USA –  -(Ammoland.com)- We have now seen the new Gen 5 Glocks pistols and you might be wondering what the difference is between the GLOCK gen 4 and GLOCK gen 5 handgun models.

At first glance, you may think not a whole lot but that has always been the case with Glock models. Nothing much really changes and what does, is usually very minor. But for those diehard fans, you will notice those Aesthetic changes rather quickly.

Let’s break it down to the nuts and bolts and go over what exactly has changed between these two Glock model gernerations.

According to Glock, there are 35 new or upgrade parts on the Gen 5 model Glock so let’s start with the most obvious being that the finger grooves have been removed. Based on demand, it seems that was one of the bigger requests by the majority. It’s one of those things you either love or hate. I’ve always been a fan of “grip” and finger grooves never bothered me. In-fact, I often times get a good frame stipple done for added texture and grip.

The flared mag-well is another aesthetic change you will notice at first glance. It’s not meant for competition shooting, however it will surely help those who compete ensuring faster reloading or in high stress situations when time is of the essence.

The Gen 5 Glocks ship with Ameriglo GLOCK Spartan Operator night sights up from polymer sights. (Which are still available) This is ideal for low light shooting and accuracy.

One thing most people thought the Gen 5 Glock would have is front serrations. While it looks great, Glock has reverted back on this detail which I think is more ideal for people who like to customize their Glock slides. You will also notice a more rounded front end on the Gen 5 Glock. Furthermore, there is no more locking block pin. Glock will now revert to using a two pin system with all Gen 5 models.

Left handed shooters will be happy to know that the slide stop is now ambidextrous and easily accessible on both sides of the glock Gen 5 models. Sorry to say, that is the only good news I have for left handed shooters for the Gen 5.

I’m a Glock fanboy and have always loved Glock. But at first glance, I had to ask “what makes the G5 a game changer for Glock?” So let’s dive a little deeper.

Above is a view of the Glock 17 Gen 5 next to a Glock 34 Gen 4. The order in the picture is a bit mixed up, but this is how it goes: 17 frame, 34 slide, 17 slide, and 34 frame.

Glock has coated all Gen 5 Glock handguns with a new nDLC finish which is supposed to last longer and protect against the elements better than previous generations. “Tougher and more durable”. That’s good for people who compete and use their Glock outside a lot.

The all new Glock Marksman Barrel! (GMB) apparently has better rifling for improved accuracy. Everyone always wants better accuracy when shooting and this is one of the better improvements I’ve seen so far.

Rolling into a list of internal changes, here are some of the more notable differences.

  • Firing pin has been reshaped to more of a square edge with ramping on both sides.
  • Gen 3 and 4 magazines will still fit the Gen 5 model.
  • The trigger return spring in the Gen 5 has been replaced and moved inside the mechanism housing.

Overall, not a bad list of upgrades. I think GLOCK delivered a good Gen 5 model especially with the GMB barrel. The standard MSRP is a respectable $565 (G19 ~ $559.00 online) which closely compares to most newer Gen 4 models on the market.

Thanks for the article. I am getting ready to buy a G19 and wasn’t sure between the gen 4 or gen 5 so this was helpful. I am not trying to start anything, truly, but the personal attacks on here are over the top. Personal attacks are not okay or as a response to a someone else’s personal attack. It is bullying plain and simple. They are a very unhealthy way of communicating. Try to be respectful even if someone else isn’t. The angriest people tend to be in the most pain. Please don’t bother to reply to me on… Read more »

I own both; my colt 1911 isn’t 1/2 the gun my gen 4 is, and after this article I suspect the gen 5 will make that an even bigger gap. 1911 snobs make me want to sell the gun despite its sentimental value, maybe I’ll give it to my grandpa.

Hello. I am a 71 year old woman who is interested in purchasing a Glock. I had a Glock 17 about 15 years ago for about a year then sold it. I used it for target practice and was moving to be close to my grandchildren and did not want a gun around because of them. Can any of you suggest a Glock that would be good for a 71 year old woman who just wants it for protection? I plan on taking a concealed weapon class and also practicing at a gun range. I know nothing about guns but… Read more »

I keep telling everyone Glock guys are assholes. This just proved me right. Go out and get yourself a 1911 and see what real men shoot.

Re some of the posts seen here, an old saw comes to mind. As has been not d, Gun Owners Are Their Own Worst Enemies. Unfortunately, this seems more and more a truism.

Bought a 19X about two months ago. I’ve put about a thousand rounds through it- mostly Atlanta Ammo fodder. So far, I’ve had one failure to feed but no other problems. The magazine on that issue was very dirty- I was interested to see if it was gonna puke right outta the box. So far, I’m impressed, line up the sights, squeeze the trigger, it barks- just like it was designed to do. Aren’t any mysteries in Glocks. In all honesty- if you stay from the cheaply made guns, and you know who they are, it’s pretty easy to find… Read more »
