A few months ago, we took a look at the CZ Scorpion EVO 3 S2 Pistol Micro w/ Folding Brace and loved it! Today, we look at its slightly large counterpart, the CZ Scorpion

EVO 3 S1 Pistol.

The CZ Scorpion EVO 3 S1 Pistol is a mostly polymer 9mm pistol caliber carbine made by CZ. We take a look at the ergonomics and function of this fun compact carbine

CZ’s design ethos revolves around having the fewest parts do the most work since fewer parts mean fewer problems.

The top of the gun is crested by an 11” long Picatinny accessory rail upon which are attached the front and rear sights. Both front and rear sights have black metal trapezoidal pyramid bases and serrated downward rear slopes. The front sight is a post sight. The rear sight is fully adjustable. It has four different sight selections that one cycles through manually to pick the optimal aperture.

The gun has a very unusual tumblehome design handguard. It’s not an M-LOK type, but it’s quite interesting. The handguard’s bottom juts out not as far as the nose of the flash suppressor, but to about the thread. It rises back at a gentle angle and then just above the barrel slopes back rakishly to the front sight and top rail.

CZ Scorpion EVO 3 S1

There’s a medium-length Picatinny accessory rail along the bottom fronted by a black triangular hand stop and another medium length Picatinny rail on either side. As an aside, all four Picatinny rails are missing their center of each tie forming a canyon of sorts along each rail. This is important since it shows how committed CZ is to shaving any unnecessary weight.

The gun’s cold hammer-forged barrel is 7.72” long, which is short and compact. At 16.5”, the overall length is also compact though the height is 9.4”. Weight is only 5.0 pounds!

The CZ Scorpion ends with both an 18×1 and a 1/2”x28 TPI threaded muzzle that comes standard with a slotted flash suppressor.

The gun features ambidextrous controls (e.g. trigger safety and magazine release) and a swappable charging handle for left-hand or right-hand use. The mag release looks like an inverted trigger that sits on the front of the trigger guard. Just tilt it forward to release the magazine.

The frame, grip, and magazine are all polymers. The grip is interesting: it’s relatively tall and thin. It has long vertical serrations at the front and back but smooth sides. And it’s flared at the bottom as is the mag well.

Firing is via a mechanical single-action trigger.

This firearm comes with either a high capacity 20 round curved box polymer magazine or a lower capacity 10 round magazine. Fascinatingly, the magazine flanks are translucent, so one can see the rounds inside (or just the spring) as the magazine empties.

The EVO 3 platform has been designed with accessorizing in mind and it has a range of forends, magazines, braces, grips, and more available to it.

CZ is a company that is clearly focused on innovating and making some fun firearms.

The CZ Scorpion EVO 3 S1 pistol, at first glance, is a fascinating gun that is almost entirely polymer.

It doesn’t appear to be very durable on the outside, but it does look very aesthetically pleasing. The EVO is a small, compact pistol caliber carbine chambered to 9mm.

The gun features a top Picatinny rail and three Picatinny rails on the front at the handguard’s three, six, and nine o’clock positions. It is relatively ambidextrous, at least with the safety. We’ll talk more about that later on.

The CZ Scorpion EVO 3 S1 pistol comes with metal iron sights attached to the top rail of the gun. This particular model has a folding SB Tactical brace.

CZ Scorpion Ergonomics

The grip ergonomics of the CZ Scorpion EVO 3 S1 pistol are somewhat iffy, mostly revolving around the pistol grip.

Aside from the grip, the front of the gun, holding it in a C Clamp configuration, feels great.

To me, it does feel better to hold it at the magazine well, which is typically a pretty big no-no, especially when you’re shooting ARs.

Holding the Scorpion EVO 3 S1 in the C-Clamp style grip does seem to feel really good.

The EVO 3 S1 does come with a black hand stop. Mine is the gray model, but there’s an all-black model as well.

I actually use it as a hand stop in the forward position. So I don’t slide my hand too far towards the end of the gun.

I usually run this gun suppressed, so I don’t want to bump my suppressor accidentally. I usually slide my hand all the way to the front and use the hand stop basically as a stop in the forward position instead of in the pullback position.


The safety of the Scorpion is probably, other than the grip, the most contentious or disliked thing on the firearm.

CZ Scorpion Evo 3 S1 Safety
Buy CZ Scorpion EVO 3 S1

The issue with the safety is, is when the gun is in the fire position.

On the right-hand side of the gun, typically for right-handed shooters, it’s going to poke into your trigger finger.

Even when the trigger finger is on the trigger itself, you’re still going to be getting hit by the safety.

HB Industries makes a safety delete button, and the safety delete removes the lever on the right-hand side, effectively making this not an ambidextrous safety.

Scorpion Safety Delete
Buy CZ Scorpion EVO 3 S1

However, based on where the safety is placed, you really don’t mind losing the ambidextrous safety to have a more comfortable shooting experience.

HB Industries also makes an AK-style selector, as well as a few other options.

Personally, I picked up the CZ Scorpion grip by YetiWurks because I liked the design, and they also color-matched it to the same gray as this particular Scorpion EVO 3 S1.

Pistol Grip

The grip is at an almost 60-degree angle, and that 60-degree angle is a very non-fluid angle for holding firearms.

Most people say the first thing they change out on their Scorpion is either the safety selector I mentioned above and the grip.

There are plenty of aftermarket grips, and on this particular CZ Scorpion EVO 3 S1, I’ve recently changed out the grip to the Yetiwurks.

You can see a picture of the stock grip below and the new grip.

You can clearly see the different angles that exist. That angle is just not conducive to a human hand and how they typically grip firearms.

Magazine Release

Many people don’t like the stock magazine release because it’s built into the frame.

When you use this magazine release, it’s actually quite easy.

Just take your finger, push it forward, and it’ll drop the magazine free. It’s that simple.

The one thing that everybody complains about is that it’s not very protruded, and it can sometimes be hard to hit.

So a lot of people will purchase again from HB Industries, a paddle-style magazine release.

Personally, I have no issues with the magazine release, so I’ll probably leave my stock and not switch to the pro stock or the duckbill style magazine release. Although, they are great options if you have an issue with this magazine release.

Magazine Well

The magazine well has a flared or chamfered design, just like the CZ Scorpion Micro that we reviewed previously.

They have the same exact magazine well configuration.

I don’t have any heartburn with these magazine well designs.

Bolt Release/Bolt Hold Open

The bolt release/bolt hold open is located on the left-hand side of the firearm.

bolt release
Buy CZ Scorpion EVO 3 S1

It is a paddle-style design and slips down right smack dab in the middle of the gun.

It sits just in front of the safety and just to the upper left of the trigger. It also sits directly on top of the magazine release.

I find the bolt release/bolt hold open not very useful because it has an MP5 style charging handle.

I won’t use the bolt hold open to hold the bolt open very often, and I would slide the charging handle into the up position.

But there is a use for the bolt hold open in that it provides for the last round bolt hold open.

Charging Handle

The charging handle on the CZ is actually quite nice.

cz mp5 charginghandle
Buy CZ Scorpion EVO 3 S1

It’s modeled after an MP5 style charging handle, and it’s located at the front of the gun, where you can reach up and grab it with your left index finger and pull backward.

It also has a locking position to hold the bolt all the way open.

charging handle
Buy CZ Scorpion EVO 3 S1

So you grab the charging handle, rack it all the way to the rear, slide it upwards, and it will hold the bolt in an upward position.

Now, I have noticed that it doesn’t have a seated position like an MP5, and you can easily hit it accidentally, and it’ll slide forward.

It does work well and holds the bolt open, but know that you could potentially bump it, and it’ll slide the bolt forward and release the charging handle from the lock position.

The handle itself is a U-shaped plastic polymer.

Personally, I don’t have any issues with it, but there are metal replacements for it if you would like to change it out to a sturdier charging handle.

Scorpion Magazines

There are a handful of different aftermarket magazines, not just CZ magazines.

cz magazine

Magpul makes quite a few, and it is an excellent design as far as I’m concerned, and these are the same pattern magazine as the PSA AK-V.


The CZ Scorpion EVO 3 S1 pistol comes as just that: a pistol.

You can add an SB Tactical brace, and some may sell you a combination package with an SB Tactical brace.

It’s configured by default with their CZ standard muzzle adapter, as well as an end cap for your rear brace attachment that covers the Picatinny rail.

Optics Mounting

Like most guns, the CZ Scorpion contains a 1913 Picatinny rail on the top of the gun that will allow you to mount pretty much any Picatinny mounted optic.

CZ Scorpion EVO 3 S1
Buy CZ Scorpion EVO 3 S1

Preferably on this gun would be something like a red dot sight.

The Scorpion is chambered in 9mm and a pistol caliber carbine, which would not make a good candidate for a low variable power optic.

Personally, I’m putting on the Holosun HS403B optic for this Scorpion.

Accessory Mounting

Accessories on this gun are aplenty.

If you go to any aftermarket website for parts, you will likely find something for the CZ Scorpion.

The Scorpion allows you to mount on the Picatinny rails on the front handguard anything from light switch mounts, to hand stops, to foregrips, to you name it. You can mount it on the Scorpion 1913 Picatinny handguards.

I mounted the Cloud Defensive CLS and the Streamlight Protac Light.

Additionally, you can mount an optic or a flashlight on the top of the 1913 handguard, like the Cloud Defensive OWL light.

Light Options

The light options on this gun are endless.

Personally, I decided to run the Streamlight Protac mounted to the three o’clock position.

Buy CZ Scorpion EVO 3 S1

I have the tape switch with the Cloud Defensive mount attaching the tape switch on the opposite side at the nine o’clock position.


The sling on this gun has some unique options that a lot of guns don’t come with.

There are two points of sling attachment on the left side of the gun. One is in the middle, to which you could attach a clip or a key ring. Then one on the very back of the gun before you get to the brace attachment area.

It’s just a circular attachment that you could also attach a key ring to or a clip. If you’re like me and have the SB Tactical brace, you could also attach it to the SB Tactical brace in one of many locations. On the right side of the gun, there are mirrored sling attachment options for this gun.

Trigger Pull

The Scorpion has arguably the worst trigger I’ve ever felt in my life.

That is the one big major drawback of the Scorpion. Good thing there are aftermarket options for the trigger, but from the factory, it is not a good trigger in the slightest.

The trigger does have a take-up.

However, it is an extremely strong take-up with no real wall.

Squeezing trigger all the way to the rear, you are going to be surprised by it because again, there’s no wall, and there’s really not a definitive crisp break.

It’s very hard to tell where the break is.

The reset is very defined. It’s not terrible, but then there’s still take-up back to the wall if you even want to call it a wall at this point.

Ergonomics of the Gun Overall

The gun actually feels great in your hand.

It feels great holding it, and it feels just overall solid.

Now, granted, it is made of a polymer, but it does have a nice feel. It’s not heavy. It’s not excessively light.

It just kind of falls right in the middle of where you’d want this gun to fall weight-wise because you’re going to have to manage recoil on this super light gun, and of course, it is a 9mm pistol caliber carbine.

The grip does take getting used to, especially if you don’t replace it with a 45-degree angle grip versus the 60-degree angle grip they come stock with.

If you don’t change that out, it’s not quite as comfortable. It’s not unbearable, but it’s definitely something that takes some getting used to, and it’s not something you’re going to want to shoot regularly excessively.

The SB Tactical brace is extremely fluid with this gun and really completes the gun overall.

It’s slightly more than just a range toy, but I wouldn’t say it’s a workhorse. If they came out with a metal body CZ Scorpion EVO 3, then I think we might have a contender for a very serious workhorse weapon that could be home defense, even have military applications.
