12 Instant Upgrades For the Glock 19
The fifth generation Glock 19 is a major step forward, even though the gun looks almost like every other Glock, ever…
A lot of the touches came from the tuning community, the likes of Agency Arms, ZEV Technologies and Taran Tactical Innovations. The high-priced mods these companies made to the Glock 19 Gen 4 and Gen 3 had a massive impact on the design of the Gen 5.
The flared Magwell, groove-free grip and more come direct from the custom Glock world.
You can see the design influences, together with some unique touches, in this list of the best custom Glocks in the world.
But what if you have a Gen 3 or Gen 4 Glock? Well you have the start of a good gun, but man it needs some work.
The stippling, trigger, magwell and quite a few other things just suck. But then you know that…
So what are the best mods you can make to a Glock Gen 4 or Gen 3 right now to make your Glock a lot, lot better?
1. Connector Plate
- Price: $15
This should be the first thing you do. It’s a cheap modification that gives you a lot of return for your money.
It isn’t quite as hardcore as the Glock modifications on offer from ZEV Technologies, but for less than the price of a steak you can sharpen up your Glock’s trigger with this simple aftermarket Glock part.
Seriously, it’s $15. What do you have to lose?
2. Taran Tactical Innovations Baseplate
- Price: $34.00-$50
You might recognize this Glock accessory from John Wick Chapter 2. There, the antihero takes charge of a TTI Glock 34 Combat Master Package, which will cost you more than $2000 in total. The mag extensions, though, are yours for less.
If anything, capacity is underrated when it comes to a handgun. It gives you options and the extra 5 rounds of 9mm that this baseplate bestows upon your Glock 19 means you now get 20+1.
That’s tactical pistol levels of ammunition, for just $35-$50 and you can buy them for your .308 Win rifle and other firearms too now. We like these extensions. They’re well made and they give your firearm a real tactical boost. They are great at the range, too.
I think this is a bargain, so get a few and you’ll see how much of a difference that extra capacity makes.
3. ZEV Technologies Pro Magwell
- Price: $95.00
It’s such a simple concept that literally every custom Glock manufacturer in the known world did it, then Glock finally followed suit with the Gen 5.
It’s a simple mod that will transform the reloading aspect of your gun. Combine them with the John Wick magazine baseplates and you’ve got a different handgun on your hands.
A flared magwell does what it says on the tin and guides the mag into place. With this in place, though, you’ll find you can move much more confidently with the gun and your mag changes get faster.
4. Grip tape decals
- Price: $10-$20
You know the stippling on your Glock is all wrong, and yet you don’t go and spend less than $20 to fix the problem? You can sort this on eBay and there are some great options.
It doesn’t matter what it does to the aesthetics, you need to be able to rely on your grip. I don’t think you can with the Gen 3 or Gen 4 Glock. The finger grooves in the Mark 4 do help, a bit, but it would be better to have a proper grip that helps you get high up on the pistol.
You can spend insane amounts for Wilson Combat or ZEV stippling, or you can take the easy option and invest in one of about 1000 decal grip tape designs. The slab sided nature of the Glock helps you here, it will take more or less any decal, so get creative with your custom Glock 19 grip.
Really a decal grip is just a pre-cut design and you can go for the look or the functionality. I’ll take the functionality…
You can get rubber sleeves, which can fix the finger grooves in the Gen 4 that proved so popular that Glock removed them for the latest gun. They look awful, though, so there is that…
Get a pre-cut grip tape bestseller on eBay and as long as you don’t mess up the install then you should get a pretty solid finish. You will also have a proper grip on your gun, perhaps for the first time.
5. Reflex Sight – Leupold DeltaPoint Pro
- Price $399.99
This is a cost-effective alternative to the RMR Trijicon and it’s a reflex sight that you can switch between your Glock 19, your AR-15 and even your tactical shotgun.
Leupold makes some of the best rifle scopes in the business and the glass is top quality. This is a cheaper option than the class-leading RMR, but it’s hard to see where you’re cutting corners. It’s a solid bit of kit.
The aspherical glass gives you a distortion free, crystal clear view with the red dot lighting the target up like a Christmas tree. It’s motion sensitive, so it lights up when you need it.
A lightweight aluminum housing combines with sprung steel to provide the shock resistance you need. It’s a sight that will serve you for years and you’ll learn to love it.
The Leupold Reflex Sight vs RMR Trijicon is a tough call, but the glass is much clearer on the Leupold and you’re not working in a constant blue-green haze.
That means the Leupold is more flexible in different conditions in the field and user reviews online say it’s much simpler and less taxing on their eyes. I agree, and think this is a more flexible sight that I prefer. The fact that it’s also a cheaper alternative to the RMR Trijicon is an added bonus.
6. New Slide
- Price: $200-$700
Now let’s get one thing straight, I really don’t believe you’re going to feel $500 of felt recoil reduction. I don’t think this simple piece of ventilated metalwork means your gun will suddenly defy the laws of Physics and shoot flatter than a quiet lake.
I do think that a new slide transforms the look of the gun, though, and fixes all the issues you’ve got with manipulating the flat and smooth slide. If you’re going for true functionality then make sure it’s RMR ready. Other than that, it’s your money and your choice.
You can choose from Agency Arms, ZEV Tech, and many more at Brownells in the link at the top. Rainier Arms also has a great selection and you can find them here.
Only you can really decide if it’s worth it.
7. ZEV Tech Threaded, Match Grade Barrel
- Price: $261.99
If you’re going for a ventilated slide then you should have some jewelry peeping through underneath. Alternatively, this is the quickest and cheapest way to get suppressor ready.
This threaded barrel gives you the option of a suppressor and the polished end protrudes from the slide to give you a tacticool look. It’s just a little gunporn to get you through the day.
The barrel itself is machined from stainless steel, polished to perfection and then delivered to your door.
It will make a difference to your grouping and it should give you that nth degree of consistency. That’s what a Glock 19 is all about, but if you take it this far then you’re well into the realms of a custom gun that should be worth more than the considerable sum of its parts.
8. Tritium Night Sights
- Price: $90.00-$190
Self-illuminating Tritium gives you that glow that makes it easy for you to line up your gun in dark conditions.
It might not sound like a big deal, but in a stressed out self-defense situation then that can be a lifesaver.
This is one of the simplest Glock parts and accessories to fit yourself, which is why the night sights are a solid gateway drug that can take you to a dark place of overspending and then rationalising it later.
9 Drop In Trigger
- Price: $70-225
The trigger is often the first custom Glock modification that people make. But really the connector plate on its own will make a big improvement.
You can choose from Agency Arms, ZEV Technologies, CMC Triggers, Agency Arms and even the cheaper line-up from Brownells. They’ll all be an improvement, although the competition spec triggers are eye-wateringly expensive custom Glock parts.
If you have a previous gen Glock 19, you know that the trigger is bad. It’s vague mush and you can do better. Why didn’t Glock? It’s a question only they can answer, and I’m not sure they ever will.
This red drop-in trigger will give your gun a flash of color, as well as a much sharper trigger. It will tighten up the whole gun and it’s a simple, devastatingly effective Glock accessory you can fit.
Yes it’s the best Glock 19 modification you can make. You might want to play with different spring settings to get the most from your new trigger set-up too.
9. Crimson Trace Laser
- Price: $233.31
You might not need a laser, but there are certain times in life when you wish you had one. When something goes bump in the night, it’s nice to know that you don’t really have to aim at all. It’s one less thing to think about and a massive tactical advantage when you’re in a bad place.
So, would I have a laser on my nightstand pistol? Controversially, yes….
It might be a different matter with your EDC, in part due to the fact that you’d have to change your holster to accommodate the Crimson Trace. Is that worth it? No, not on a CCW, but for a home defense handgun this is absolutely a Glock accessory I would invest in. If I liked Glocks, which I don’t….
X marks the spot with a Crimson Trace laser, it’s really that simple. It’s solid, rugged and the user reviews online make this one of the favorite Glock accessories out there.
Get one, never miss again and find out why a laser is an awesome pistol modification.
10 Raven Concealment Systems Eidolon Holster
- Price: $144.99
This is the Kydex holster that government agencies rely on. It’s designed to be modular, suit most users and act as a permanent safety for your Glock 19.
It’s also designed to properly retain your weapon, so you don’t have to think about it when you don’t want it. When you do, this holster releases smoothly because it’s built to a higher standard.
If you’re rocking a cheap holster, then you need to try the very best Kydex options and you’ll never go back. It feels better, it looks better and it works better.
Get one today.
11. Trigger Guard Undercut
- Price: Free, borrow a Dremel
The trigger guard undercut is one of the big visual differences of the custom Glocks and it’s something you can do at home with a borrowed Dremel.
Pro-tip, if you do alot of work to your guns or start doing builds, you’ll need a Dremel of your very own. You could even rework old Glock slides like this if you get good with the tools.
It’s worth doing the undercut anyway and it doesn’t take massive amouns of skill. Just go slow and take care. When you’re done, you can get higher up on your gun and get a better balance when you’re shooting.
Don’t hack mindlessly at your frame, that will cost you in the end. Go slow, mark your cutting point clearly and use a vice to make sure you don’t slip.
Polish the surface down with wet and dry paper and you’ll have just as good a finish as the pros. If you want to get really brave, you can go for the finger grooves and file them down to a flat finish.
If you can find a belt sander, you can also delete the finger grooves on your Glock 19 like this:
12.Savage Honey Badger 9mm Ammunition
- Price: $30.99 for 50 rounds
There isn’t a bullet for all seasons and while a standard hollowpoint is a safe bet most of the time, you can boost the performance of your gun by feeding it very different ammunition.
Hands down the most important part of the whole equation when it comes to a bullet wound is the, well, bullet.
So experiment. Challenge what you think you know at the range. Honeybadger 9mm is meant to be the most effective ripper out there, but it’s crazy expensive and loading bullets with jagged edges feels like some kind of war crime….
Honeybadgers look like shrapnel when you load them into the gun. Get over that and you just boosted your firepower. This 9mm doesn’t rely on expansion to inflict damage. Instead the cross head screwdriver design just punches through whatever is in its way.
It’s an instant upgrade for the Glock 19. You don’t even have to break out the screwdrivers for this one.
