US Palm Storm and EOS Series Make Landfall (.99
About this product
When US Palm announced they were moving from top-tier accessories into building complete firearms, a lot of folks, myself included, were curious. Could a company famous for the best AK grips on the market really build a serious rifle? After getting my hands on the first production models of the US Palm Storm CAT 4, the answer is a definitive yes. But the real headline for the practical shooter here in Iowa is the companion piece: the US Palm EOS pistol. Chambered in the formidable .99 caliber, this isn't a range toy. It's a purpose-built, duty-ready handgun that represents a serious new option for anyone looking for maximum terminal performance in a pistol platform. If you've been waiting for a next-generation sidearm that prioritizes rugged reliability and raw power without the bulk of a traditional large-frame pistol, the US Palm EOS has landed on our shelves.

Why We're Stocking This
At Iowa Gun Shop, we don't just order the latest hype. We bring in tools we believe in, that fill a gap for our customers. The US Palm EOS pistol does exactly that. We've handled the prototypes, and the fit and finish is exceptional—it feels like a handgun that's already been through a thousand-round class and come out smoother. US Palm's reputation for over-engineering their polymer products, like their legendary grips, translates directly to the EOS frame. It's rigid where it needs to be, ergonomic in the hand, and inspires immediate confidence. This isn't a company dipping a toe in the water; this is a full-scale launch with a product that stands up to the established names on the market, and we want our shooters to have access to it first.
Furthermore, the .99 caliber chambering is a major statement. It's a serious round for serious applications, and having a modern, ergonomic pistol built around it from the ground up is a game-changer. We stock plenty of .45s and 10mms, but the US Palm EOS offers a distinct ballistic profile that appeals to the knowledgeable shooter looking for something beyond the ordinary. We trust the build quality, and we believe in the mission behind the gun: no-nonsense, durable performance.
Who It's For
- The Ballistics-Conscious Shooter: Anyone who studies terminal performance and wants a modern pistol platform chambered for a potent, less-common caliber like the .99.
- The Duty/Carry Professional: Law enforcement, security personnel, or qualified citizens seeking a high-capacity, optics-ready sidearm built for hard use and extreme reliability.
- The Suppressor Enthusiast: With its threaded barrel and tall sights standard, the US Palm EOS is a natural host for the matching US Palm EOS series suppressor, designed as a unified system.
- The "Tool, Not a Jewelry" Owner: Shooters who value function over flash, and appreciate a firearm engineered for durability and simple maintenance above all else.
- The US Palm Platform Adopter: Those who already trust US Palm's CAT 4 Storm rifle and want a sidearm from the same ecosystem, with potential for shared manual of arms and accessory synergy.
Frequently Asked Questions
Q: Is the .99 caliber just a rebranded 10mm or .45?
A: No, it is its own distinct cartridge. While ballistics can be similar to the upper end of certain loadings, the .99 is a proprietary design from New US. Ammunition is currently produced by a select few manufacturers partnering with US Palm, and we are stocking compatible rounds. Always use ammunition specified for your firearm.
Q: How does the size of the US Palm EOS compare to a Glock 17 or similar full-size pistol?
A: The US Palm EOS has a comparable footprint to a modern full-size duty pistol, but the grip geometry is uniquely US Palm—it's exceptionally ergonomic and fills the hand securely. The weight is managed brilliantly, making it feel very pointable despite its robust construction. You need to handle one to appreciate the balance.
Q: Are magazines and holsters readily available for this new model?
A: US Palm is launching with ample magazine production, and we have them in stock. Holster support is growing rapidly from major Kydex manufacturers due to the standard rail and slide profile. We recommend checking with your preferred holster maker, but several common duty holster models are already confirmed to fit the US Palm EOS.
