Glock G34 9mm

According to the manufacturer, the Glock pistol was the first “industrially manufactured handgun with high-tech polymer grips.” The barrels and slides are coated with what Glock describes as a “high-tech surface refinement” that they call Tenifer. The benefits of this “carbonitriding” coating are not only corrosion resistance and reduced glare but also resistance to abrasion. Tenifer coating is highly rated on the Rockwell Cone hardness scale at 64 HRC.

Some Glock pistols are available with different color frames, but our G34 was basic black. The defining feature of the G34 was its long 5.3-inch barrel with polygonal rifling, covered by a slide that included a gaping hole just to the rear of the front sight. This relief measured approximately 1.75 inches long by 0.75 inches wide. Glock says that this serves to reduce stress on the frame. The dustcover beneath the slide was also longer, making room for a healthy sized accessory rail, which was molded into place. The schematic breakdown of the Glock pistol with magazine lists only 34 separate parts, 36 if you count the magazine insert at the base plate (part 32a), and the front sight blade, part number 16a.

The G34 fits perfectly into the Practical Shooting scene. The long barrel maximizes the power of 9mm ammunition, and the other components deliver precision.

Beyond its overall length and long 7.6 inches of sight radius, what made the G34 special were optional “hop-up” parts. Both the magazine release and slide release were larger for faster operation. We found the increased size of the magazine release to be very helpful, without creating the danger of dropping the magazine unintentionally. But we thought that the slide release could have been larger still or simply checkered to assist operation.

The rear sight unit was adjustable for windage and elevation but still managed to maintain a low profile, making it less vulnerable to damage by snagging, impact, or even a tight-fitting retention strap. Adjustment was by two screws. A tiny screwdriver that proved too easy to misplace was included. Other supplied parts that we didn’t lose were a cleaning rod, a bore brush, owner’s manual, two fired cases, a magazine loader and a cable lock. The two supplied magazines held 16 rounds each.

The adjustable rear sight was as clear and crisp. The two small screws (arrows) controlled windage and elevation.

Our G34 came with a factory-tuned trigger. Actually, producing a light trigger on the Glock system does not necessarily require elaborate parts or machining. The design of the connector is the primary point of control, and all G34 pistols are fit with a 3.5-pound connector as standard equipment. The result was a measured trigger-pull weight of about 6 pounds. At the range we did not find the trigger to be dangerously sensitive, but it did help us land impressive groups from the very first shot.

Without any warm-up or practice, our first group firing budget ammunition measured less than 2 inches across. After a few groups, we had to remark that the G34 was one of the easiest pistols to shoot accurately, even at 25 yards. The longer sight radius helped us focus on the front sight and steer it into place as each shot broke. The G34 offered smoothly modulated recoil, making it easy for the shooter to follow through on each shot.

Our best groups with both the Glock and the Springfield Armory pistol were achieved with the Remington 115-grain JHP rounds. We landed more than one five-shot group that measured less than 1.5 inches across with the G34, for a final average of only 1.6 inches. The Speer GDHP rounds were in second place, but they produced the most power in both of our test guns. The Speer ammunition registered muzzle energy in excess of 400 foot-pounds, proving that longer-barreled guns maximize the power of a given round. We found that the Winchester ammunition performed the same in both guns, producing an average group measuring 2.3 inches for a virtual tie. Perhaps it was merely an indication of a happy range session with many rounds well spent, but even with the 6-pound trigger we managed to wear out our trigger fingers.

The G34 included an extended magazine release and extended slide release (arrows).

The Glock trigger was easy to manipulate, but it asks the shooter to work different muscles than a single-action pistol or even a revolver. The trigger press felt somewhat isometric, but unlike a number of striker-fired pistols we’ve tested, the shooter never had the feeling of an endless struggle devoid of feedback. Overall, the G34 was a well-balanced package expertly tuned for 9mm ammunition.

I have nine Glocks and five Sigs. All are 100% reliable and accurate since purchased. When I carry, it is always a Glock.

Pistols are not made to pick the teeth of a gnat at any number of yards.That is why we have rifles and hand grenades.

A comment on HK squeeze cocker pistols:

When this gun first came out many moons ago I thought that it was "THE ANSWER", until I actually used one that is. It's cocker is on the front strap which can activate when holstering the pistol which can cause an accidental discharge. Many police officers have also had accidental discharges when drawing the gun. Just like the Glock their fingers get on to the trigger too soon and the gun goes off before they are ready to fire.

HK Squeeze cockers have also suffered from broken firing pins.

Powder burning rate is also very critical in this gas operated design. Use the wrong powder and you can 1. beat the gun to death, 2. cause malfunctions, and 3. in rare cases cause a case separation as the action can open to fast.

This gun also overheats itself very quickly which can lead to very early barrel burn out.

Trigger pulls are very, very, mushy. I never new exactly when mine would fire even when shooting off of sand bags.

I vote thumbs down on the latest version of the Glocks for several reasons.

1. Trigger pulls have been made worse not better and parts will not interchange with the new triggers. In the past the 3.5 lb. connector would enable you to get about a 4 lb. pull now its a 6 pound pull. Glock triggers have always been very creepy even with the 3.5 connector installed.

Extended magazine releases are "ABOSLUTELY VEROBTEN" for a carry gun as every brand I have ever tried will result sooner or later in accidentally losing your magazine at the most inopportune time. Try defending yourself with a single shot weapon some time.

The junk plastic sights on Glocks should be trashed immediately and steel sights should be installed. The junk plastic sights not only break off but also wear down with too many holster presentations.

Lastly I have never achieved very good accuracy out of any caliber Glock I have ever fired.

Robert, The HKP7M8 squeeze cock pistol with the fixed barrel is one of the most accurate guns around, only problem with mine is even with the trigger guard heat shield it heats up hot after four or five magazines. The HKP9S is just as accurate has a trigger that breaks like glass and also has a fixed barrel. New unfired models cost a fortune if you can find them, sometimes you can get a good deal on a used one. We are both lucky to have one!

Glocks are great for the cost of my SigP210 a great gun, I could have four or five Glocks!

Pointman, my HKP7M8 is the best shooter I have. Love that pistol!

I carry my Glock 34 in my own design and manufactured cargo pocket holster. It was accurate right out of the box, but I had Irv Stone with Barsto Barrels drop in a 9mm barrel and now it shoots as accurate as my Sig P210, Walther P88, HKP7M8 and P9S AND MY 1911'S.

The 34 in it's stock trim seems to be IDEAL for competition. I compete against them, shooting my (somewhat modified)9mm XD tactical 5" in USPSA production division. The 34 seems quicker, probably `cause the slide and overall weight is less than the XD's.

I have a G35 which is the same gun in .40 caliber. I love the gun and it is accurate enough. I will admit that my Kimber 1911 outshoot everything else in the accuracy dept but I consider Glocks to be excellent fighting guns. I do find that women seem to limp wrist the plastic guns and can make them jam, I cannot even when I try. If I had to defend myself a Glock would be my first choice overall since they are accurate enough, high capasity, and very reliable. I have 4 Glocks and they all work very well for their designed task - self defense.

I hope Mister E is wrong because I've installed a $39,000 Tamko polymer roof on my house. I thought if it was good enough for Glock... Glocks are accurate enough - Glock shooters are not, and it is the trigger. I have the 34 and the 17L and don't shoot either as well as my 1911's.

I read an article in 'Smithsonian' about how much trouble museums are having preserving plastic items. Seems that some plastic items from the '30s and '40s are spontaneously deteriorating as the plastic is no longer stable. I wonder what is the shelf-life of a polymer-framed gun. I pity the collectors in the far future.

i have a friend who has one of these and he claims its' inaccurate. i have not witnessed him firing it, i have seen him shoot other handguns and he is accurate. Wonder if he got a fluke?

The preferred carry for guns of this size is a shoulder holster, especially if you have a wide chest, so that it sits partially hidden. Otherwise, a cross draw holster canted towards your gun hand helps offset the extra length

what's the preferred carry solution for a Glock of this size?
