4 Best Glocks [Across Calibers & Sizes]

“Just get a Glock.”

Glock is one of the most successful and debated about brands in the firearms world.

Group of glocks
A few of the author’s Glocks.

Even outside the gun world, if you know any firearm brand – it’s probably Glock.

Within the gun world, it seems like people either utterly love them or despise them.

There is no middle ground.

However, Glocks do fulfill a niche – an enormous niche – and are here to stay.

And guess what, not all the models are the same.

We’re going through the best and most popular models across different sizes and calibers.

Best Glock Models

1. Glock 17 & 19, Gen 5

It wouldn’t be a “best of” Glock piece without the G17 and G19.

Glock 17 and 19
Glock 17 (fullsize) and 19 (compact), Gen 3

These are, of course, the company’s uber-popular, best-selling full-size and compact 9mms, respectively.

And before we move on…the number 17 and 19 are Glock’s 17th and 19th patents. Nothing to do with caliber or size…

As you now know the G17 was “The Gun That Started It All” while the G19 was the gun that came into being because LEOs wanted a smaller model.

Size Details

The Gen 5 G17 is 8.03 inches long, 5.47 high, and 1.0 inches wide. It weighs 24.87 ounces empty and 32.28 ounces with a loaded mag.

It’s the standard-issue gun for a ridiculous number of law enforcement agencies which has translated to love outside the LE world, too.

Of course, it is a solid, reliable, accurate pistol so it’s all good.

As for the Gen 5 G19, it’s a little smaller.

The G19 has an overall length of 7.28 inches, a height of 5.04 inches, and is 1.0 inches wide. Empty weight is 23.63 ounces and loaded weight is 30.16 ounces. As you can see, their size difference is not significant.

Glock G19 and Target
Glock 19 is a very accurate pistol for its size!


One of the big reasons these models are so freaking popular is that they’re chambered in 9mm. Ballistics have advanced over the years, making 9mm king again after it spent years beaten out by .40 S&W. Is .40 S&W still a hair better ballistically? Yes. Is 9mm a capable, fantastic cartridge?

Yes again.

9mmx19 Parabellum/Luger – yes, both those designations refer to the same cartridge – was designed back in 1902 by Georg Luger for the Luger semi-auto. Today it’s the most commonly-used cartridge in the gun world so you could say Georg nailed it. 

If you’re looking for a classic poly carry gun, you’ve found it.


Both can be concealed – yes, you can conceal a double-stack, full-size gun – but of course the G19 is the model meant for concealed carry.

I have several of these guns and have no complaints whatsoever.

They’re durable, fit my hands well, and accurate. Also, the G17 has a capacity of 17 +1 and the G19 has a capacity of 15 +1.

2. G48

The G48 is a newcomer to the Glock line but it’s gathered a serious fan base right off, including me. This one is also chambered in 9mm but unlike the G17 and G19 it is not a double-stack.

Some would argue it isn’t exactly a single-stack, either; technically Glock refers to this as their Slimline pistol.

The G48 is highly concealable and I’ve found I actually like carrying it in the Crossbreed SuperTuck sometimes rather than sticking to AIWB.

It was released with the G43X, a gun with identical dimensions except for the fact the barrel of the G43X is just shy of one inch shorter. (The G48’s barrel is 4.17 inches long; the G43X’s barrel is 3.41 inches long.)

Glock G43X

Glock created the G48 as the ultimate EDC. At first, I was skeptical – I’m neither a huge fan of 9mm nor a lover of single-stack poly pistols – but I decided to try out the G48.

Long story short the gun proved itself wicked precise, a perfect fit for my hands, and comfortable to conceal. It is my current preferred carry gun.

G48 and mag
The G48 is a freaking awesome pistol. Fight me.


The G48 is a compact gun with a ten-round capacity. Aesthetically it’s noticeably different than the classic Glocks thanks to the Slimline frame and silver nPVD slide.

It has a reversible magazine release, built-in beavertail, and front and rear slide serrations (but seriously, do I have to lecture you again not to rack a slide from the front).

The gun’s overall length is 7.28 inches, overall height is 5.04 inches, and width is 1.10 inches. It has an empty weight of 18.48 ounces.

Glock G19 and G48
The Glock 19 (picture left) versus the Glock 48 (picture right).

This gun is a seriously sweet shooter.

The first magazine I put through I did a playing card drill – five shots fired at five yards, offhand, taking your time – and the group produced was an awesome single hole.

I got carried away and emptied the magazine, too, meaning all ten rounds nailed one hole. The G48 has eaten everything I’ve fed it which has been a combination of range and defensive ammo and has experienced no failures of any kind.

Mine is about 700 rounds in so far.

And yup…we got a full review of the G48 too.

3. G43, Gen 4

The G43 is a subcompact 9mm that came about back in 2015.

Although it was predated by the .380 ACP-chambered G42 it was met with far greater excitement. A single-stack 9mm from Glock was Big News at the time.

It’s a subcompact, little pistol and whether or not you like it tends to be a matter of strong opinion.

Glock 43 and magazine
The Glock 43 is a subcompact 9mm that’s a bit too small for my liking but does manage to outperform its similarly-sized peers.

I ran a G43 for the first time at the Glock media gun launch.

Glocks are my jam, but the G43 is a bit tiny for my hands. That said, a lot of gun owners love its size. It has an overall length of 6.26 inches, an overall height of 4.25 inches, and a width of 1.06 inches.

Empty it weighs in at 16.23 ounces. This is a highly concealable pistol but you do pay for that with a lower capacity; the G43 has a capacity of six rounds.

This is a good little pistol especially when you run it alongside its current competitors, the SIG P365 and Mossberg MC1SC.

After spending considerable time shooting all three, including time firing them one after another on the same days, I’m going to declare the G43 the most accurate subcompact 9mm.

It does have a shorter barrel – 3.41 inches –  so effective range is somewhat limited, but it’s accurate under ten yards. Out to fifteen yards groups broaden but are still good enough for self-defense.

If you want a subcompact 9mm that cycles reliably, beats out the competition for accuracy, and is perfect for concealed carry, you want the G43.

4. G20, Gen 4

Think of this as an honorable mention of sorts for those of us who handgun hunt.

The G20 is Glock’s full-size 10mm; the G29 is their compact 10mm. I’ve used my G20s on numerous hunts going after everything from alligators to deer to feral hogs.

Glock 20 with HP Ammo
Who doesn’t love 10mm?

Even caked with Texas dirt and clogged with rain they keep going. Considering the handguns I’ve had fail on dusty, dirty hunts I’m pleased the G20 does so well.

This one’s a substantially-sized pistol with an overall length of 8.07 inches, an overall height of 5.51 inches, and a width of 1.34 inches.

RDS Glock 20
Going prone is a good skill to hone whether or not you’re going to use your G20 to hunt.

When it’s loaded it weighs 39.86 ounces. I run mine with various red dots for hunting but I’ve also used them on the range and hunting with irons.

The Trijicon SRO, which is new at the time of this writing, has become a fast favorite of mine on my Gen 4 G20. It replaced the Trijicon RMR which is now living on one of my 1911s.

Glock 20 Target and Ammo
From a distance of 25 yards, shooting from the bench, with the SRO mounted to the gun the G20 nailed this group with Barnes 10mm 155 grain TAC-XP HP.

10mm came into being because the late Jeff Cooper decided he wanted a pistol cartridge with ballistics greater than those of the .45 ACP and more overall power than the 9mm.

It was FFV Norma AB that created it for Dornaus & Dixon Enterprises; the cartridge finally hit the market in 1983.

The cartridge’s final evolution exceeded Cooper’s initial ideas ballistically. When it’s loaded to its maximum SAAMI pressure it beats out .357 Magnum.

10mm produces a flatter trajectory and is capable of reliable performance at greater distances than its smaller caliber friends. It’s the sweet spot cartridge for handgun hunters. Oh, and it’s dead-on accurate, too.

Boom…want to get into 10mm? Check out our full review of the G20.

Honorable Mentions

There are a few other models worth a mention. For concealed carry there’s the G26, a subcompact double-stack 9mm with a ten-round capacity.

Crossbreed Holsters with G17, G19, G26
Crossbreed Holsters with G17, G19, G26

Its almost-twin, the G27, is chambered in .40 S&W, has a ten-round capacity, and is a neater little gun than you probably think possible.

The G42 is, of course, Glock’s single-stack, subcompact .380 ACP.

If that’s what you’re into, go for it. If you want a not-a-1911 .45 ACP there’s always the full-size G21 or the subcompact G30.

Parting Shots

In case you haven’t noticed yet – Glock has something for everyone.

There are reasons the Austrian company has flourished and those reasons include reliable cycling, durability, and affordable pricing.

Are they super-sexy? No, but you can change that with a little aftermarket work. It might be a cliché, but it’s true: you really cannot go wrong with a Glock.

    Hi guys, I have a question concerning the trigger set for G48. Unfortunately the mentioned Overwatch Precision TAC Trigger is not available in our country but I can buy this one. Do you think it is still worth buying? To be honest I have a problem with the grip a little bit and I´ve heard that the trigger upgrade might help. In fact, I am still shooting a little bit to the left. Nothing serious for defence purposes but I am still angry with that. I tested G48 with other friends and it looks like the "left" problem does not concern me only. Any opinions would be nice. Thanks a lot and have a great day, Martin

    People might think me crazy for saying but I'm a fan of the glock 22 ... not only is it a forty but I have 2 conversion barrels to change it to 9mm and one for 357 sig.. 150 for each barrel and for 450 dollars I bought the postols... but 750 $ and I have 3 guns in 1.. can't do that with but 2 glocks 22 and 23.. pretty sure..

    You kissed off the best carry gun as an afterthought -- the G42. With an ETS nine-round magazine and Xgrip shim you've got 10 rounds aboard a gun that barely weighs a pound fully loaded. The expanded magazine also provides a much better grip on a gun whose stock grip is too small for total control. Loaded with 90 gr. Underwood Ammo's Xtreme Penetrators from Daniels Defense at 1200 fps, the .380 ACP competes very favorably with 9mm. I wouldn't recommend the G42 for strolling around drug- and gang-infested neighborhoods but in my opinion 10 rounds should take care of thugs pretty much anywhere else.

    I have a gen 3 17 and a G42 love them both I’ve shot the G19, G43 and the G48. Loved the 19 and the 48. The G43 I found the trigger to be very uncomfortable to my finger due to the way it rubbed or possibly pinched my finger between the trigger guard and the trigger. I don’t notice it on my G42. I positively HATED Glock pistols when I shot my 1st one back in the late 1980’s. Probably a Gen 1, I don’t remember, but I thought it was as comfortable as a brick. When I took my carry class the instructor had a G19 that I was allowed to try. If there was a paradigm shift in a persons thinking, that was it. Sold!

    I recently got the Glock 45 Gen 5 and mounted a Holosun HE507C-GR optic on it. I have had several Glocks ( 21, 41, 43 and 17) but this one is my current favorite. The Holosun has been flawless so far, and I like the auto-on / auto-off feature, as well as the auto adjust lighting level. And green! Come on! Oh, and as an alternate platform to the 10mm G20, the Springfield XDM is worth a serious look.

      Yeah, after doing a ton of research on what my first weapon should be I ended up choosing the Glock 45 also. Basically because it's just a Glock 19 with better capacity. The longer grip works better for me too.

    the article says the 42 is a single stack. my 42 is a double stack. i always thought glocks were ugly and never planned to buy one but i was in the store looking to get a taurus spectrum last week and ended up taking home the glock instead. of all my 6 handguns the 42 is the most pleasurable and accurate to shoot at short distances.

    • David, PPT Editor

      Your G42 would be the only double-stack G42! Glock only produces the G42 in single-stack, the double-stack .380 pistol from Glock is the G25 and it is not sold in the USA. You might want to double-check your Glock ;)

    Was waiting with bated breath until I read your mention of the G20. You went and saved the best for last. Why settle for anything less? That said, I am looking to pick up a G21/45 upper and LW conversion barrels so I can shoot every major caliber out of this platform in the future. Doesn't hurt to have options. But if I find a G40/10 upper first, then I'm nabbing that, instead. Bring on Glockzilla! Options are overrated, anyway.

    so my daughter is a Federal Law Enforcement officer who scorned Glocks and preferred Sigs & HKs because of the double action. I bought a 23 for the wife and she thought it was a bit to much for her. My wive prefers the 19 so I left the 23 for my daughter to bring to the range and now even FLE officer admits the .40 is a pretty nice gun. I have to say though that daughter's p226 is also a nice gun.

    For my "duty firearm", I carry a Glock Mod 22 Gen 4 (.40 S&W cal.). It has good stopping power and it only slightly has more recoil. I barely notice it. For my "off duty" I carry a GLOCK Mod 27 Gen 4 (.40 S&W cal.), The difference in recoil between the 22 and the 27 is again in my opinion negligible. I do confess to having medium sized hands. I would not recommend it to women although the local Sheriff's Office does carry the GLOCK mod 22. As to the 9mm, It is a perfectly good round, now a day's as the advances in ballistics has advanced probably 10 fold. I do own both a GLOCK 17 and a 26 (Gen 4) which I have used for competition.

    I've been a 40SW fan since mid 80's and my first police trade in G23.....later added on a G27 for concealed, and recently the big G35...also have a major inventory of 40SW ammo so have leaned toward staying there. Recently bought threaded 9mm conversion barrels for the 23 and 35 along with extractors, etc. just to have less expensive range cost....but also to be diversified if 40 dried up....also to have good secondaries for my new Banshee in 9mm and suppressor. Just for grins, I also did a 357sig barrel for the 23....same mags..........hitting power and diversification

    Respectfully disagreeing, the FBI has recently concluded.on common sense... Bigger bullets cause bigger holes=people dying faster with less rounds. Fascinating concept. So logically without further ado, I suggest the Glock 21 SF(.45 ACP), Glock 41 Gen 4(.45 ACP), Glock 20 SF(10mm), and Glock 40 Gen 4. All used domestically, and internationally as not only Law Enforcement issued but as Military Special Operations as well. Not only does .45 suppress more effectively due to already being below the sound barrier, 9mm isn't stopping polar bear's anytime soon (10mm). If you want to be like the NYPD and carry a bunch of ammunition (9mm), shoot a bunch of rounds to overcompensate for your underpowered ammunition, miss a bunch of times due to having to shoot a volley of weaker rounds to no effect, and hit a bunch of innocent people... Then by all means 9mm. Just look up every organization, department, agency, regiment, division, company, squad ect. that has come out against, or completely moved away from 9mm for lack thereof. Don't believe professionals? Look up wound tracks and cavities for the .45 ACP and 10mm compared to any 9mm. The instilling of common-sense unto the ignorance of masses uneducated on the topic of my profession is complete.

      That's why the FBI decided money beats performance, and went back to the 9. That way, when they are on their cell phones begging bad guys to surrender, or telling the bad guys to run and hide from Republican professional law enforcement, the 9mm won't over burden their pants..
