What Makes the GLOCK 34 GEN 5 a Standout Choice?
You’re looking at a tool, not a toy. The GLOCK 34 has always been the go-to for shooters who need an edge in competition or a reliable, accurate sidearm for duty use. The Gen 5 iteration isn’t a complete overhaul; it’s a series of intelligent refinements. They took a platform that worked and polished the rough edges. The result is a pistol that feels more natural in the hand, cycles smoother, and points more intuitively. If you’ve handled older Gen 34s, the difference is immediately apparent. If you’re new to the long-slide game, this is the model to start with.
Key Features Engineered for Performance
- Extended 5.31-inch Barrel & Slide: The increased Glock 34 Gen 5 barrel length provides a longer sight radius for improved accuracy and allows for higher muzzle velocity. The Glock 34 Gen 5 slide is cut with a large window to reduce reciprocating mass, aiding in faster follow-up shots.
- Gen 5 Upgrades: Features the marksman barrel for enhanced precision, an ambidextrous slide stop lever, and the nDLC finish for superior corrosion resistance. The flared magwell and lack of finger grooves on the frame offer a more universal grip.
- MOS Ready (Optional): While this standard model has a traditional slide cut, the Glock 34 Gen 5 MOS variant is available for those who want a direct optics mounting solution without sending the slide off for milling.
- Enhanced Reliability: The Gen 5 eliminates the half-moon cutout at the front of the grip that some found problematic with magazine insertion, and incorporates an improved trigger mechanism.

How Does the GLOCK 34 GEN 5 Stack Up?
A common question we get is Glock 34 Gen 5 vs Glock 17. The 17 is the quintessential do-everything 9mm. The 34 is a specialist. You buy the 17 for concealment and general use. You buy the 34 because you want every mechanical advantage for hitting targets at distance, whether paper or otherwise. The longer slide and barrel make it less ideal for concealed carry but superior for competition, home defense, or duty use where concealment isn’t a priority.

Honest Pros and Cons
Pros:
- ✅ Outstanding out-of-the-box accuracy due to barrel and sight radius.
- ✅ Gen 5 ergonomics are a significant improvement for most shooters.
- ✅ Proven reliability you can stake your life on.
- ✅ The nDLC finish is remarkably tough and corrosion-resistant.
- ✅ Large aftermarket support for holsters, sights, and triggers.
Cons:
- ❌ Size makes it impractical for concealed carry for most people. (For that, consider a Glock 19 or 43X).
- ❌ Some early Gen 5 models had reported Glock 34 Gen 5 problems with the finish wearing quickly, but this has been largely resolved in current production.
- ❌ Not optics-ready in this standard configuration. You’ll need the MOS version or aftermarket milling.
Who Should Buy the GLOCK 34 GEN 5?
Buy it if: You’re a USPSA or IDPA competitor in Production or Carry Optics divisions (with MOS). You’re a law enforcement officer or security professional looking for a duty pistol with enhanced accuracy. You want the most capable, out-of-the-box accurate GLOCK for home defense or range use, and size is not a constraint.
Skip it if: Your primary need is concealed carry. You’re on an extremely tight budget and just need a basic firearm. You insist on a metal-framed pistol. For those looking for a more compact option, our selection of standard and compact GLOCK models will serve you better.
Frequently Asked Questions
Where can I buy a GLOCK 34 GEN 5 online?
You can purchase the GLOCK 34 GEN 5 right here at Glockswitchstore (glockswitchstore.com). We are an authorized retailer, and all firearms are shipped to your local Federal Firearms License (FFL) holder for a legal transfer.
How do I clean my GLOCK 34 GEN 5?
How to clean a Glock 34 Gen 5 follows the standard GLOCK field-strip procedure. Ensure the pistol is unloaded. Pull the trigger to decock (with empty chamber pointed in a safe direction). Pull down on the two slide lock tabs while pushing the slide forward off the frame. Remove the recoil spring assembly and barrel. Clean all parts with a quality solvent and lubricate lightly on the rail contact points, barrel hood, and connector. Reassemble in reverse order.
How do I disassemble my GLOCK 34 GEN 5?
The process for how to disassemble a Glock 34 Gen 5 for routine cleaning is described above. For further detail stripping (removing pins, trigger assembly, etc.), I recommend using a GLOCK armorers manual or a trusted YouTube guide. The Gen 5 uses a revised trigger housing pin that is not interchangeable with previous generations.
Does the GLOCK 34 GEN 5 have a threaded barrel?
The factory OEM model does not come with a Glock 34 Gen 5 threaded barrel OEM installed. However, aftermarket threaded barrels are widely available from brands like SilencerCo, Faxon, and Bar-Sto if you wish to attach a compensator or suppressor. Ensure you check local and federal regulations regarding threaded pistol barrels.
What is the difference between the Gen 5 and older Gen 34 models?
The Gen 5 features the marksman barrel, ambidextrous slide stop, nDLC finish, no finger grooves, a flared magwell, and the removal of the half-moon cutout on the front strap. Internally, the trigger bar and safety mechanism are updated. These changes improve ergonomics, corrosion resistance, and slightly enhance accuracy.
Is the GLOCK 34 GEN 5 good for competition?
It is one of the most popular pistols in practical shooting sports. Its long sight radius, inherent accuracy, and reliable operation make it a top choice for divisions like USPSA Production and IDPA SSP. The MOS version is ideal for Carry Optics divisions.
What holsters fit the GLOCK 34 GEN 5?
It will fit most holsters made for the GLOCK 34, though Gen 5-specific holsters are best due to the ambidextrous slide stop. Holsters for the GLOCK 17 will often work if they are open-ended, as the 34’s slide extends past the 17’s dust cover. Always verify fit with your specific holster manufacturer.
