Description
This 17-round Mec-Gar magazine is built specifically for Tanfoglio Witness large-frame pistols in .38 Super. The tube is constructed from certified carbon steel that's TIG welded and finished seamlessly, then heat-treated for strength and durability. You get a high-impact polymer follower that keeps rounds feeding smoothly and a flush-fit polymer floor plate that seats cleanly in the magwell.
The anti-friction coating is what makes a real difference during extended shooting sessions. It reduces friction when loading and unloading, which means faster mag changes and less wear on the spring and internals over time. The coating also provides excellent anti-corrosion protection, keeping your magazine reliable whether you're at the range, in competition, or training.
Mec-Gar has been the go-to magazine manufacturer for major firearm brands including Sig Sauer, Walther, Browning, and Remington for decades. They manufacture both their own line and OEM magazines for some of the biggest names in the industry. This is the same level of quality you'd expect from factory magazines, but at a more reasonable price point.
If you run a Witness in .38 Super for competition, training, or general practice, having multiple quality magazines is essential. This replacement mag works great alongside original magazines or as a full set for extended range trips.
