Type: BB blowback air pistol. 
Manufacturer: Umarex.
Materials: Mostly metal with a few plastic parts.
Weight: 1.5 pounds.
Barrel: 3.6 inches, metal non-rifled.
Propulsion: CO2 x 1.
Action: Semi auto, single action only.
Ammunition Type: 4.5mm steel BB's.
Ammunition Capacity: 17 round full size drop out magazine.
FPS: 360.

Trigger Pull: The trigger pull on the Umarex Beretta Mod. 84 FS is fairly long but in term of resistance is about a medium pull, there is no double action so single action only but the pull is longer than most single action triggers to accommodate the BB chamber mechanism on the magazine. Basically a BB is pushed into the breach/barrel during the first half of the trigger pull, then the trigger is released. I did notice a fair bit of friction during teh BB loading stage and it has been recommended to lubricate this area of the magazine to smooth out the trigger pull.

Accuracy: I tested the Umarex Beretta Mod. 84 FS from 30 feet back shooting at a paper target using a semi rested position (sand bag up front and standing in the back). My 10 shot grouping was just a bit above the center bulls eye and very well centered left and right All 10 BB's stayed within 1.5 inches with most of them grouping closer to a 1 inch group. The Umarex Beretta Mod. 84 FS also got a respectable 363 fps on this not super warm day so I would expect it to hit significantly higher than the claimed 360 fps during hot summer weather.

Build Quality: Being a pretty much all metal gun, makes the Umarex Beretta Mod. 84 FS feel solid and sturdy. The only plastic parts on the Umarex 84 FS where the grips and some magazine parts like the CO2 tab. The painted finish is a nice satin black. The fit and finish on this Umarex CO2 Blowback BB pistol is top notch with virtually no slide slop at all.

Realism: The Umarex Beretta Mod. 84 FS is a fully licensed replica of the real steel Beretta Model 84 FS. It is an extremely close copy in both looks and feel, has a nice snappy blowback action and field strips just like a real Beretta 84 FS. You'll also find a full size drop out magazine that holds the CO2 and BB's and a working slide catch/release that locks back when the magazine is empty.

Pros:

  • Good price for what you get!

  • Decent accuracy, power and CO2 usage combo.

  • Nice replica of the original Beretta 84 FS (Cheetah).

  • Crisp blowback action.

  • Working slide catch and release (Locks back after last shot).

  • Realistic working ambidextrous metal safety.

  • Full size dropout magazine that holds BB's and CO2.

  • Can be field stripped like original Beretta 84 FS.

  • Fully Beretta licensed.

  • Recessed barrel for realism. 

Cons:

  • Has the exposed CO2 tab on the bottom of the magazine.

  • Trigger is a bit long and tight because of how BB's are chambered.

Comments:

Umarex really came through on this one, perhaps they are listening to their customers more and more because time and time again we ask for the same things over and over again with our Replica Airguns: Metal parts where metal would be found on the real steel version, blowback operation for that realistic kick and single action trigger ability, a full size drop out magazine that holds the BB's and CO2, ability to field strip again like the original version, a recessed barrel so it does not look like a toy gun or a better way of saying it... make it just like the real steel version but have it shoot BB's :) I think Umarex got most everything covered with their new Umarex Beretta Mod. 84 FS CO2 Blowback BB Pistol.

Great replica but kind of a pain to shoot

The replica is wonderful -- it looks great, feels great, and the fit and finish are beautiful. Has a nice mass, a loud discharge, and it's very gas efficient. My only complaint, and it's kind of a big one because it really impacts the experience, is that the BB loading mechanism can make the trigger pull very sticky as the trigger pushes a BB out of the magazine. This same process is what gives it such a good gas seal, though, so that's the trade off. The spring pressure of the mag pushes the BB out of alignment a little with the breach and your trigger pull is forcing it past that obstacle. When it works it's nice -- you can take up the loading stage and rest right on the firing point for a nice crisp shot. When it doesn't work it's a chore and if you pull too hard you'll follow right through and shoot before you're well aligned with the target. The trigger reset is also a little finicky. Between the look and the price it's worth having but there are much more pleasant guns to shoot.

Great replica

I am very pleased with my purchase of the Umarex Beretta, it checks all the boxes. Very well-made fits well in the hand and just heavy enough. It is full blowback. Accurate and with a full magazine release. CO2 is easy to load. And all-around great gun except for one thing. I noticed after with my first CO2 that the notch in the cut out for the slide catch was beginning to bend. A web search shows that this can be a problem with this model. Ultimately the notch would wear out and The lock back after the last shot would fail. I mentioned this to Ryan at replicator Air guns and he immediately offered to exchange for another pistol. It is a pleasure dealing with this company.

Pleasantly Suprised

I was extremely impressed with this pistol, from the feel in hand, the way it shoots and the co2 efficiency. This gun feels really good in the hands, although I bought it for my girlfriend I enjoy shooting it just as much. The blowback is very snappy and quite impressive for such a small gun, almost sounds like a fire cracker on every shot. The accuracy is really good for a bb gun, I was hitting can sized targets from 50+ feet away with just a slight adjustment in my aim for elevation. On a nice warm day I got around 6-7 mags out a 12g co2 as well, very impressive considering the amount of blowback. The way the magazine is setup it is very easy to load more then one bb into the chamber if you are not careful but easy to avoid with practice. I did have one issue with this gun, the slide tends to lock back randomly instead of on the last shot like it should. Replica Airguns responded very quick and offered to replace it for me if I sent it back, but being on the opposite side of Canada during a pandemic it wasn't worth the wait to get the gun again, the problem is very minimal and doesn't affect the amount of fun we have with it! Thinking about ordering a second magazine to see if that changes it.

Beretta Cheetah

Very nice pistol, good blowback and very comfortable in the hand. Better carry gun than PPK I would advise you get the spare magazine also.

Great replica....but be forewarned if you have larger hands!

Beretta is one of my favourite brands and I have a preference for compact pistols, so the Beretta Mod 84FS was a no brainer for me. It is an accurate replica, easy to hold. Blowback is crisp. CO2 usage is excellent. However, I have smallish hands so this Beretta works for me...with a caution. The magazine release is VERY touchy and easy to engage accidentally resulting in misfires. Not sure if this is a defect in my pistol or a design flaw as I have not seen this specific problem identified by other reviewers. If you have larger hands it could be a problem for you. I like the pistol so much I learned to compensate with my grip which was actually kind of a good thing! May not be a good thing for you though. I like the lack of white warning instructions (they are black and recessed into the slide). The fact that Umarex used the CO2 tab design which extends below the magazine is a design weakness in my option. It would have been preferable if they would have used the allen key design to puncture the CO2 canister. Now, the trigger release clearly takes some getting used to, however, if you are patient and learn the release point, rapid accurate fire is very easy. So, I love a lot about the Beretta M84FS, so much so that the problems and / or design flaws I have identified do not prevent me from recommending the pistol, with cautions!

Has Issues

Had a lot of fun with this gun and kept it clean and maintained. Sights were slightly off and there's no adjustment, but easy enough to adapt. Averaged 70-80 shots per CO2. Easy disassembly/reassembly. Here's the main issue: Before burning through my first 6000bb container, the slide release latch started bouncing into my trigger finger when firing - like, hard. Took it apart and found the lock assembly had stripped and every time the slide hit the retainer, it tripped the lock. I still like the gun and it's cheap enough that I'm actually going to buy another, just to see if I got a factory defect the first time.

Finally, a field test video for you and I thought I would start off with the new Umarex Beretta Mod. 84 FS CO2 Blowback 4.5mm BB Pistol. This replica BB pistol is fully licensed and is a very decent operational replica to boot. It has a full size drop out metal magazine with blowback operation, a working slide catch/release and safety along with the ability to be easily field striped. Did I mention it's pretty much an all metal gun?
