Comments: Umarex set a new standard for realism with this BB pistol replica. The construction of this gun is metal anywhere metal would be found on the real M84. The blowback operation provides realistic kick and single action trigger ability. A full size drop out magazine holds ammo and CO2. They even included field stripping capability and a recessed barrel. The only discernible differences between this airgun and the real steel version are the BBs in place of bullets.

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.

Good value

This is one of Umarex's better recent pistols and very good value especially at Michaels price. At the time of writing it's $30.00 cheaper than Cabelas. The pistol is very nicely made and fits the hand well. Action and accuracy is very good for a relatively short barrel. It uses the same kind of blowback system and magazine as the Makarov Ultra so is very snappy and quite loud. Even though magazines are expensive the trend towards the CO2 cylinder in the magazine is a good one as the seals there can be a point of failure.Very fast processing and shipping from Replicaairguns as usual.

Type: BB blowback air pistol.
Manufacturer: Umarex.
Model: Beretta Mod. 84 FS. (Cheetah)
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.

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.
