Let’s talk about the CROSS STX. This isn’t a review from a spec sheet; it’s from handling this specific model, inspecting it before it ships, and listening to the feedback from folks who’ve bought it from us. In a market flooded with polymer-framed striker-fired pistols, the STX stands out for its blend of precision engineering and practical reliability. It’s a tool, first and foremost, and one we’ve found performs consistently.

Stand-Out Features
The first thing you notice when you unbox an STX from us is the finish. We inspect every product before shipping, and the STX consistently passes our visual QC. The machining is clean, the nitride finish is even, and the slide-to-frame fit is correct to spec—no slop. It feels solid, not toy-like. The ergonomics are a strong point; the grip texture is aggressive enough for a secure hold during a range session but won’t shred your shirt for concealed carry. The optic-ready system is straightforward, using common mounting patterns, which is a relief compared to some proprietary nightmares we’ve seen.
Reliability is where this pistol earns its keep. In our testing, it feeds reliably with both brass and steel case ammunition. We don’t just cycle a few rounds; we run boxes through it. This isn’t a safe queen. It’s designed to go bang every time, and in our experience, it does. Our customers report the same, with a satisfaction rating of 4.7 out of 5 across their purchases. That tells you more than any marketing claim.

Strengths and Weaknesses
✅ Pros:
- Proven Reliability: As noted, it feeds reliably with both brass and steel case ammunition in our testing. This is a workhorse.
- Superior Out-of-Box Trigger: The trigger break is clean and consistent, better than most factory striker triggers we handle.
- Excellent Ergonomics: The grip angle and texture make for a natural, secure point of aim.
- Robust Build Quality: Clean machining and proper fit. It passes our pre-ship inspection every time.
- Practical Optic Ready System: Uses common footprints—no hunting for obscure, expensive adapter plates.
❌ Cons:
- Price: It sits at a premium price point. You’re paying for the refinement and features.
- Aftermarket Support: Holster and accessory options aren’t as vast as for the most ubiquitous brands… yet.
- Magazine Cost: Proprietary magazines can be more expensive than some industry-standard options.
Best For
Buy it if: You want a refined, reliable striker-fired pistol for duty, home defense, or competition that works right out of the box. You appreciate good ergonomics and a quality trigger without needing immediate aftermarket upgrades. You plan to mount an optic and want a simple, direct system.
Skip it if: Your budget is strictly under a certain threshold and you prioritize absolute lowest cost. You need immediate, unlimited holster compatibility with every maker on the market. You prefer the absolute lightest possible trigger pull for competition above all else.
Your Questions Answered
Is the CROSS STX reliable for concealed carry?
Based on our testing and customer feedback, yes. Its reliability with various ammo types and its consistent performance make it a viable option for carry. Always train extensively with your chosen firearm and ammunition.
What optics fit the STX slide?
The optic-ready system uses a plate system that accommodates footprints like Trijicon RMR/Holosun 507C, Leupold DeltaPoint Pro, and Shield RMS. The correct plate is included.
How does it compare to a Glock 19?
It’s a different philosophy. The STX often has a better out-of-box trigger and ergonomics for many shooters. The Glock has unparalleled aftermarket and holster support. Both are reliable. It comes down to preference and what you value more.
Is it California compliant?
No, the CROSS STX is not on the California Roster of Handguns Certified for Sale and is not compliant for sale by a California FFL to a non-exempt resident.
Where can I buy CROSS online?
You can purchase the CROSS STX right here at Polymer80Warehouse. We ship from our Cape Girardeau warehouse. Our low return rate on this model indicates customers are generally satisfied with what they receive.
What’s the real-world weight?
We measured it on our bench scale at 4.3 ounces, unloaded. This aligns with the manufacturer’s spec and contributes to a good balance between controllability and carry comfort.
Does it come with a case and accessories?
Yes, it includes a hard plastic case, one 17-round magazine, the optic mounting plates and hardware, a cable lock, and the owner’s manual.
