Umarex Beretta M84FS CO2 BB Pistol

Description

Type: BB 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 BBs
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 the 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 BBs 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 were 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 terms of both looks and feel and 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 BBs 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 BBs 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 BBs are chambered.

Comments: Umarex really came through on this one; perhaps they are listening to their customers 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 BBs 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 BBs :) I think Umarex got most everything covered with their new Umarex Beretta Mod. 84 FS CO2 Blowback BB Pistol.

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.

Beretta 84FS

Really nice gun that eschews the usual 'stapler with a hand grip' design philosophy of most automatics, accurate reproduction of the original with well implemented trademarks, has a thicker grip than you would expect which makes it very comfortable and solid to hold. This gun shoots hard, and it shoots accurately. I just shot 36 rounds at a paper target with a 2.5 inch ring surrounding a 1 inch centre target. This was handheld with no support from 20 ft. back. The one inch ring was completely shredded, in fact it was only by subtracting the hits in the 2.5 inch ring that I was able to determine that 22 bb's hit the centre 1 inch ring. 10 more BB's were in the 2.5 inch ring, and there were 4 flyers the farthest of which was just over 3.5 inches out from centre. That's pretty accurate for a gun with less than a 4 inch barrel! The blowback is crisp, slide doesn't come all the way back but it retracts enough for a realistic sense of shooting and it locks back on the last shot. Things I would change. Make the magazine full metal instead of cutout around the CO2 cartridge for greater realism, white dots on sights front and back (although maybe Umarex are just being faithful to the original by omitting this), and ditch the plastic tab on the bottom of the magazine for a threaded plug and Allen key type arrangement, Would love to see Umarex come out with a higher end chromed model with wood hand grips as many of the original Beretta 84FS were produced this way. This gun is an excellent value, a very accurate shooter and makes a good addition to your collection.

Nice Beretta

I never really liked the look of the M92 Beretta over the Walters CP88's which I have the blued short barrel and competition nickel wood grip versions, so I never purchased one. But I am glad I purchased this little M84. It has a nice look to it and all the guns feature's work like the real one. At 99.00 dollars the price is right and allows people to build nice little collections with out busting the bank so to speak.D

Umarex Beretta M84FS 4.5 mm BB pistol

The Umarex Beretta M84FS was an instant ‘must have’ when was first shown by Michael on his “Shot Show Vegas 2014” report. His Table Top and Field Test Reviews strengthened my resolve to buy one. I finally purchased mine last December and have no regrets what-so-ever. Perfect size (for me), nice weight, and an excellent build and finish. Unfortunately, due to our crappy east coast weather, I wasn’t able to use it until well into the Spring. Have to admit that the trigger takes a little getting used to due to the way the BBs are fed into the chamber, as fully explained by Michael in his reviews. (Nothing like the “hair” trigger on the Tanfoglio Witness 1911:-) Mine also tends to shoot a little high and slightly to the right. On a hot sunny day (yes, we have actually had some of those) this pistol certainly seems to have a high velocity, especially for the first couple of magazines. Also, it is rather loud. The only negative thing about the 84FS for me was the CO2 tightening screw/tab arrangement, as it really detracted from the realistic look of the pistol. After some thought, I came up with the idea of replacing the existing screw/tab with a hex, or Allen, key driven set/grub screw, as used on some Cybergun products. A friend was able to remove the pin from the tab and remove the complete original screw assembly. This was replaced with a grub screw of suitable length that had the non-drive end filed down to provide a larger surface area for contact with the CO2 cylinder. Using the obligatory drop of Pelgunoil on the CO2 cylinder head, I had no problem obtaining a good seal without any hint of a gas leak. Should also mention that putting a drop of the same oil on the feed slide of the magazine does result in a smoother trigger pull. I have a few pictures of the conversion but obviously cannot attach them to this review. Maybe Michael will post them if any other owners are interested in converting their 84FS.
