Description
If you run a Witness or Tanfoglio small-frame 9mm, you know factory magazines can be hit or miss. This Mec-Gar upgrade solves that problem. You get 17 rounds of capacity instead of the typical 16, and it still sits flush with the pistol frame when fully loaded. No printing, no bulge.
The construction is solid. The tube is certified carbon steel with a heat-treated finish for durability. Inside, you get a high-tensile music wire spring and a high-impact polymer follower that won't wear out after thousands of cycles. The base plate is polymer too and engineered to sit flush. An anti-friction coating on all surfaces means the rounds slide in smoothly when loading by hand or with a loader, and it cuts down on corrosion.
Mec-Gar built these the way they've been building magazines for decades. They supply OEM mags to Sig Sauer, Walther, Browning, and other major manufacturers, so they know what reliability looks like. This magazine works for range days, competition, or carry. Get a couple spares if you're putting rounds downrange regularly, or use this as a drop-in replacement for worn factory mags.

Frequently Asked Questions
Will this magazine fit my Witness pistol?
This magazine is made for small-frame Witness/Tanfoglio 9mm pistols. Make sure you check your frame size first – Witness made a running change to frame sizes around 2005, and the small frame and large frame magazines are not interchangeable. If you own a pre-2005 model or one specifically labeled small frame, this will work.
How many rounds does it hold compared to the factory magazine?
This holds 17 rounds, which is one more than the typical factory small-frame magazine capacity. The difference is you still get a flush fit with the frame, so you're gaining capacity without the mag sticking out.
What's the anti-friction coating for?
The anti-friction coating makes rounds load smoothly when you're topping off the mag by hand or using a loader. It also helps protect the steel from rust and corrosion, which extends the life of the magazine.
Is this a factory or aftermarket magazine?
Mec-Gar manufactures OEM factory magazines for major brands like Sig Sauer, Walther, and Browning. This is a Mec-Gar branded magazine designed specifically for Witness/Tanfoglio pistols. It's built to the same quality standard as their OEM products.
Can I use this magazine for competition shooting?
Yes. This 17-round magazine works well for USPSA, 3-Gun, and other competitive shooting formats where magazine capacity and reliability matter. The smooth feeding and durable construction hold up to repeated use.
Does this magazine come with a witness pad or extension?
No, this magazine comes as-is with a standard polymer base plate designed to sit flush with your pistol frame. If you want extended base pads or witness-style indicators, those are sold separately.
