Umarex Beretta Mod. 84 FS CO2 Blowback BB Pistol Table Top Review

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.

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.
Available in the: Canada Replica Airguns Store & US Replica Airguns Store.

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.
