Glock 34 9mm


Not much has changed on the Glock 34, and it is still the most popular choice for Practical Shooting competitors, including Dave Sevigny, the most prolific winner in the history of the USPSA Production division.

The G34 featured a 5.3-inch barrel on a full-size frame that housed a 17-round magazine. The G34 has a large cutout in the top of its slide. It might just be the easiest way to produce a slide of the proper weight so that reciprocation remains smooth and reliable.

The G34 configuration (shared by the 40-caliber G35) is the only Glock sold with adjustable sights as standard equipment. It was also the first Glock sold with competition-bred options such as an extended magazine release, enhanced slide-release lever, and a 3.5-pound connector that reduced the weight of the trigger pull. The fact that Glock has a head start when it comes to innovations from the world of Practical Shooting should not be underestimated.

This is Glock's action target pistol. Consistent shot-to-shot performance was its strong suit.

In our assessment of the XDM we mentioned that the XD’s trigger required take-up to a definitive point of resistance. The Glock on the other hand offers a feeling of continuous compression. Indeed, that is exactly what is happening. The spring that powers the striker of the XD is almost completely loaded by movement of the slide. The trigger of the Glock does much more of the actual compression. Over the course of this compression we think the Glock shooter is dialed into the process. Results from our accuracy tests showed an average size group of about 2.5 inches across firing full-metal-jacket rounds. This was about the same performance as our Springfield Armory pistol. But when firing the 124-grain Speer Gold Dot ammunition, the G34 was a close second to the CZ.

The adjustable rear sight on our G34 featured a white outline that was bolder than on previous models. It is the only Glock pistol with adjustable sights as standard equipment.

The first target of our action test showed a 7-inch-wide group almost perfectly centered on the target. The central target furthest from the shooter did not look much different than the left-side target which was engaged first. The group did not show any hits on the 3-inch bulseye, instead forming a circle around it. The target to the right was engaged last.

The remarkable aspect of the hits on this target was that it displayed four pairs of snake-eyed hits with the holes less than 1 inch apart. We read this as showing where the shooter stopped on the target to fire his two shots. Consistency from shot to shot was perhaps the greatest attribute of the Glock 34.

I think you all have valid points. I own a Glock and love it, but it has always bothered me that ANYONE can pick up a Glock and fire it. Therefore, I don't keep one in the pipe and I NEVER put my finger on the trigger until I'm ready to shoot...but that's me with my gun. After all, how long does it take to rack a slide...1 second? Secondly, there are now aftermarket triggers that fix the no secondary safety problem. Go take a look at the Lone Wolf Siderlock. I saw one installed on a gun at a show and I like's simple and effective. Keeps the trigger safety from being disengaged.

Feel free to rant about that too.

Mr. Smith; You are right! I have gone through two courses our conceal/carry classes to obtain & renew my carry permit. YOU DO NOT PUT YOUR FINGER ON THE TRIGGER UNTIL YOU ARE READY TO SHOOT. My instructor would then repeat; "anyone worth shooting once is worth shooting twice"!

Wild Romanian you are an idiot. The Glock is used by far more police officers in America than any other hand gun and there is a good reason for this. The first thing your taught in basic firearm safety is "do do not put your finger on the trigger unless your are ready to fire". If a person lacks the training or even worse the ability, to unconsciously NOT PUT THEIR FINGER ON THE TRIGGER until on target and ready to fire, SHOULD NOT HANDLE A FIREARM PERIOD!!!! Your example of a cop throwing a loaded gun onto his bed with a child in the room is ridiculous. The safety mechanism of the gun is not the issue in that scenario. Grow a brain Romanian.

Quotes:It is unacceptable that a person who has received a "training real professional, made by professional instructors, commits the lightness of leaving a gun on the bed knowing you have a child at home. This is regardless of whether a Glock, a 1911 or a WONDERNINE. A person who commits an act like this is a irresponsabileed a fool, that never ever should have been granted to carry firearms. People like this should change jobs and go digging!

It doesn't matter if the gun you carry has a safety or not and it doesn't matter how tired you are at the end of any day. Your gun is YOUR responsibility and it is not legal to allow a child access to your weapon. Quotes:

You are all over looking the facts. It happened and continues to happen. Singing the Glock philosophy songs do not bring back the dead or prevent needless future deaths. People are human beings, they make mistakes, we all make mistakes sooner or later. Safer designs in firearms are nothing new, they were being made way back in 1911. This nothing new or earth shattering even to conservatives or at least it shouldn't be. Why would a modern firearm be made less safe than one made in 1911. Its a no brainier assuming one has any grey matter between his ears to begin with.

Quote:Dear Wild Romanian: GLOCK's manual says it all... "If you don't want to fire the gun, don't touch the trigger." jamraqui Quote.

I am afraid you have fallen hook line and sinker for Glock propaganda, either that or you are naive enough to believe that an accident can never happen to you personally.

The real facts are that people are human. They are affected by fatigue, stress, lack of sleep, to much alcohol or drugs etc. etc. With a Glock in hand they are far more likely to shoot themselves or someone else unintentionally.

Now lets look at some real life Glock tragedies. Place: Chicago. Person: A police officer comes home very tired and stressed out. He undresses and throws his Glock "unsafe action" down on the bed. His small daughter snatches up the gun right in front of him. She touches the trigger and blows her head off. This would have never happened with a more safely designed pistol, even one designed way back in 1911. The little girl would have never been able to shoot herself so quickly with this design. Even if the gun was cocked she would have had to push off the safety and then deactivate the grip safety while pulling the trigger, something she could not have done with her very small hand reach. This is only one of many tragic accidents I have read about in the news all the result of the totally unsafe Glock design.

@Wild Romanian,
Anyone who stuffs a "ready-to-go" pistol into his waistband without a holster to protect the trigger from actuation is practicing unsafe gun handling. Such people should probably not drive cars, either.

Others can do whatever they want, but holstering any pistol with a loaded chamber is a task I perform with great care and concentration. Those who are cavalier about it should not be shocked if they shoot themselves, and this is NOT a function of the gun, it is a function of violating the "No Bozo Zone" that surrounds the gun.

The GLOCK first and second series, in caliber 40 S & W had the room is too large, and so there was some KABOOMS. The problem has been resolved in the third set with the reduction of the room.
SAFETY shooting of the first second and third series was 2200gr. that of the fourth series was brought to 2500gr.
An accidental explosion can not happen with the Glock.
p.s. can only occur with an idiot.

wild romanian - Glocks do not accidentally fire. The only way to make a Glock fire is to pull the trigger. Keep your finger off the trigger it will not fire. Guns are made to fire when the trigger is pulled. That said I would never carry my Glocks without a holster to cover the trigger guard.

Gaston Glock has done for the handgun what Gene Stoner did for the infantry "assault rifle". The good news is that Mr. Glock did not rush his gun to market before perfecting the safety, reliability, and accuracy of his product. Yet, the Glock is not for everyone. It is only for those that have better safety habits than the typical cop of 20+ years ago. Yes. It is no secret that, not so long ago, cops were some of the worst safety offenders in the USA. My NRA instructor friends, to this day, retreat to a safe location whenever "highly trained law enforcement or security professionals" show up at the range. So when you hear that accidental discharges happen "including police officers" with the Glock or any other gun don't be surprised. All of my Fire Armes instructor friends would rather teach novice housewives than deal with "know it all" cops. For those that demand an external safety: Get a Springfield XD, or any one of a dozen Glock copycats available. I suspect that most of the stories attacking the safety of the Glock are not true.

A few Glock haters here...

Caption to above photo is incorrect; Glock 17L and G24 ALWAYS come with adjustable sites. G34 and G35 come with standard adjustable sites on civilian models (and 4.5# connector) and fixed sites (and 5.5# connector) on LE pistols. Glock adjustables are *functional*, at best and are usually replaced by serious competition shooters.

On Glock's .40 cal, they have increased the chamber support over the years and that is no longer considered an issue.

Glock as a DAO is safe in the hands of a any competent shooter - LE, Military or civilian. Thousands have been carrying Glocks safely for decades now, with a round chambered, as both duty weapons and concealed carry.

Glocks are not for everyone... they are NOT 1911s or Sigs or Berettas - but they are a sound and proven weapon system.

Dear Wild Romanian:
GLOCK's manual says it all...
"If you don't want to fire the gun, don't touch the trigger." Even if they DID go off "with a light touch of the trigger" (which is an out of hand statement in itself), not touching it at all (hence, the manuals instructions) makes obvious sense. It's time for people to assume responsibility for their own mis-handling of products of all kinds, including this one. It's too often an American perspective to blame an inanimate object for it's user's inattentiveness. People that shot themselves with their own GLOCK were mis-handling them... it won't fire any other way than handling it. The gun did what it was told to do by it's owner's hand... it did not fire of it's own volition. Period. Let's all man-up and stop blaming pieces of metal for our inadequacies or accidents.

Rant done. :-)

More than any other pistol the Glock has had the most accidental firings that have resulted in many unnecessary deaths and injuries including police officers, one of which was on the national news. The problem is two fold. 1. People do not realize that the Glock has no manual safety and a light touch of the trigger will fire it. Although none of these people would ever consider cocking a revolver and then stick it in their waist band because they can see the danger with the hammer cocked back and no safety, they go ahead and do the exact same thing with a Glock because it does not have a hammer and they cannot see the danger. Result: they shoot themselves. A manual safety on this gun is long over due because even the police have shot themselves and often innocent people because of the Glocks lack of a manual safety. The Glock trigger is actually a single action trigger not a hard to pull long stroke trigger that is found on many other double action pistols. This is why it needs a manual safety and a grip safety too would not be a bad idea either. I am told Australia will not even let any Glock into their country without the addition of a manual safety which Glock does supply but unfortunately not to the American market.

Glock does have a heavier "New York" trigger that the NYPD demanded because of too many accidental shootings but it was not a panacea because of the Glocks single action trigger system. In other words the gun still needs a manual safety.

Anybody know if I can order this online and have it sent to my local dealer for pickup? Can't seem to find one in my neck of the woods. Mendocino County, California

I have a stock G34 that will shoot delightful groups at 50 yards from a rest. More accurate than my Browning HP.

I hate to burst wild romanian's anti-40 bubble, but there are hundreds of Law Enforcement Agencies using 40 S&W as their standard issue weapons. They don't seem to be suffering significant "kabooms".

Posted by: digitalexplr | November 26, 2009 10:45 AM    Report this comment

I have fired and seen others fire over 50,000 rounds of 40 S&W from various Glock models, and Sig and H&K as well (vast majority were Glocks). All with full load duty ammo and have NEVER seen a Kaboom as they like to call them, nor have I seen a slide and barrel leave the frame when correctly assembled, (never seen it period but if mis-assembled I will give it a remote chance if it functioned at all)

Yes there was and is a recall on the Glock passive safety system and also its extractor. It is called an "update" as if we were to stupid to know its a recall.

One other note on the 40 S&W caliber. Several years ago Combat Handguns Magazine reported that several modern made handguns a Glock, a Browning High Power and a Ruger, all blew up in the 40 S&W caliber using factory ammo. There have been quite a few internet posts showing horrific blow ups with other 40 S&W Glock pistols. Conjecture is that the generous throating of the Glock coupled with its ability to fire out of batter coupled with the 40 S&W cartridges tendency to blow up when it suffers bullet set back makes his a caliber to stay away from period. Never ever stand next to a person firing this caliber when on the target range.

Hey SILVER DOLLAR; Are you saying there is a recall on this Glock? I am considering buying this model. My wife & I want to shoot in local comps and this looked like a good gun to me. I have a model 19 & 17 that I am happy with, the adjustable sights are a plus on this G34.....THANKS.

Can you trust a company that will not contact you on a recall? A recall were the slide could come off the frame. This makes your firearm potentially more dangerous to the user, than the bad guy!

I've put 10's of thousands of rounds through my G34 and never have had a malfunction of any kind. It was my first pistol and still my favorite. I did go with Trijicon sights though, I prefer the three dot to the stock. I can remove the "10" area at 20 feet with 2 mags of Win FMJ target rounds. (I've got the targets hanging on my wall)

I have a Glock 34, had Irv Stone at Barsto Barrels drop in one of his barrels for even more accuracy, it is one very accurate handgun with great firepower, extended slide and mag release, great light trigger, and long sight radius. It shoots as accurate as my Mauser Luger, Walther P88, HKP7M8 and Sig P210 for a lot less money.

Both the 34 and 35(40 S&W) are great comptetion guns, my wife and I have tens of thousands of rounds through them without malfunctions. A bonus of the 35 is the ability to drop in a 357 sig barrel, which gives fine accuracy and over 1450 fps from the long barrel.
Two things to consider; very light 9mm loads (around 125 power factor)invite limp-wristing from the oddball single-handed positions you find in IDPA. Also, the plastic front site can be knocked off when shooting under/through tables and barrels: I Loctite a steel fiber optic sight using a special nutdriver, the sight is still there even if the fiber optic rod gets broken.
