Warne +0 Magazine Extension for Sig Sauer P320 9mm Luger - Black
- Finish-Color:
- Black
The Warne +0 Magazine Extension for Sig Sauer P320 9mm Luger is purpose-built for shooters operating under 10-round magazine capacity restrictions. This zero-capacity extension maintains your standard magazine's round count while adding the ergonomic benefits of an extended grip—a smart choice for competitive shooters, legal compliance in restricted states, or anyone who simply wants a more comfortable purchase and draw from the holster. Machined from 6061 T6 aluminum billet and finished with Type 2 hardcoat anodize, it's built tough enough for regular range use and defensive carry.
The design prioritizes function over bulk. You get finger grooves that make it easy to strip the magazine from your P320 under stress, plus an ergonomic profile that improves how the mag seats in your hand during reloads. The extension is secured with a Torx head screw and washer, so it stays put through thousands of rounds. Built and designed in the USA, it reflects the kind of straightforward engineering that works when it matters.
Whether you're prepping for a local 3-gun match, complying with state law, or just want a better grip on your carry mag, this extension gives you a legitimate way to improve your P320's handling without pushing round capacity.
