The Glock 34 Gen 5 MOS pistol is perfect for competition shooters or for a home defense pistol with easy attachment of any style optic you want.
The barrel is 5.31" with an overall length of 8.74", so it’s going to be very difficult to use as a CCW. The Glock 19, 26, and 43 are all great Glock to use as your everyday carry pistol.
The Glock 34 comes with the Glock Marksman Barrel (GMB) for improved accuracy because of the polygonal rifling and improved barrel crown. It’s built with an ambidextrous slide for use by left and right-handed shooters and has no finger grooves (like all Gen 5 Glocks).
The incredibly long sightline (7.8") on this pistol gives the shooter a better line of sight and the ability to line up the shot quicker and more accurately.

Why Should I Buy The Glock 34 Gen 5 MOS?
They led many gun owners to believe that compact pistols are good for home defense because they’re so practical for your everyday carry. In my experience, this couldn’t be further from the truth.
You want a bigger, longer barrel, a higher capacity pistol for home defense because it gives a better chance at hitting your target under extreme stress. I’ve been fortunate to gain the experience of a fire-fight in my 2nd Iraqi deployment and learned a lot.
For example, the adrenaline rush you’ll feel if your life is in danger is unlike anything you’ll ever feel. This is one reason it’s so important to train with your weapons as often as possible to gain muscle memory. Having a pistol with a longer barrel and larger capacity will give you the best chance to overcome the jitters you’ll get in your hands and put bullets on target quickly.
The Glock 34 is one of the easiest Glocks to customize because it’s one of the largest and most popular competitive shooting pistols. There are so many accessories that it’s hard to list them all, but we have a few that will really make you think. I want to emphasize the RDS optics for the USPSC competitors, extended magazines, and some cool backplates that allow you to show your personality.
Leupold DeltaPoint Pro Reflex Sight
The Leupold DeltaPoint Pro Reflex Red Dot Sight features a scratch-proof lens with the DiamondCoat lens coating that prevents abrasions from drops, falls, trees, fabric, and even other guns or metal. It’s enhanced with the durability to withstand 5,000 shots from the Leupold Punisher recoil simulation machine.
This machine simulates 3x the recoil of a .308 rifle. The entire optic is waterproof, shockproof, and fog proof, so I can use it in any environmental condition without worrying about if it gets wet.
It also uses the patented Twilight max Red Dot Sight System, which ensures that the color and image you see through the optic is always the exact color and image, regardless of the time of day. They make the Leupold DeltaPoint from lightweight aluminum that disperses recoil to add an extra layer of protection. Finally, Motion Sensor Technology (MST) automatically deactivates illumination after 5 minutes of inactivity to extend the battery life.
The Trijicon RMR is the official ACOG sight for the USSOCOM career fields and one of the most popular red dot sights in the world. Whether you prefer the Leupold or the RMR, you can’t go wrong with the reliability, durability, and practicality of the sight. The RMR absorbs the impact of your pistol while diverting the felt-recoil away from the lens to ensure the dot is always centered and accessible.
It features a multi-colored lens to cover as many colors on the spectrum as you’ll encounter from the dazzling sun reflecting off the desert ground or twilight. The windage and elevation knob is easy to understand because each click changes exactly 1 MOA. The RMR has the best possible waterproof features I’ve ever seen with the ability to submerge up to 66ft of water without breaking the seal.
The Vortex Viper is one of my favorite optics to use because it’s comparable to the previous 2 optics, but will save about $200-$300. Obviously, Trijicon and Leupold are incredible companies with an unapproachable reputation, but if you’re looking for a great optic without spending the exuberant amount of cash, it takes to own one. This Vortex Viper is for you.
It features a 6 MOA red dot that is protected by multiple coats of anti-reflecting coating that enhances your sight picture without getting blinded by the glare of the sun. It has unlimited eye relief, which means you don’t have to close 1 eye while you aim.
This, along with the multi-coating on the lens, makes this optic parallax-free without straining your eyes. The most impressive feature of the Viper is the battery, which lasts up to 150 hours at the highest setting and up to 30,000 hours in the lowest setting.
A magazine extension is surprisingly a hot topic, both political and in competitive circles. I’m a firm believer in less is more, regarding weapon attachments, but I’m also a realist. If I can get an extra 15 rounds without reloading to use as my self-defense pistol, I’m going to take that every time. One of my favorite magazine styles for both my AR and pistols is the see-through magazines that allow me to see exactly how many rounds I have in my mag. I know many of you probably think that I should just count my rounds like every other shooter.
Before I get skewered by internet trolls that hide in wait for a mistake, I love the translucent magazines from Elite Tactical Systems to train with on the range. I believe everyone should train with their gear enough to know what a fully loaded Glock 34 feels like versus a Glock 34 with a few bullets left.
Everyone can get to that point, but it takes time and training. The translucent magazines help me train without having to unload my magazine to see how many bullets I have. This understanding in real-time has helped me tremendously to get a great feel for the difference in weight with a fully loaded and half-loaded magazine.
Constructed of black anodized 6061 Aluminum, the Faxon EXOS Pistol Compensator features a uniquely angled front port single chamber design, enabling the compensator to improve shot-to-shot consistency by reducing muzzle climb and recoil.
The angled port design allows gas to deflect upwards as opposed to only deflecting to the sides, reducing the up and down muzzle movement and improving overall reliability.
The Glock OEM 33-round Glock 34 Magazine would be my choice because of the overall capacity. The standard mag for a Glock 34 is 17-rounds, so increasing your capacity by almost 50% is an extraordinary advantage to have. I also really like the high-capacity because who knows how long they’ll be legal to sell and buy online with the ever-changing gun laws we have.
Many people might disagree with me, but I don’t think Glock has a great grip even for the improved Gen 5 models. I understand the desire to get rid of the finger grips of the Gen 4, but those molded grips on Gen 1-4 pistols helped me grip with more control of the pistol.
I think the S&W M&P Shield 2.0 has a much better grip out of the box. With that being said, if you add a Talon grip to your Glock 34, it will instantly make an enormous difference in your comfort, control, and accuracy.
It comes in either rubber or granulated models, but I’d go with the granulated for a tighter grip. For the Gen 5 models, the Talon grip will cover from the trigger to the mag well in any of the backstrap sizes.
There are dozens of companies that make great holsters for Glocks, but there are none with more features and attention to detail than the Safariland 6354 RDS Tactical Holster. I love the Automatic Locking System (ALS) that gives me peace of mind to know as soon as I holster my pistol, it will lock into place with an audible click.
The real reason this holster is so amazing and sought after is the compatibility with optics, such as the Trijicon RMR and Delta Point Pro from Leupold. I use a RAD Pro on my full-size pistols and this Safariland holster works just fine with my Crimson Trace optic as well. I always worry about if the Kydex or Cordura material will scratch optic or light, but Safariland uses a patented suede material to prevent marring of optics and lights, called the “SafariSuede" lining.
Best Tactical Light & Laser Combo For Glock 34 MOS
The Crimson Trace CMR-204 Rail Master Pro Universal Green Laser Sight and Tactical Light is my favorite light and laser combo because of the high-intensity green laser and the 100 lumens bright white light. It gives me a tactical advantage of disorienting my enemy with the light and staying on target with the green laser.
One way Crimson Trace separates itself from the competition is the ability to provide a relatively affordable light & laser combo with unique features. For example, the CMR-204 Rail Master has a built-in activation button, so once you draw your gun, you can activate the laser and/or light with a simple touch of the activation button on either side of the gun (ambidextrous activation).
All CT products come with a 3-year manufacturer warranty and one of my favorite parts about using Crimson Trace is the lifetime of free batteries. I love the idea that I can use the hell out of my green laser and tactical light to train and never have to worry about spending more money to replace the batteries. For competitors that train every day, battery costs can add up quick, but not with the CMR-204 Rail Master.
The Glock 34 and the Glock 17 are very similar guns and often get compared with each other because of their similarities rather than their differences. Starting with the frame of the gun, they’re both exactly the same, so the grip, height, width, and capacity of the guns are the same.
The biggest difference between these 2 pistols is the slide length and overall length, which affects the line of sight. To figure out which pistol you’d like to own, you’ll need to figure out what the purpose of buying the gun is. For example, if you’re a competitive shooter that competes in the 3- Gun competition or you’d like a longer slide for a better line of sight, the Glock 34 is a better option. However, if you’re looking for a CCW, a Glock 17 is going to be the better option because it’s almost 1" shorter overall.
