Are All Walther P99 Magazines The Same?
The magazines included in this review differ in a few aspects. The most basic of them being the capacity and caliber. Additionally, while some mags feature a simple stainless steel design, others can have a nickel-plated finish with windows for tracking ammunition. Magazines differing in caliber and capacity will also have different sizes to accommodate the respective ammunition.
However, all the items included in this review have several common features as well. For example, all magazines are made from stainless steel, have a polymer follower and a high-quality steel spring. It is also important to note that blue colored followers tend to be more stable and less tilt-prone compared to black or red ones.
What to Look For When Buying a Walther P99 Magazine
These are the most common focuses buyers have when shopping for their next mag:
Durability and Finish
While P99 magazines are always manufactured from stainless steel and you won’t find a polymer variant. It is important to consider the quality of an item. Magazines tend to be dropped and stepped over a lot, especially during training and range sessions. Which can cause deformities resulting in serious jamming issues. A good way to identify quality is to purchase mags from Walther or trusted manufacturers like Mec Gar.
Good Follower and Baseplate
You’ll notice the color of followers on different items to be different. While some feature a blue color, some are black or orange. The blue followers are the latest upgrade to P99 magazine and are more stable than other versions. Similarly, check the baseplate for easy disassembly and finger rest.
Witness Holes
Witness holes are small circular holes on the side of the magazine which allow you to track the number of rounds left in the magazine. These can also come stamped with numbers for better inference. Witness holes are an important feature with extended and normal capacity magazines. Especially if you are stuck in a SHTF situation.
Capacity
Walther P99 items come in a variety of different sizes. Ranging from 10 rounds to 20 rounds. Extended magazines are viable for practice and plinking but tend to be heavy and difficult to carry. You must choose a magazine based upon your intended applications.

Pros
Cons

Why it Stands Out to Us

Who Will Use This Most
The item is purely intended for range use and fun shooting. Although some adventurous users can also find it to be a viable home defense gun with a rifle’s ammo capacity. The extended length and weight of this magazine make it clumsy to maneuver. Which in turn limits its applications.
Bottom Line

Pros
Cons
What Recent Buyers Report
Users report this item to be flawless and appreciate the high-quality metal construction. The mag fits perfectly and the price point is also an impressive factor for the buyers. Being a genuine Walther magazine, the badge of credibility and user support is also associated with this magazine.
Why it Stands Out to Us
The product has been manufactured by Walther which assures the quality and perfect fit with the P99. The 15 round capacity is more than the normal 10 rounds and makes the magazine suitable for multiple purposes. Additionally, the stamped witness holes help the user to conserve and track ammunition.
Who Will Use This Most
The item is perfect for self-defense and EDC. Especially by on-duty officers. The witness holes allow the user to track the ammunition quickly in the middle of a dangerous situation. Additionally, the magazine is great for range use and practice as the shooter doesn’t have to reload very often.
Bottom Line

Pros
Cons
What Recent Buyers Report
The 16 round P99 magazine has been widely appreciated by its users. People like its quality construction and flawless action. Plus it holds 16 rounds at full capacity as advertised by the manufacturer. Another very appreciated factor among buyers was the price of this magazine.
Why it Stands Out to Us
A cut above than the previously mentioned 15 round mag. This 16 round magazine lets you carry one extra round and eliminates the need of adding a grip extension to the 15 round magazine. Additionally, the magazine saves you money you’d rather spend on buying extensions or separate mags.
Who Will Use This Most
The magazine is perfect for people who like to carry extra ammunition without adding the bulk of multiple backup magazines. That extra round is a boon for panicky people who spew out bullets like a machine gun in a SHTF situation. Plus, the magazine is also good for range use and training.
Bottom Line
The Walther 16 round magazine is an OEM product that assures its quality. The magazine fits and functions flawlessly. Having an extra round in the magazine won’t hurt, especially if the magazine is not burning a hole through your wallet.

Pros
Cons

Why it Stands Out to Us
This magazine is a reliable replacement or backup for the P99 OEM magazine since it has been manufactured by Walther itself. The impeccable finish of the magazine and the witness holes on the sides are quite helpful. Plus the sturdy base plate with a finger rest helps with handling.
Who Will Use This Most
This magazine is ideal for target practice and tactical drills. Additionally, the magazine can also be carried as a backup if you use a Walther P99 for active duty or self-defense. The flush fit and finger rest of the magazine makes it a viable component for training as well.
Bottom Line

Why it Stands Out to Us
This P99 12 round 40 S&W magazine is not very prevalent in the market. However, it still is a very viable addition to the P99, given its high capacity of the powerful 40 S&W calibers. The quality construction and reliable feeding of this magazine makes it a trustworthy component for all applications.
Who Will Use This Most
The capacity and caliber of the magazine make it ideal for on-duty officers and self defense. The 40 S&W is a powerful round with amazing stopping power.
