To the average American, owning a firearm is just as important as possessing an automobile. The United States Constitution has given Americans freedom to own firearms under the second amendment. The main purposes for having guns are hunting, self-defense, and sportsmanship. There are many types of guns ranging from pistols to rifles to shotguns. All different types of guns have different characteristics, sizes, and prices. It is important to know what type of gun you need before purchasing one. Here is a comparison of Glock 42 vs LCP.

The Glock 42 is a single stack subcompact chambered in .380 ACP, which is one of the most popular cartridges available. This gun has a magazine capacity of six rounds.  This is a good amount of firearm ammunition, but customer opinions vary on how much firepower is required for self-defense. The LCP pistol was released in 2008 and quickly became popular with shooters looking for a small concealed carry pistol. This gun weighs 9.6 ounces and has an external hammer that does not require the gun to be cocked to fire. The magazine capacity is six rounds. This gun is also chambered in .380 ACP, which further enhances its popularity among gun buyers.

Features of Glock 42 Vs LCP

Grip and Textures

One of the reasons for Glock’s success is its unique grip, which feels like an extension of your arm. The Glocks shoot naturally and accurately because it fits your hand like a glove. Glocks are available in both full size models and compact models such as the Glock 26 and smaller compact models such as the Glock 42.

The LCP is designed with a small frame and fixed sights. This design makes it easy to conceal, but some shooters complain that this gun feels like holding a bar of soap because the textured plastic on the grip causes discomfort after long periods of shooting.

Size and Weight

The Glock 42 weighs 13.76 ounces unloaded and has an overall length of 5.94″. Its barrel is 3.25 inches long and the height is 4.13 inches tall, which is slightly larger than most compact models such as the Ruger LC9, but smaller than full-size models such as the Smith & Wesson M&P 9. The LCP weighs in at just 9.6 ounces and has an overall length of 5.16″, with a barrel length of just 2.75 inches long and a height of 3.6 inches tall, which is significantly smaller than the Glock 42.

Trigger Mechanism

Glock’s Safe Action trigger system prevents accidental discharge by requiring a three-point pressure from the user. The trigger must be pulled, depressed, and released before firing the pistol. It is important to always maintain a firm grip on your Glock 42 to prevent negligent discharges. Customer opinions vary as to how well this trigger mechanism works compared to traditional trigger mechanisms, such as the double action/single action on the LCP.

Glock 42 Trigger Mechanism

The LCP has a double-action only trigger mechanism that requires more trigger pressure to fire the gun compared to the Glock 42. This is because it uses an external hammer and does not have any built in safeties like what is featured on Glock’s Safe Action trigger system. Also, the LCP’s slide will remain open after all rounds have been fired from the magazine. This can pose a problem if you need to rapidly fire multiple follow up shots but find yourself without a round in the chamber because a fresh magazine must be inserted before you can continue shooting.

Magazine and Ammunition Capacity

The Glock 42 is chambered in .380 ACP, but customer opinions vary on how effective this cartridge is compared to other calibers. Some claim that the .380 ACP only offers minimal stopping power because it lacks velocity, while others have no issues with accuracy or stopping power. The LCP also uses the .380 ACP cartridge, which is inferior to other cartridges such as the 9mm Luger cartridge.

Glock 42 Magazine and Ammunition Capacity

This cartridge only offers to stop power when using the hollow point rounds, which expands upon impact and creates a larger wound cavity compared to full metal jacket rounds. The .380 ACP is also one of the smallest centerfire pistol calibers available on the market today, which limits your ability to make fast follow-up shots in a self-defense situation.

Shooting Accuracy

The Glock 42 has an overall length of 5.94″, whereas the LCP’s overall length is 5.16″. Because of this, the Glock 42 should offer better accuracy when compared to the LCP.

Cost and Value

The Glock 42 costs approximately $400, which is a good price for a compact semi-automatic pistol with proven accuracy, durability, and reliability. The LCP offers similar performance at only about $350 less than the Glock 42, making the LCP a good bargain for shooters on a budget.

Safety Mechanism

The Glock 42 has a slim profile that makes it difficult to conceal, especially for individuals who are not used to carrying concealed weapons. This design also results in the lack of an external safety mechanism. Both models have safety mechanisms located on their respective slides, but customer opinions vary when it comes to how well these safeties work compared to traditional safeties, such as those located on the actual grip of the pistol. The best gun for you will depend on your needs and preferences as a shooter. It’s important to practice regularly if you own either model because you never know when negligent discharges may occur.


The Glock 42 is one of the most popular concealed carry pistols on the market today, which can pose a design issue when it comes to concealability. The slim profile and lack of an external safety mechanism allow the biggest advantage in concealing this model. Customer opinions vary regarding how easy it is to carry either model concealed. Some claim that you can easily tuck the LCP into your waistband using an IWB holster, while others experience too much printing when trying to conceal the Glock 42.

Durability and Reliability

The Glock 42 has an infamous track record when it comes to durability and reliability, whereas the LCP’s record is relatively clean compared to most other compact pistols on the market today. However, there are varying opinions regarding the durability and reliability of both models, but it is safe to say that any problems can usually be traced to improper maintenance and use. Some claim that both are equally durable, while others have experienced issues with the slide locking back on the Glock 42 after only a few hundred rounds fired.

Slide and Barrel Length

The Glock 42 has an overall barrel length of 3.25″, which is longer than the LCP’s overall barrel length of 2.75″. This results in better accuracy, velocity, and range when compared to the LCP model. This advantage could become a disadvantage for shooters who are looking for a small pistol to conceal because added barrel length makes it more difficult to do so.

Aftermarket Accessories - Glock 42 Vs LCP

Due to the popularity of the Glock 42, arguably the most popular compact pistol on the market, there are many different aftermarket accessories to choose from. Some common examples include lasers, flashlights, holsters, grips, and more. Both models offer a large selection of aftermarket accessories to choose from if you’re looking for ways to customize your experience.


The LCP offers adjustable rear and front sights, whereas the Glock 42 does not. Both models come with basic ramped sights that are difficult to see in low light situations and often need replacement to provide a good sight picture. There are also several different sight options for either model that you can choose from like fiber optic sights and night sights. Night sights are generally preferred by shooters because these sights glow in low light conditions allowing you to get a good sight picture even without visualizing the front and rear sights.


However, night sights can be an issue with concealed carry pistols because of their added height that interferes with a smooth draw from a holster. Fiber optic sights have the opposite advantages and disadvantages compared to night sights, so consider this when deciding which modification is right for you.


The Glock 42 has one of the most customizable grip profiles on the market today, which makes it easy to find a factory replacement or aftermarket grip that feels comfortable in your hand. There are also over 70 different grip options available with varying textures and contours for enhanced control during use. The LCP is a smaller pistol, so it’s not as customizable as the Glock 42. However, there are multiple grip options available for this model that provide varying degrees of comfort and control.

Magazine Extender 

It’s not uncommon for shooters to find that both of their hands don’t fit comfortably on a compact pistol like the Glock 42 or the LCP. The LCP model comes with built-in finger grooves on the front of the grips so, some shooters may find this feature sufficient to create more space between their hand and the grip. The Glock 42 doesn’t come with built-in finger grooves, but there are aftermarket extenders that you can purchase separately which increase your gripping surface area.

Magazine Loader  

Magazine loaders are a great way to speed up the process of loading ammo into your magazines. Both models come with their respective factory magazines, but those will only hold six rounds each for the Glock 42 and six or seven rounds for the LCP depending on which magazine you buy. In all honesty, you’ll probably find it much easier to load ammo into your magazines using a magazine loader than manually loading each round by hand.


The holsters are durable and reliable, but they can also pose issues when it comes to concealability depending on your body type. Both models should come with a belt holster, but there are other types of holsters like shoulder holsters, ankle holsters, pocket holsters, inside the waistband (IWB) holsters, and more that you may consider for extra concealability. The Glock 42 is a popular pistol for concealed carry, so it has a wide variety of holsters to choose from. However, there are fewer options available when choosing a holster for the LCP model.

Yes, the Glock 42 is a great option for concealed carry. It’s small enough to fit in your pocket or your waistband, but it’s large enough to have a confident textured grip and an easy rack on the slide.

The Glock 42 is a great choice for anyone who’s looking to purchase their first self-defense pistol because it has many of the same features as the well-known Glock 43 but at a much lower price point. The Glock 42 is reliable and accurate, which makes it an excellent backup gun or nightstand gun as well as a good concealed carry gun.

The Glock 42 has a lot of competition in the compact semi-automatic pistol market, but the closest alternative to this model would be the Ruger LCP. Both models are great for concealed carry applications, and their factory standard holsters work well with the model they’re designed for.

Yes. Pocket holsters often work best when you’re carrying a smaller sized gun like the LCP, and they also provide an easy way to maintain safe muzzle control while drawing your firearm in public places where it’s not always appropriate to show off.


Both the Glock 42 and the LCP are dependable pistols that are excellent for concealed carry purposes. The main differences between these two models are size, weight, price point, customization options, grip texture/contour, adjustable sights, magazine extenders, magazines included with purchase, and accessory compatibility. The reasonable price point of the Glock 42 makes it a great choice for someone who’s looking for their first self-defense pistol. However, shooters with larger hands may find the LCP more comfortable to use because of its smaller grip size and lighter weight.
