Stealth Arms Platypus Comp

Today we’re taking a look at the Stealth Arms Platypus Comp — a factory-new, compensated 9mm that blends classic 1911-style ergonomics with a very modern twist: it runs Glock magazines. Mine is the full-size 5-inch Government-length setup with an integral compensator, so you get the longer sight radius and full-size control, with comped behavior baked in from the factory instead of being an afterthought.

Quick disclaimer up front: this write-up is for informational and educational purposes only. Everything was handled safely in a controlled environment. This is simply my review and my perspective, and your preferences might be different than mine.

First, let’s talk about why the Platypus matters. There are plenty of 1911/2011-style guns that shoot flat and fast, but magazine compatibility is usually where the “practical” side of the conversation gets expensive. The Platypus flips that by using Glock mags, which are cheap, common, and available everywhere. That alone makes it easier to actually run the gun hard without turning every range day into a “don’t drop the mags” anxiety session.

Now, my exact configuration. This one is the compensated 9mm Platypus with the new variation prickle cut slide, SRO/RMR footprint optics cut, prickle grip texture, full-length dust cover with a rail, ambidextrous safety, and a curved skeleton trigger rated in the 3.0–3.5 pound range. It came in the Stealth Arms leather case with two 17-round Glock 17 magazines and the optics hardware. Mine also showed up with the polished barrel and a magwell already installed. Long term, I may swap the barrel to DLC for durability, because I’m rough on gear and I like finishes that hold up, but I’ll admit it — the polished barrel looks slick right out of the box.

The optic setup is another thing Stealth Arms did right. This is a direct optic cut, so you’re not stacking plates just to mount common optics. That lower mounting height makes dot presentation feel more natural and keeps your dot-to-iron relationship cleaner. It also helps with co-witnessing, because the optic isn’t riding a skyscraper above the slide.

Let’s talk grip texture, because this is a big one for me. I love the prickle grip texture. This is exactly the type of aggressive grip I prefer — the kind that stays planted when you start shooting faster, when your hands get sweaty, and when you’re moving the gun hard through transitions. If you’re someone who hates aggressive texture, you may not love it. But for my preferences, this is the right answer.

From a controls standpoint, the only thing I’d add is some kind of gas pedal. I like having a dedicated thumb ledge so I can really drive the gun. That said, it’s not a deal-breaker — you can adjust grip, use the light as a reference point, and keep it moving.

On the range, the Platypus Comp does what you want a compensated full-size 9mm to do. The integral comp and full-length dust cover work together to keep the gun flatter and make the dot track more predictably. Instead of a sharp snap, you get more of a controlled push, and the dot returns consistently. That’s what makes speed sustainable, not just possible for a couple strings.

Reliability is always the “yeah but…” moment with any new platform, especially when people start mixing comps, tight tolerances, and various ammo weights. In my experience, the gun ran boringly reliable. I put about 500 rounds through it without any malfunctions. Most of that was 115 grain, and I generally prefer 124 grain, but my logic is simple: if it’ll cycle the common 115 grain stuff without drama, 124 grain should be even less of an issue.

Accuracy was exactly what you’d expect from a full-size gun with a good trigger and a stable sight picture. At 10 yards, it stacked tight groups. But for me, the real value isn’t slow-fire bragging — it’s how easy it is to keep hits where they belong while shooting at speed and staying accountable. That’s where the comp, the weight, and the consistent trigger really show up.

Trigger-wise, the 3.0–3.5 pound curved skeleton trigger felt crisp and clean. The wall was consistent, the break was clean, and the reset was short enough to run the gun without guessing. I usually prefer a flat trigger and may change it out down the road, but even as-is, it’s absolutely in the “run it hard” category.

So here’s the bottom line. The Stealth Arms Platypus Comp is exactly what it’s supposed to be: a purpose-driven, shoot-flat, shoot-fast, modern 1911-style pistol that stays practical because it runs Glock magazines. I love the aggressive prickle texture, I like the direct-mount optic cut and how low it keeps the dot, and I like the overall “ready to run” feel with the magwell and full-size setup. I’d still like a gas pedal, but that’s a preference item, not a flaw.
