So... I decided to give it a try. I bought 4 of these wondrous little pea shooters. 
Running a State Licensed Nuisance/Pesting business, I'm always looking out for an effective yet inexpensive way to work my contracts. Prior to this purchase, I did enjoy the use of my Brocock, Kral, and nostalgic Sheridan .20 cals. (Only pumping to 5-6 to get the reach I needed for birds and rodents in dairy barns, calf pens, and grain/feed stores. They worked, and there's no denying the accuracy of a Blue Streak or a Sheridan H pistol at 10-30 yds. But if a quick follow up was needed... Well, you know the routine.)
In steps this new little wonder. The Umarex Notos. What a fantastic carbine/pistol.
It's easy to handle, light weight, and pretty balanced. Out of the box, My trigger was 3.1 pounds (average out of 7 shots). Really not to shabby. It is surprisingly smooth. Not a super nice trigger like an FX Impact M3, AGT Vulcan 3, Kalibrgun. But smooth for its price point.
They came nicely packed. Decent presentation. Cardboard outer box, foam cutout insert holding the airgun and included accessories nicely.
Open the box, the receiver, barrel, rail, and fixed moderator are in one clear plastic sleeve/bag packed in its own cutout. And the grip/stock in another. There is a separate small zip lock bag with 4, 2.5mm(?) Allen screws to attach said grip/stock. Followed by another zip lock bag containing 1, (Yes only 1.
) 7-shot mag and fill probe.
I'll be frank, I don't care for the tiny, quarter sized diameter 7 shot mags. The clear cover is kind of sloppy fitting. Yes, there is a small set screw that can be adjusted bringing the tiny detent outward to help with the slop. But, it causes misalignment when feeding the mag into the receiver if adjusted incorrectly. I'm thinking I may try a tiny o-ring under the face plate provided the friction doesn't hinder the mag spring and rotation. That's all trivial I suppose. Main thing, they work.
With everything assembled, I ran a few cleaning patches through the barrel with Balistol. It only took 4 passes. Not really to bad.
I filled er up to 2000 psi, (The gauge reads in single digits x 1000.) and waited a few for signs of leakage. After 20 mins, I topped it off to 3625 psi (250 Bar) The gauge has 3 colors. Yellow, Green, and Red. Filling to the edge of Green/Red is 3625 psi (250 Bar)
I mounted a March Optics 3x28 micro scope on top as I'm only planning on 10-20yrd engagements within the confines of barns and out buildings. This March Optics 3x28 has a medium width etched glass crosshairs with hash and mil dots. It's a simple, not too busy reticle perfect for pesting up close. It's also red/green illuminated. Just under 5" in length, was the perfect hood ornament for what I intend to use it for. (60 bucks shipped Aliexpress)
As seen in other posts/videos, this little Notos .22 stacks shot on shot. I zeroed using simple Crosman 14g Hollow Points. The Pro Chrony says 728 fps average.
At its current factory setting, after 21 shots, I still have 2100 psi in the tube.
I did try some NSA .216 20.2g slugs and managed to get the same grouping and... even got a satisfying pop when targeting an English Sparrow 20yds out.
Final thoughts, If my understanding is correct, Carm makes a 12rd mag that fits the Artemis PP750. I'll be ordering a few of those. Honestly, I can see me fumbling for the factory micro mag and dropping it in an unpleasant area near the cattle or sheep pens.
The cocking lever is smooth. Slightly gritty towards full cock. My oversized meat grabbers don't really have an issue with the handle. Though, if wearing gloves, there will be an issue. So, I'm going to head down to the machine shop and dive into my creative side to correct this.
I did order from Pyramid Air, 2 extra mags, the pistol sights, and grip scales. Mags run $19.99 (USD) each. The fiber optic open sights, (nicely made) were $12.99 USD, and the Grip scales/plates were $9.99 USD. That's not too shabby if you wanted a dedicated pistol.
This one has potential! As I stated, I bought 4. 3 for my guys and I to use on site and 1 for me to go mad scientist on.
Hope this one helped at least one of ya's out there. So far, first impressions say it's worth the 230 bucks.
Cheers,
