Smith & Wesson CSX E-Series: Micro 9mm Redesign Review
Description
The Smith & Wesson CSX E-Series is here, and it’s fixing nearly everything shooters didn’t love about the original CSX. ⚡ From a crisp new trigger to modular grip options and full optics readiness, this little single-action 9mm packs a ton of performance into a micro-compact frame — and it does it at a price that won’t empty your wallet.
✨ What you’ll learn in this episode:
🔭 Optics Ready Improvements
RMSc footprint for popular optics like Holosun 407k/507k
Innovative “Clear Sight Cut” keeps gases from fogging your optic 👓
Rear sight is removed with the optics cut, but some optics allow for front sight co-witnessing
🎯 Trigger Overhaul
Brand-new, clean 4 lb. break with a crisp, short, audible reset 🔥
A huge leap forward from the mushy, quiet trigger of the original CSX
Shooters agree: “it doesn’t suck anymore”
🤲 Modular Grip System
Swap from deep concealment micro to compact/full-size grip feel
Interchangeable backstraps & palm swells for a custom fit
Improved texture wrapping around the entire front strap for more control
📏 Size, Capacity, and Options
Two barrel lengths: 3.1" and 3.6" for concealment or sight radius preference
Three included magazines: 12-round flush fit, 15-round, and 17-round 🔄
Extended grip modules let longer mags fit flush, effectively turning it into a mid/full-size pistol
⚡ Performance & Reliability
Shoots flat, manageable recoil, and surprisingly accurate (1” groups at 7 yards 👀)
250+ rounds tested across multiple ammo brands with no failures
Easy-to-rack slide, great for smaller hands or older shooters
⚠️ Considerations
No accessory rail for lights/lasers
Rear sight removed with optics cut — no traditional co-witness
Some larger-handed shooters report slide or safety bite
Single-action only, which may not appeal to striker-fired fans
💰 Price & Value
MSRP ~$699, often found closer to $600 💵
Comes with three mags, multiple grip options, and optics readiness out of the box
Competitor comparison: Staccato CS does something similar… for $2,500 🤯
💡 Bottom Line: The CSX E-Series shows Smith & Wesson listened to customer feedback and delivered big improvements. It’s a versatile, affordable micro-compact that shoots like a bigger gun. If you want single-action performance in a concealed carry pistol without the $2,500 price tag, the CSX E-Series deserves a serious look.
