The biggest barrier to 2011 ownership was never the gun — it was the magazines. Expensive, proprietary, and finicky. In 2026 that's splitting into two ecosystems: the Legacy STI/2011 pattern and a new Glock/SIG pattern. Here's what runs with what, and what it means when you buy or build.
The original 2011 magazine was designed by STI to feed .38 Super in competition. It's a double-column metal tube that has to taper into a single-column feed geometry to work with 1911 slide mechanics. That's hard to manufacture consistently.
The result: premium 2011 magazines run roughly $100–$130 each, and the metal feed lips deform if you drop a mag on concrete or gravel during a fast reload. Many shooters tune and measure their mags with calipers to keep them reliable. For thirty years, buying a 2011 meant buying into that headache.
Makers are now adopting Glock and SIG P320 magazine patterns — cheap, ubiquitous, and abuse-tolerant. The market is splitting into Legacy and Modern Logistics camps, and buyers are rightly confused about which mags work with which gun.
The 2011 market now runs on two magazine patterns. Which one your gun uses changes cost, durability, and where you buy spares. Here's how each shakes out.
This is the classic 2011 magazine — the STI/SV pattern that defined the platform. It's proven, widely supported by competition gear, and what most established custom 2011s are built around.
The tradeoffs are the ones above: higher cost per mag, sensitivity to feed-lip damage, and periodic tuning. For a dedicated competition gun that lives in a case and gets babied, none of that is a dealbreaker. For high-volume training or hard use, it's a real cost.
The newer wave of 2011s natively runs Glock G17 or SIG P320 magazines. Makers like Staccato, Oracle Arms, and Stealth Arms have moved this direction, and Kimber's 2K11 runs a Staccato-pattern mag that's shared across much of the broader ecosystem.
The appeal is obvious: Glock-pattern mags are everywhere, cost a fraction of a Legacy 2011 mag, and shrug off drops. The tradeoff is that you're tied to that pattern's geometry and capacity, and you give up some of the Legacy ecosystem's competition-specific options.
No. They are two different magazine patterns and the gun is built around one or the other. A 2011 cut for Glock-pattern mags will not run STI/2011 mags, and vice versa. That's why you decide the ecosystem before you decide the gun — it's a design choice baked into the frame, not an accessory you swap later.
Pick the ecosystem before you pick the gun. The magazine decision is a real part of the total cost — and it's the part most buyers overlook.
If you shoot a lot, train hard, or just don't want to babysit magazines, a common, drop-tolerant pattern saves real money and headaches. Cheap spares and minimal tuning add up fast over a high round count.
For a dedicated competition piece built around proven gear, Legacy still has the deepest match-specific support. If the gun lives in a case and gets babied between matches, the higher per-mag cost and periodic tuning are easy to live with.
Count magazines into the price of the gun. At $100–$130 each for Legacy mags, a handful of spares is a meaningful line item — over the life of the gun it adds up. The thing most buyers forget is exactly the thing that drives long-term cost.
LPWS builds run Atlas premium 2011 magazines. They're fit and function-checked as part of the build, not thrown in a box — the same standard we hold every other component to. When your gun ships, the mags that come with it have already run.
If you have questions about magazine pattern, capacity, or what your specific build will take, ask before you order. A hand-built gun should never leave you guessing about something as basic as which magazine to buy. The IslandBoy 11.0 ships ready to run, mags included.
