When it comes to the .40 Smith & Wesson vs. 9mm there is an endless debate raging.  There are benefits why each is better, but here we are going to talk about the .40 chambered Glocks.

The models are strikingly similar to the 9mm models, so the size isn’t really the differentiator here; it’s the number of rounds they can hold and the larger caliber.  Well, that and the fact that Glock isn’t making a single stack .40 like they have in the Model 43.

A lot of people swear by the .40, including many law enforcement and government agencies.  It’s that happy medium between the .45 and the 9mm in terms of size, weight, stopping power, and how many rounds you can carry in a single magazine.

When it comes to the different Glock models, each has its place.  Most of the calibers have 4+ variations that offer different features and sizes to fit your needs and use.

Some of the pretty common uses are concealed carry, competition shooting, and service pistol.  When it comes to the different models, they all pretty much act the same but the different physical size can help with certain aspects of the duties you’re asking it to perform.  For example, the long slide is a better competition pistol than the Glock 27.

Below is a rundown of the specific models and the areas where they excel.

A Note About the Gen 4 Models

The generation 4 models of the Glocks below all have the same upgraded components.  These are what you will see when you go to your local gun store, but you can still find some of the other variants if you look.  The added texture, magazine catch, spring, and back strap are all great and why the Gen 4 models really took off.

Glock 22 – Full Size

In 1990 the Glock 22 was introduced.  This full-size Glock was made because there needed to be something between a .45 and a 9mm.  Because of its usefulness and reliability, many police and government agencies adopted this model as their service pistol.

Glock 22, Gen 4

The Gen 4 version of the Glock 22 made some big changes to the cosmetics and functionality of the original.  Based on feedback from the original Glock 22 users, a texture was added to the Gen 4 to make it easier to grip.  Another major Innovation was the backstrap.  This allowed users to customize the thickness of the grip for their hand size.

Internally, the Glock 22 Gen 4 had a new dual recoil spring assembly that helps keep the gun shooting for a lot longer than its predecessor.  Glock also added an accessory Rail and a larger magazine release that you could change for either left or right-hand shooters.

The model 23 is a great go-to Glock if you want a compact concealed carry weapon, or if you have smaller hands.  Having the accessory rail on the Gen 4 version lets you add a light or other add-on.

Glock 24 – Long Slide

The Glock 24 ($715) is what they call a long slide.  Basically has a longer barrel than a similarly sized handgun would. The whole reason for the longer Barrel is a for accuracy.  That’s why this and the Glock 35 are used for competition shooting.

When researching this article, it was difficult to come across many places that sold the Glock 24.  I think it’s a little more uncommon than other models, even the Glock 35.

Even though it has a longer Barrel, it’s still a pretty compact design.  This lets you carry it like you would a full-size weapon even though it has a smaller handle and magazine capacity than the full-size Glock 22.

Why You’d Want It

The model 24 is a long slide so it’s a bit more accurate and is used as a competition shooter.  It’s not so large, though, that you can’t use it for your daily carry weapon.

Glock 27- Subcompact

Glock 27 is the subcompact of the group.  A lot of police tend to carry it as a backup weapon.  It’s small, fairly lightweight, and packs a punch.  Having the 9+1 capacity is really helpful when you need it.  Armed citizens like to use it for their concealed carry weapon.

The Glock 35 Gen 4 offers the same features as the other Gen 4 models, but you get the only Glock .40 caliber model has that is MOS (Modular Optic System) configuration.  If you wanted to add a reflex optic to your Glock, you need a model like this.  Otherwise, you need to have the slide machined to accept the optic.

Which Type of Glock Is Right for You?

Glock has such a wide array of models and calibers, there is a model for everyone.  The trouble you’ll have is choosing the model that best fits your needs or wants.  You already have a caliber in mind, but selecting the specific model can be a little daunting.

Where to Start

Starting out, I would look at the Glock 23.  This is based on the popularity of the 9mm version, the Glock 19.  The sizing is great for almost everyone, it’s easy enough to conceal, yet big enough to open carry of you’d prefer.  The Gen 4 model lets you customize the fit of the grip to your hand even more.

Safe Action

Something to remember, all the Glocks talked about here have the Glock Safe Action safety.  While to the uneducated it may seem like it’s not really a safety, it’s actually really secure.  Take a look at this diagram from Glock.

The .40 S&W Glock, no matter the version, will give you the world renown Glock durability in any environment.  You can bet your life on its reliability because it has been proven in the field year in and year out with law enforcement and government agencies using them.

I carryy a 22 on duty w a 27 as back up. For some reason I shoot the heck out of the 27. Let’s see +p a .40…..9 is ok, I will stick with the .40. .40 is an excellent compromise without having to +P it. Don’t get me wrong I can really shoot the heck out of a G17, but that’s not what I am allowed to carry, so I keep it simple and stick to what I am training with. End of the day, carry what you train with and shoot well. Off duty I carry either gun.… Read more »

Well, OK, I’ll bite.

I’m unaware of any genuinely qualified subject matter expert who still thinks the 40SW is a better choice than the modern 9mm JHP or 9mm JHP +P rounds now available.

But … carry on. Nothing like a good caliber debate to watch.

I’ll make the popcorn.

I think .380 is the best caliber for self-defense and combat and I will viciously argue with anyone who things otherwise.

I also enjoy popcorn 😀
