Description
ETS, or Elite Tactical Systems Group, has built their reputation around translucent polymer magazines, and this Carbon Smoke 17-rounder for the full-size Sig Sauer P320 is a good example of what they do. The smoky semi-transparent body lets you see your round count and ammo type at a glance, which comes in handy during drills or competition when you need to know exactly what is in the gun without pulling the magazine.
The polymer construction is rated for extreme impact resistance, along with solid resistance to harsh chemicals, UV exposure, and temperature extremes. The feed lips are designed to be creep-resistant, meaning they should hold their shape even when the magazine sits loaded for extended periods. A non-tilt follower helps keep rounds positioned correctly on their way up, and the ergonomically shaped floor plate makes it easy to grip and seat the mag quickly from a pouch.
One feature worth calling out is the base plate compatibility. The ETS P320 mags use a Glock-style base plate, which means they are interchangeable with the broader ETS lineup of 9mm double-stack magazines and also open up a wide range of aftermarket Glock-compatible base pad extensions if you want to experiment with grip or capacity options.
This magazine fits the full-size Sig Sauer P320 in 9mm and is best suited for range use, training, and practice drills where you want affordable extra mags without breaking the bank. ETS backs their products with a lifetime warranty, which is reassuring at this price point. Each package includes one magazine.

Frequently Asked Questions
Will this ETS magazine work with the P320 Compact or Subcompact?
This specific model is sized for the full-size Sig Sauer P320 and will flush-fit that frame. It may fit and function in a compact or subcompact P320 grip module but will protrude from the bottom. Always verify fit with your specific grip module before relying on it.
Can I use aftermarket base pads or extensions with this magazine?
Yes. ETS designed the P320 Carbon Smoke magazines with a Glock-style base plate, which makes them compatible with the wide range of Glock-compatible aftermarket base pad extensions on the market. The base plates are also interchangeable across the ETS line of 9mm double-stack magazines.
How does the carbon smoke finish differ from the standard clear ETS P320 magazine?
The Carbon Smoke version has a darker, semi-opaque tint compared to the fully clear translucent model. You still get the round-count visibility that makes ETS mags popular, but with a slightly stealthier look. Functionally, both versions share the same design and specs.
Is this magazine a good choice for everyday carry or just range use?
Most people reach for OEM Sig metal magazines for duty and carry use, where reliability margins matter most. This ETS mag is a great value pick for range days, training, and keeping spare mags on hand without spending a lot. It is backed by a lifetime warranty, which adds some peace of mind.
Does the ETS P320 magazine work with Glock magazine loaders?
The Glock-compatible base plate design means many Glock-style magazine accessories and loaders will work with this magazine. ETS also produces their own magazine loaders that are compatible across their 9mm double-stack lineup.
