Forty rounds of 9mm in a P320 is a hard thing to argue with, especially when the magazine holding all of it is this well built. ETS makes these from an advanced impact-resistant polymer that can handle being dropped, thrown in a range bag, left in a hot car, or exposed to cleaning chemicals without cracking or going brittle. The clear body isn't just a gimmick either. Being able to glance down and instantly know how many rounds are left, or confirm what ammo type is loaded, is genuinely useful whether you're running drills or doing a quick check at the end of a session.
One thing ETS got right that matters more than people realize is the feed lip design. The polymer is formulated to be creep-resistant, which means the lips and body hold their shape even when the mag is stored fully loaded for extended periods. Paired with a non-tilt follower, rounds feed consistently without the kind of nose-dive issues that plague cheaper high-capacity mags. The ergonomically shaped floorplate is also a nice touch since it's easy to get a grip on for a quick drop and reload.
This mag fits the full-size, compact, and subcompact P320 and P250 platforms in 9mm. The base plate is designed to be tool-free for disassembly, so cleaning and inspection are straightforward. Baseplates are also interchangeable with other ETS 9mm double-stack magazines, and the base is compatible with Glock-pattern extensions if you want to experiment. Made in the USA, lifetime warranty included.
Yes. This magazine is compatible with the P320 full-size, compact, and subcompact models, as well as the Sig P250 in those same configurations. Keep in mind that with a 40-round extended magazine, the grip stub on compact and subcompact frames will leave a significant portion of the mag extending below the grip, which is totally normal for a mag of this capacity.
ETS uses a purpose-built advanced polymer that's specifically designed to resist impact, UV exposure, heat, cold, and harsh chemicals. It won't crack or become brittle the way some cheaper polymer mags do over time. The translucent construction is part of the polymer formulation itself, not a coating, so it holds up the same as any other ETS magazine.
Yes. ETS specifically engineered the polymer and feed lip geometry to be creep-resistant, meaning the lips and body won't spread or deform under the constant pressure of being stored fully loaded. This is a common concern with high-capacity polymer mags, and it's one ETS addressed directly in the design.
Instead of relying on small witness holes cut into the side of the mag, the fully translucent body gives you an immediate, unobstructed view of your round count and the type of ammunition loaded. This is particularly handy at the range when rotating through different loads, or any time you want a quick visual status check without dropping the mag.
The baseplate is designed for tool-free removal, so you can break it down, clean it, and inspect the follower and spring without needing any special tools. The clear body also makes it easy to spot any debris or buildup inside before it becomes a problem.
ETS backs all of their magazines with a lifetime warranty. For a magazine in this price range, that's a strong commitment and reflects the confidence they have in the materials and manufacturing. It's also made in the USA.
