Glock 17 vs 34 – 7 Primary Differences That Matter

Glock 34 vs 17 - Handgun Showdown
When it comes to big and striker-fired 9mm pistols, our top choices boil down between the Glock 17 vs Glock 34 since they’re much alike. Both pistols are popular with law enforcement officers and many gun enthusiasts because of their reliability and overall flexibility. But aside from the 0.8 inches barrel length difference, they also have distinct intended uses. Do these differences really matter?
The difference between the two Glocks is their design as either one works excellent as a home defense gun. However, G34 features a long barrel at 5.31 inches, making it suitable for open carry and shooting competition. Consequently, you’ll notice an approximately 7.5 inches extended sight radius. Yet, the smaller size of the 8.03×1.26×5.47 inches G17 might work best for you if you’re looking for a full-sized pistol for concealed carry. Besides, some also buy a G17 to use when competing.

Design & Ergonomics

In essence, the Glocks have the same frame but with different slides and barrels. G17 has a shorter slide of 7.32 inches compared to the 8.15 inches of the other gun. The G17 has a shorter length as well.

Based on our research, many users used to complain about the uncomfortable carry handle of the earlier versions of the G17. Now, the Gen4 models come with adjustable backstraps for good ergonomics.

Ammunition - Glock 17 vs 34

As reflected on the specs chart, you can get a standard magazine capacity of 17 rounds with extended mags of up to 33 on both guns. Like several other guns, Glock only recommends jacketed ammo for both.

On the G17, we found that the best ammo has velocities between 975fps to 135fps across various bullet weights. Yet, G34 could get you a little extra speed vs Glock 17, which would allow better expansion and penetration.

Trigger

The two guns are striker-fired, which would give you the same consistent pull, with a trigger distance of 2.83 inches. Even so, G17’s 6.29lb trigger pull is a bit heavier than that of the 5.4lb pull of the other.

For us, a lighter trigger pull is greater, so we could focus more on aiming without thinking if it shoots. Nonetheless, we noticed that both triggers are gritty, although both only need a higher round count to make it softer.

Glock 17 & Glock 34 Safety

All Glock guns include its signature Safe Action System built into its trigger. It contains three automatic and independently-operating safeties: trigger safety, firing pin safety, and drop safety. But other than this, Glock designed the handguns without any external safety features. Overall, it’s a draw for both guns in terms of safety.

Sights

G17 comes with a white dot front sight and a U-notch fixed rear sight. Whereas, the competition handgun has an adjustable rear sight and offers a longer sight radius, giving it an advantage on accuracy.

Likewise, if you’re a Glock fan, you’ll know that their standard plastic sights are probably among the most common things that handgun owners don’t like. Still, you can get away with this one through the aftermarket sights.

Glock 34 & 17 Accuracy

Being an accurate pistol is one thing but maintaining that accuracy in rapid firing is a different one. Given this, both guns didn’t disappoint during the time when we shot them. We can easily shoot at 15 and 25 yards. However, if we need to choose, the design and features of the 34 make it a little more advantageous in terms of accuracy.

Glock 17 or Glock 34? We Choose…

Between the Glock 17 or 34, we choose Glock 34. Glock built them with the same frame, technology, and internal safeties. However, its barrel’s size and slide, radius sight, and additional velocity offer various advantages, especially in competitions.

Those who own this gun boast about the expansion and penetrating power of its ammunition as well as the fast and accurate target acquisition.

Yet, if you only want to get defense pistols that might best fit your budget, there’s nothing much that a G17 can’t do.
