First Impressions of Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension
The Glock 20. A beast of a handgun chambered in the potent 10mm Auto. While its 15-round capacity is respectable, sometimes you need just a little bit more. That’s where the Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension comes in, promising to add those crucial extra rounds while enhancing reload speed and overall functionality. I’ve always felt the Glock 20’s grip was a touch short for my hands, and this extension seemed like a perfect solution to both increase capacity and improve ergonomics.
My search for a reliable mag extension was driven by a series of frustrating experiences during wild hog hunts. Running dry at a critical moment can be, shall we say, unpleasant when facing a charging boar. I needed a solution that was both durable and guaranteed flawless feeding under pressure.
Upon receiving the Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension, I was immediately impressed with its heft. Machined aluminum felt solid and reassuringly robust. The finish was clean and even, suggesting quality craftsmanship. I’ve used extensions from Pearce Grip and Strike Industries in the past. I ultimately chose the TPM extension because of its promise of improved functionality beyond just adding capacity, and its reputation for ruggedness.
My initial reaction was definitely positive. The Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension felt like a serious piece of kit, not some cheap add-on. This sparked a blend of excitement and anticipation to test its functionality and reliability in the field.
Real-World Testing: Putting Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension to the Test
First Use Experience
I first tested the Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension at my local outdoor shooting range. Conditions were dry and sunny, perfect for evaluating the extension’s performance. I ran several magazines through my Glock 20, focusing on reload speed and observing any feeding issues.
The increased grip length was immediately noticeable, offering a more secure and comfortable hold. Reloads were noticeably faster due to the extended base providing a larger target for my support hand. However, I did experience one failure to feed during the first magazine, which I attributed to the magazine spring not fully settling with the added capacity.
Extended Use & Reliability
After several weeks and hundreds of rounds, the Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension has proven to be remarkably durable. There are no noticeable signs of wear and tear on the extension’s finish. I have used it in varying weather conditions, including a particularly muddy hog hunt, and it continues to function reliably after a quick cleaning.
The extension is very easy to clean; a simple wipe-down with a cloth is generally sufficient. Compared to the OEM baseplates, I find this extension provides a more positive grip during magazine changes, especially with gloves on. Its performance has far exceeded my initial expectations, save for the initial hiccup with the magazine spring seating.
Breaking Down the Features of Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension
Specifications
The Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension is crafted from machined aluminum, ensuring strength and durability. It’s specifically designed for Glock 20 and Glock 40 pistols chambered in 10mm Auto. The extension adds 3 rounds to the magazine capacity. It comes in various colors to allow for customization.
The TPM extension’s aluminum construction is crucial for handling the high pressures of the 10mm cartridge, ensuring structural integrity and resisting deformation. The added capacity, while seemingly small, can be a game-changer in defensive or hunting situations. The available color options are a nice touch, allowing you to personalize your firearm.
Performance & Functionality
The Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension performs admirably in its intended role. It reliably adds capacity, improves reload speed, and enhances the overall grip of the Glock 20. Its primary strength lies in its robust construction and ease of installation.
However, it does rely on the stock magazine spring, which, as I discovered, might need some break-in time to function flawlessly with the added capacity. This is something Tactical Precision Manufacturing could improve by including an uprated spring in the package. Overall, it meets and slightly exceeds expectations, providing a noticeable improvement over the factory baseplate.
Design & Ergonomics
The Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension features a streamlined design that seamlessly integrates with the Glock 20 frame. The machined aluminum feels solid and provides a comfortable grip. The added length improves the overall ergonomics, especially for those with larger hands.
While the design is generally user-friendly, some users with smaller hands might find the extended grip slightly less comfortable. The installation is straightforward, requiring only a punch or similar tool to remove the factory baseplate. The overall build quality is excellent, and the weight is negligible.
Durability & Maintenance
The aluminum construction of the Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension suggests excellent long-term durability. After months of use, it shows no signs of cracking, bending, or significant wear. Maintenance is simple, requiring only occasional cleaning to remove dirt and debris.
Given its solid construction, this extension should last for many years with proper care. The finish is resistant to scratches and corrosion, further enhancing its longevity. Simple cleaning with a brush and solvent is all that is needed to maintain the extension.
Accessories and Customization Options
The Tactical Precision Manufacturing TPM Glock 10MM 3 Round Mag Extension doesn’t come with any included accessories beyond the extension itself. However, it’s compatible with most aftermarket magazine pouches designed for Glock 20 magazines. While it doesn’t directly support optics or other firearm accessories, the improved grip can indirectly enhance shooting performance.
Tactical Precision Manufacturing offers the extension in multiple colors. This enables users to match the extension to their Glock’s frame or slide. There is no official support for different grip textures or specialized springs, but the aftermarket community is likely to provide some solutions.
