clean Glock is a happy Glock—I do a basic clean every 500-1000 rounds.
What’s the difference between the GLOCK 34 GEN 5 and the MOS version?
The Glock 34 Gen 5 MOS comes from the factory with a slide cut and adapter plates to mount popular micro red dot sights (like Trijicon RMR, Holosun, etc.). The standard Gen 5 model reviewed here has a plain slide. The MOS is great if you know you want an optic; otherwise, you can have any gunsmith mill your slide later for a specific optic.
Can I use a threaded barrel on the GLOCK 34 GEN 5?
Absolutely. Installing a Glock 34 Gen 5 threaded barrel OEM or aftermarket barrel is a direct drop-in swap on most models. It’s a popular upgrade for adding a compensator or suppressor. Just ensure you purchase a barrel specifically labeled for the Gen 5 model due to slight locking block differences.
Is the GLOCK 34 GEN 5 good for beginners?
Its size and weight actually make it a very soft-shooting and controllable pistol, which is excellent for beginners learning recoil management. The long sight radius also helps teach proper sight alignment. The only downside for a new shooter is its large size might be harder to handle for those with very small hands.
What holster fits the GLOCK 34 GEN 5?
You’ll need a holster designed for long-slide Glocks. Holsters made for the G34, G35, or G41 will typically fit. Many holsters for the G17 will *not* fit because the slide is longer. Always check manufacturer specifications to confirm G34 Gen 5 compatibility.

Product is fine but shipping took 6 days instead of the 3 they estimated. Not a huge deal but worth mentioning.

Bought this as part of a larger build project. Californiagunshop had the best price by a decent margin and shipping was fast. The GLOCK 34 GEN 5 itself is well-made — OEM-spec fit. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.
