M3 vs M7 Shoulder Holster Explained

One of the best things about owning a gun is being able to take it out of its safe and use it at any time to protect yourself, your family, or your property. You may have your favorite gun, but not every gun you carry can be your “go-to” gun. If you’re looking to add another firearm to your arsenal, you need to know which holster will work best with that specific gun.

The two most common types of shoulder holsters are the M3 and the M7. These are made from various materials, which will affect the fit and feel of the holster. It’s important to understand what these are and how they differ before buying one for yourself.

Overview of M3 shoulder holster

The M3 shoulder holster is a holster made with leather and special fabric that absorbs moisture and is soft to the touch. It’s designed for comfort and provides a firm hold. It’s ideal for law enforcement and tactical operators who need a secure grip when they carry their guns.

The problem is that most of us don’t have the extra money to buy a holster with lots of extra features. This is why the discrete M3 holster comes in a compact size. The only difference is that it has some extra features such as a belt clip and a built-in lanyard. In fact, it’s the best holster in its price range. That’s why a discrete M3 holster is the best holster for a concealed carry weapon. It’s the only holster I recommend for people who need to carry a gun without being noticed.

Difference Between M3 vs M7 shoulder holster

M3 has a simple design, with two shoulder straps that attach to a single belt loop. It’s super comfortable and lightweight, so you can forget it’s even there.

2. M7 is made to fit snugly around the shoulder blades and has three side-by-side shoulder straps and a strap at the back.


Both the M3 and M7 shoulder holsters are quite similar, but each of them has its advantages and disadvantages. They both offer a comfortable fit and minimal movement of the handgun.

The main difference between the two is the size of the holster. The M3 is smaller than the M7, which makes it more suitable for concealed carry. However, this smaller size also means that it can be more difficult to remove a gun from the holster, so if you don’t want to keep the gun in your pocket or purse all the time, then the M3 is not the right choice for you.

If you’re looking for a holster that allows you to wear your weapon at all times, then the M7 is the better choice, as it is bigger and therefore easier to remove the handgun.


If you’re looking for a shoulder holster that can be concealed easily and quickly, then the M3 or M7 is definitely your best bet. These holsters use the ‘M3’ or ‘M7’ design, which has been popularized by the military but can be used for a variety of purposes.

As these are custom made, they are expensive.

So make sure to get a holster that will fit you perfectly, before you spend your hard-earned money.


If you’re looking for a shoulder holster that will stay on you during long gigs or rehearsals, or if you want a discreet and comfortable way of carrying a handgun, then we recommend the M3 shoulder holster, as it has proven itself time and time again.

The M3 holster is made from ultra-high quality nylon material and has been ergonomically designed to fit your shoulder perfectly, making it extremely comfortable.

The retention strap is made of heavy-duty webbing, and the holster can be easily adjusted to fit your body size and style.

Unlike the M7, the M3 is very easy to use – it’s quick to put on and take off, with no complicated buckles or zippers to deal with. The M3 also fits a wide variety of handguns – from small subcompacts to full-size 1911s – and is compatible with a wide range of holsters.


Choosing the best shoulder holster depends on how comfortable you want your gun to be.

While the M3 is the more common choice, the M7 offers additional features like an integrated magazine pouch and a double-layered holster design. The latter also keeps your gun concealed, which is especially useful for women.

Ease of Use

In general, shoulder holsters are easier to use than waist holsters, but they also have their downsides. In this article, we compare the ease of use and comfort between two of the most popular shoulder holsters – the M3 and the M7.

Shoulder holsters come in three categories: single, double, and hybrid. Single shoulder holsters are the most common and are used by most people, but their single strap makes them difficult to wear over the shoulder if you have a larger bust. Double shoulder holsters offer a better fit and are more comfortable to wear. Hybrid shoulder holsters combine a single strap with a double belt and are the most comfortable to wear.

The M3 and M7 are both hybrid shoulder holsters, and they have similar features that make them suitable for most people. Both of them are easy to put on, but they differ in comfort. The M3 is generally considered to be more comfortable than the M7, due to its smaller size.

Men or Women

The M3 and M7 shoulder holsters are the two most popular shoulder holster options in the market today. The main difference between these is that the M7 has a longer barrel, which makes it ideal for larger-framed men.

In addition, the M3 holster is more discreet than the M7. It’s also easier to adjust, with the only two positions being a cross draw and vertical carry, which makes it comfortable for women.

So what should you pick? It’s all about your comfort and preference, so it’s important to consider all the factors. You may find the M7 holster to be too large for your frame and prefer the M3, or vice versa.

It’s also important to consider how you intend to wear the holster. If you intend to wear it with a jacket, you’ll need a smaller holster. Similarly, if you intend to wear it with a t-shirt, you’ll need a larger one.

The main factors in your selection will be the size of your frame and the intended location of the holster on your body.

The M3 is a slightly larger holster than the M7, so you’ll be able to comfortably carry it in a bigger variety of sizes. This is important because the M3 isn’t really the smallest holster available, and carrying around a large-sized holster can be difficult.

So if you’re looking for something that’s a little smaller and a little more comfortable, the M7 is definitely your best option. If you have a bigger chest or larger arms, the M3 might still be the better choice for you.
