glock 19 gen 4 upgrades

It did not take long for the Glock to cross the Atlantic Ocean to the U.S. and make its way into the hearts and hands of gun enthusiasts. The polymer frame was not unique but was the first marketed in large numbers. Of course, the military and law enforcement’s interest in the Glock did not hurt its sales and following.

The gun industry has its own naming system for its line, and the Glock is no different in that aspect. Historically, if there was an interest in learning the year of the handgun, a serial number search was necessary. The Glock stands out from many models because it keeps the same number but uses ‘Generation’ to note the differences in the models


Glock 19 Gen 3 vs. Gen 4

Gaston Glock was not a gun maker when he started his gun line. What he was, on the other hand, was an innovator who lived by the motto, ‘If it is not broken, do not fix it.’ This worked out exceptionally well for his Glock lines. The Glock 19 is no different. Glock refers to the Glock 19 as the “all-around talent” that is versatile and well suited for a service pistol and as a backup weapon for concealed carry.

Dimensional Measurements

  • Length – Gen 3: 7.36 inches | Gen 4 7.82 inches
  • Slide length – 6.85 inches
  • Overall width – 1.26 inches
  • Slide width – 1 inch
  • Height – 5.04 inches
  • Line of sight – 6.02 inches

Primary Similarities on Glock 19 Gen 3 and Gen 4

  • Trigger pull weight
  • Saftey
  • Grip
  • Reliability
  • Aftermarket parts

These are great. This does not really show precisely what is different between Gen 3 and Gen 4. Never despair. We have that covered. In fact, there are a few things that were upgraded.

Glock 19 Backstraps

The grips are the easiest to notice a difference in the two generations. The Gen 4 has a bit more texture on the back for the webbing of the hand.

The next upgrade came from the Glock competition team. The grips were a bit too much for smaller hands. Glock heard the complaints and sent smaller backstraps for the smaller-handed shooter.

Glock 19 Grip Texture

The grip texture is rougher on the Gen 4 than the Gen 3. This was, again, from the information from the shooters who would roughen their grips for a better feel. Do not mistake thinking the rougher texture will rub your hands raw like it was sandpaper. The grip texture is better and different, and not much else.

Magazine Release Button

This is the most easily recognizable part of the differences between the Gen 3 and Gen 4. the mag release button is larger and ambidextrous for the left-hand shooter. The release reaches back more than on the Gen 3, making magazine changes much faster – perfect for the serious competition shooter.

Glock 19 Magazine

Returning to the southpaw shooter, the Gen 4 magazines have notches on both sides, so the mags will slide out. The Gen 3 mags have the notches only on the right side. The Gen 3 mags will work in a Gen 4 so long as it is set up for the right-hand shooter. Apologies, southpaws.

Glock 19 Gen 3 and Gen 4 Slide and Recoil Spring

Before we discuss this, it is imperative that you practice gun safety. Repeat: DO NOT BE STUPID WITH YOUR GLOCK.

You can look directly down the muzzle and see that the Gen 4 uses a larger spring guide rod.

It should be obvious why we were so adamant before discussing this particular feature.

The Gen 3 spring guide rod will fit a Gen 4 but not vice versa and only with an adapter.

Non-Interchangeable Parts on a Glock 19

  • Slide and Recoil Spring
  • Frame
  • Trigger housing
  • Magazine release button

Glock 19 Interchangeable Parts

  • Trigger bar
  • Connector
  • Ejector
  • Magazine

Suggested Aftermarket Parts for Glock 19

Since there are so many different parts on the Glock 19 Gen 3 and 4, it is best to consider aftermarket parts that are universal to the Glock system. Ghost Inc. has a few such parts. We would recommend one or more of the following:

  • Slide cover plate – Choose from a variety of different looks and designs
  • MOAB – Mother of all Baseplates – These easily change out with current magazine base plates and provide a bit more surface to take hold of during magazine changes.
  • Night sights – The standard Glock factory sights are plastic. Excellent upgrades make a huge difference in the Glock look.
  • Weapon light – A quality weapon light and night sight could be the difference between you seeing another day and being a statistic.

  1. beryvallarino

    Fast in delivery I received this quick. The gun itself is built amazingly well. Polymer feels like a real glock. This glock 19 geb upgrade is modeled after a 45 caliber. So the weight of the bb gun doesnt quite feel like a fully loaded g19 but its close at just about a pound. Sights are good. Very good purchase. Rating 4 stars because it is non blowback, but they are currently producing those in the near future.

  2. Ndidiog buli

    I would pay twice the price easily. It is simply the perfect dry fire practice gun for Glocks. The gun is very very similar to a G19 gen 4 upgrade. The trigger pull is very similar; there’s a little mushiness after it hits the “Glock wall” at the end of the pull. Another trigger difference is the reset is not the same as on Glocks. It’s longer – almost a full return. But overall it’s incredibly similar – a pretty amazing thing. If you dry fire practice with your Glock, you know you have to rack the slide for each trigger pull. Not great practice. With this gun the trigger returns with each shot. That’s worth the small price of admission itself.

    An extension of my arm, sweet piece of metal
    Put it through its paces, love the perfection. Incomparable craftsmanship.

  4. Mickey mantle

    Perfect Gun
    Great, accurate, flawless gun. Put a few hundred random rounds through it and preformed perfectly. Highly recommend if your looking for a middle sized gun. Big enough to feel like a “full size”, good size magazine, very accurate compared to small compact guns, and still concealable in most attire.

  5. Steven texeira

    Great gun, I love my Glock!
    I bought this a few years ago at Academy. Got the last one they had in stock. I really enjoy target shooting with it. I like the way it feels. It’s very comfortable in my hand.

  6. Patricia limb

    This BB glock is so sick! Got one for my bro and i to shoot in the backyard to practice our shots. Looks and feels just like our real glocks. Same gen and everything. Got a nice kick too! Shot like 5 or 6 clips on one co2 it just gets weaker and weaker but it starts off strong.

  7. Abroberts Livon

    Great dependable 1st firearm. This a 1 purchase I don’t regret. The customer service at academy is awesome as well.

  8. Aashish arian

    Glock 19 Gen 5
    Went to range yesterday and shot 150 times. Not one jam or misfire.

  9. Allana Lorene

    The BB Gun looks and feels like a real gun. Easy to load, holds 18 balls, CO2 cartridge goes in the handle. There is a little Allen wrench that it comes with that you use to open the handle, place the CO2 cartridge, then tighten down. When you hear air leak, you tighten a little more until it stops. This means you have spiked the CO2 cartridge and you are ready to go. There is a safety on the bottom of the gun. When I first fired the gun, i was shocked by the loud pop it gives off. It surprised me. I never heard that with my pump air rifle. But I guess the cartridge has more pressure behind it. As far as accuracy, I didn’t actually use a target. It seemed to be fairly accurate from what I can tell. But I scored it 4 stars just because of my inability to be accurate about its accuracy. 😜

    Been tryna fine a good strap dealer for while I guess I got a reliable plug Atm Oder the 19 g 4 upgrade and it can through

  11. Joey roach

    bought the Gen 4 Glock 19 and I was excited to have this because I’ve had other Umarex products and so far they are all EXCELLENT, but this one is an unfortunate exception, when I opened the package I instantly noticed that the barrel was loose and rattled when I shook it. When it came to loading it, the flaws really started to show. The magazine needs to be loaded from the top where it is also shot out and lacks a locking function which leads to the issue of them slipping out into the barrel before being fired, and I noticed that almost every other bb was either inaccurate or never even came out. After about five or so full magazines the barrel stopped clocking back after the magazine emptied and that was the final nail in the coffin.

  12. Micheal trem

    This gun is really powerful. It’s says around 350fps. 700 FPS can break a collar bone. I shot off 2 clips at a target with cardboard behind it and a wooden fence 25 to 30 feet away. All shots hit a 10×10” target-went right through and lodged into the wooden fence. Had to pluck them out with a knife. Also my friend has a real Glock and was thoroughly convinced that It was the real deal by the photos. Heavy gun. Feels good. Blowback is nice. Pop off 16 shots in seconds.

  14. Desmond Aron

    Lit This bb gun is badass. The gun feels almost like real firearm and is designed to replicate a Glock 19 gen 4 upgrade. The slide is metal and does not move and the rest of the gun is made of quality, hard, durable plastic. I recommend this to everyone, well worth the money.

  15. Kyleh glimore

    This is an awesome pistol, very accurate replica. Feels awesome in hand, however I had a couple of problems. First is accuracy, it is very bad at shooting things accurately at 10 yards. BUT since it shoots bbs, I can’t really blame it on the pistol. However the main issue that I have and you can see on the photo is that the end of the spring metal catch is already deforming and bending the frame. I’m always very careful when releasing the spring and always do it with a full mag (18 bbs), but for some reason it is bending the frame of the magazine and the metal catch at the end of the spring is bent and missing material. I’ve put about 15-20 mags through it and like I said, always careful with the spring release. I guess it’s either my mag that has a problem or I’m doing something wrong. All my other umarex pistols are great and I have never had this problem before.

  16. E Johnson

    Hands down the best 9mm out there. I’m a bigger guy and this gun has close to no kick back like the 40cal or smiths 9mm do. Definitely a must have for everyday carry. Never disappoints or jams ever.

  17. Amanda

    I bought this gun 4/20/22, I am so happy get this. this gun trigger too tight. I have small hand, this grip is too wide, but grip is too short. Maybe G19 grip is better and comfortable.

  18. smartman

    Best G dealer I ever came across can believe shit was here so quick amazing packaging 📦 bet

  19. David Fritz

    This is my first hammerless gun. But the Glock 19 has great balance and the recoil is much less than my Ruger P95.And the great thing is it can take all sorts of rough situations and still I can depend on it. Thank you Glock you made me a believer in Hammerless Guns

  20. Adam Carter

    has nice weight to it. Definitely feels like you’re holding a Glock. Functionally I have no gripe, it does exactly what it says it does. Craftsmanship is lower quality than I expected. The slide is loose horizontally it will rattle if you move it quickly. Accuracy is about what you’d expect from any decent .199 and it fits any Glock 19 holster. Good for practice. I just wish the side was a little more tight. Probably the Gen4 is well worth the extra $40.

  21. Limossey mason

    Awesome Handgun for Everyday Carry
    I love my Glock 19 Gen 5. I’ve put about 300 rounds through it so far and it’s worked great each time. I like that it has a 15 round magazine but is still small enough for concealed carry. Overall, it’s a great gun and I’m very happy with my purchase.

  22. Sandra trimi

    All in all this is a great replica air gun. I like the blowback feature and the accuracy is good. It runs through CO2 pretty fast and the trigger feel is not great. It feels like a real Glock 19 in your hand. I think, although I haven’t confirmed that the states muzzle velocity numbers are understated. It seems a lot more powerful than my John Wain replica colt, my umarex replica Sig and of course my Daisy Red Ryder. I’d give it five stars if it weren’t for the trigger. Otherwise it’s a great buy. If you don’t care about the blowback feature you could get as nice of an air gun for a lot less by buying the Umarex Sig replica.

  23. anderson

    I Rec’d the G19 upgrade today and opened the package finding that I was pleased with the quality and the look on it. Loaded the Glock and shot around 60 bb’s on one 12g cylinder. Very pleased of the Glock Gen 3 G19 gen 4 upgrade pistol. I would recommend it……..

  24. rakkar

    am a woman This is for a sort of protection thing as we live close to woods. So when the zombies come I am ready!! Hahahaha!!! So I tested it out in the woods behind me so the EASE to use is ridiculously easy! Accuracy really decent for somebody who is not experienced with a BB gun at all. Has a really good weight and feels good in the hand not too much for a girl The handle but I am in no way shape or form saying this is a girls gun.I am the type of girl who thinks that guys things are just made better in certain categories… I am a girly girl but I buy men’s razors, men’s deodorant… Usually men’s sneakers… Sometimes things like even men’s sweatshirts. They are made better and usually more cost-effective we are in one of those situations here I .think it’s a great value.I just read a ton of reviews and made my choice and got absolutely nothing for writing this awesome review.
