First Impressions of Tactical Precision Manufacturing TPM Sig P320/X5 Legion 3 Round Extension
The Tactical Precision Manufacturing TPM Sig P320/X5 Legion 3 Round Extension promises enhanced capacity, faster reloads, and improved magazine handling for the already stellar Sig Sauer P320 platform, particularly the X5 Legion. I’ve spent over a decade tweaking and optimizing tactical gear, and the P320’s modularity always intrigued me. This extension seemed like the perfect, relatively inexpensive upgrade to push my P320’s performance even further.
My primary motivation for seeking out this particular magazine extension was simple: increased capacity without sacrificing reliability. Standard capacity magazines are great, but a few extra rounds can make a difference in a competitive or defensive situation. I wanted a solution that was robust, aesthetically pleasing, and wouldn’t compromise the ergonomics of my P320.
The Tactical Precision Manufacturing TPM Sig P320/X5 Legion 3 Round Extension arrived in a simple package, showcasing the extension itself. The machining immediately caught my eye; it appeared clean and precise, with a smooth, even finish. The weight felt substantial, suggesting a durable build, and the color, a matte black, looked like it would seamlessly integrate with my existing P320 magazines.
I considered several other magazine extensions before settling on the TPM model. Some were made of polymer, which I worried wouldn’t stand up to heavy use, and others were significantly more expensive. I chose the Tactical Precision Manufacturing TPM Sig P320/X5 Legion 3 Round Extension because it seemed to offer the best balance of quality, price, and positive user reviews.
My initial impression was one of cautious optimism. The fit and finish seemed excellent, but the true test would be how it performed in live-fire drills. The promise of increased capacity and faster reloads was exciting, but I needed to see if it lived up to the hype.
Real-World Testing: Putting Tactical Precision Manufacturing TPM Sig P320/X5 Legion 3 Round Extension to the Test
First Use Experience
My first outing with the Tactical Precision Manufacturing TPM Sig P320/X5 Legion 3 Round Extension was at my local outdoor range, a dusty and somewhat unforgiving environment. I brought along a selection of my P320 magazines, including 15, 17, and 21-round variants, to test compatibility. I also planned to run several drills focusing on speed reloads and malfunction clearing.
Installation was straightforward, requiring only a few minutes per magazine, and the extensions locked securely into place. The added length of the magazine provided a more positive grip during reloads, and I immediately noticed a difference in my handling speed. I ran several magazines through my P320, focusing on rapid fire and controlled pairs.
Initially, I experienced no malfunctions or feeding issues with the extensions. The magazines locked in positively, and the pistol cycled flawlessly, even when intentionally limp-wristing to induce a potential failure. The only slight issue was a bit of extra friction when seating the magazine on a closed slide, but that quickly resolved itself after a few repetitions.
Extended Use & Reliability
After several months of consistent use, the Tactical Precision Manufacturing TPM Sig P320/X5 Legion 3 Round Extension has proven to be remarkably durable. I’ve used them in various training scenarios, including force-on-force simulations and low-light drills. The extensions have been dropped on concrete, exposed to rain and mud, and generally subjected to the rigors of real-world use.
Despite the abuse, the extensions show minimal signs of wear and tear. The finish remains intact, and there are no cracks or deformation of the aluminum body. Regular cleaning is simple, requiring only a quick wipe down with a damp cloth and occasional lubrication of the magazine body.
Compared to other magazine extensions I’ve used in the past (mostly polymer models on other platforms), the Tactical Precision Manufacturing TPM Sig P320/X5 Legion 3 Round Extension stands out for its robustness and reliability. I’ve had polymer extensions crack or break under similar conditions, but the TPM extensions continue to perform flawlessly. These extensions have definitely exceeded my expectations.

The extension seamlessly integrates with the existing magazine, maintaining the reliability and feeding characteristics of the original design. I experienced no issues with misfeeds or failures to extract when using the extensions. This is a testament to the quality of the design and manufacturing.
The only minor drawback is the slight increase in magazine length, which may make it more difficult to conceal carry.
