First Impressions of SIG SAUER M17 P320 21 Round Extended Pistol Magazine
The SIG SAUER M17 P320 21 Round Extended Pistol Magazine promises increased capacity for two of SIG SAUER’s most popular platforms. As someone deeply invested in both the P320 and tactical preparedness, the allure of extending my firepower was strong. This isn’t just about more rounds; it’s about potentially mitigating the need for reloads in critical situations.
Years back, during a force-on-force training exercise, I found myself fumbling for a reload at the worst possible moment. That situation underscored the value of every single round. The SIG SAUER M17 P320 21 Round Extended Pistol Magazine seemed like a practical solution.
Upon unboxing, the magazine felt solid and well-constructed. The black finish matches my M17 perfectly, and the weight provides a sense of durability. It’s immediately apparent that this isn’t some cheap aftermarket add-on, but a genuine SIG SAUER product.
Compared to standard 17-round magazines, the extended length is noticeable but not unwieldy. I had considered other extended magazine options, but opted for the SIG SAUER model due to its reputation for reliability and guaranteed compatibility. My initial reaction was positive; the magazine felt robust and ready for action, promising increased capacity without sacrificing quality.
