Umarex Magnum Research Desert Eagle


de5There was a lot of interest in the Umarex Desert Eagle when it launched in 2005 – it was the first blowback pellet shooter since Crosman stopped making the Model 451 (a Colt 1911 replica) in 1970.  It’s certainly a striking pistol – it’s over two inches longer than the Umarex Colt 1911, and despite being mainly plastic construction, it weighs a little more too.  It also has a reputation for fearsome power (and CO2 consumption), but is it actually any good?

Real steel background

The Desert Eagle is a large frame semi-automatic pistol which uses a multi-lug rotary bolt similar to that found in the AR-15 rifle.  Unlike most recoil operated semi-auto pistols the Desert Eagle is gas operated – a small valve is used to channel gases to move the rear part of the slide.  Only the rear and sides of the slide move during operation. The pistol was designed and developed by Magnum Research Inc. (MRI) based in Minneapolis, USA (now wholly owned by US gunmaker Kahr Arms, producer of the famous Thompson submachine gun).  The Desert Eagle was initially conceived as a semi-auto pistol capable of using .357 Magnum ammunition – it was originally to be called the Eagle 357.  The MK1 Desert Eagle was launched in 1983 and until 1995 was manufactured in Israel on behalf of MRI by Israel Military Industries (IMI).  From 1995 manufacturing switched to a US contractor before reverting back to IMI (who were later renamed Israel Weapon Industries) in 1998.  In 2009 manufacturing was switched to MRIs own plant in Minnesota, USA and all Desert Eagles are currently made in the US.

The current Desert Eagle is the Mark XIX, mainly distinguished from earlier versions by having a fixed picatinny rail on top of the barrel.  It’s available in a variety of finishes including black, brushed chrome or titanium gold and is provided with fixed or adjustable open sights.  However, the non-moving front part of the upper body allows a range of aftermarket red-dot or telescopic sights to be fitted.  The Mark XIX is chambered for .357 Magnum, .44 Magnum, and .50AE (Action Express) rounds and barrels are interchangeable.

Sadly, the idea that police, military or special forces use the Desert Eagle is a Hollywood myth.  Massive recoil, blinding muzzle flash and deafening noise aren’t ideal characteristics for a police or military weapon and as for concealed carry, well, let’s not be silly here.  Add to this that you could carry two Glock 17s and spare ammunition and this would still weigh less than a Desert Eagle and it’s no surprise that this is principally a target shooting pistol.  In the US the Desert Eagle is also used for hunting, mainly using the .50AE round.  If you need to stop a charging grizzly bear with a single shot, I guess this is probably the pistol for you.

Don’t believe me about that recoil?  The video above shows a woman firing a single shot with her husband’s .50AE Desert Eagle.

The Umarex Magnum Research Desert Eagle

The Umarex Magnum Research Desert Eagle is a replica of the Desert Eagle Mark XIX and is constructed mainly of plastic with metal internal parts.  This a blowback pistol where the moving slide cocks the hammer as it recoils.  CO2 is stored inside the grip and accessed and pierced by turning a slotted brass threaded plug in the base of the grip.  No slide lock or release is provided and the slide does not lock back on empty. An ambidextrous, slide mounted manual safety is provided.

Pellets are retained in the familiar Umarex eight-shot rotary pellet holder and the front part of the barrel is released for loading by operating what looks like the slide release catch on the left of the frame.  The magazine release catch and takedown lever are moulded in place and have no function.  A standard Weaver style rail is moulded-in above the barrel and an additional removable accessory rail is provided which can be fitted below the barrel.


Packaging and presentation  2.5/5


The Umarex Desert Eagle comes in a sturdy cardboard box and is provided with a single, eight-shot rotary pellet holder, a tool for tightening the brass CO2 plug, an additional accessory rail which can be fitted below the barrel and a brief user manual.  It’s perfectly acceptable packaging, but not up to the standard of the hard case provided with some other Umarex pellet shooters.


Visual accuracy  8/10

The overall size and profile of the Umarex Desert Eagle is very close to that of the original Mark XIX. However, there are a number of minor differences.  There is additional grooving on the barrel of the original and the shape and location of the slide release is different on the replica, as is the left grip.  The trigger is also mounted further forward on the replica and the characteristic projection of the magazine beyond the base of the grip isn’t replicated.  Markings on the left of the replica are good, lacking only the calibre on the nose of the barrel.  Markings on the right of the replica provide safety information, some printed in highly visible white text.


White safety text on the right side. The moulded in place takedown lever isn’t terribly convincing.

The shape and location of the ambidextrous slide mounted manual safety is accurately replicated though the takedown lever on the right of the frame is very obviously moulded in place.  However, the most notable difference isn’t noticeable in pictures – most of the Umarex Desert Eagle is constructed of plastic, and this is very evident when you actually handle one of these.  Some manufacturers (Tanaka and Tokyo Marui, for example) seem to be able to make plastic replica pistols which look like metal.  This one is made of plastic (albeit very good quality plastic) and it looks like it.  There are also obvious moulding seams too – on top of the slide and barrel for example.

The weight of this replica is good at over 2.4 pounds but isn’t even close to the 4½ pounds (unloaded) of the original.  Overall a reasonably close visual replica, but the plastic construction is very evident.

Functional accuracy  10/15

The Umarex Desert Eagle is the only Umarex blowback replica to use the rotary eight shot pellet holder.  The rear and sides of the slide move during blowback, as on the original though the slide only moves back around 1″ during blowback, compared to well over 2″ on the original.  The moving slide also doesn’t cue up the next pellet for shooting, so this isn’t true semi-auto action.  The rotary pellet holder revolves via the trigger, regardless of slide action.  What looks like a slide release catch is used to release the barrel to move forward and allow loading of the pellet holder.  The ambidextrous slide mounted safety catch works as it does on the original.

There is no drop-out magazine – CO2 is retained within the grip and accessed via a threaded brass plug which is tightened and loosened by using the supplied tool (though a coin can also be used).

Shooting  37/40

I have seen a variety of conflicting reports on shooting with the Umarex Desert Eagle.  Some people complain about a lack of power while others praise the gun’s extreme power.  My experience with this replica seems to be somewhere in the middle but bear in mind that I have only owned and tested a single example of this pistol.


To prepare the Desert Eagle for shooting you must first remove the brass plug from the base of the grip, insert CO2 and use the supplied tool to tighten the plug until the CO2 pierces.  Then, operate the slide catch on the left to allow the front part of the barrel to move forward and remove the rotary pellet holder. Then load pellets into the rotary holder (being careful to tamp them down to avoid jamming), re-insert the holder and push the front part of the barrel to the rear until it locks. Do be careful to keep your hand away from the muzzle as you push the front part of the barrel to the rear.


The rotary pellet holder simply drops into the space between the rear of the barrel and the front of the slide.

The first shot can be fired in double action or you can retract the slide to cock the hammer or manually cock the hammer for single action.  The first thing you’ll notice when you’re ready to shoot is the length of trigger pull even in single action.  There is around 15mm of movement before the pistol shoots.  This is because pulling the trigger also rotates the rotary pellet holder to index the next pellet.  You can clearly feel the mechanism working as you pull the trigger back.  In single action it’s not a particularly heavy pull, but it is long and a little crunchy and the release point isn’t especially clear.  It’s quite different to the trigger on, for example, other Umarex pellet shooters such as the Colt 1911 or Walther CP88.  In those pistols, cocking the hammer also rotates the pellet holder, so the trigger pull tends to be short and crisp in single action.  On the Desert Eagle, cocking the hammer (either manually or using blowback) doesn’t rotate the pellet holder.

When you shoot, the first thing you’ll notice is the sound – this is LOUD.  It has a unique sharp crack, which sounds a lot like a .22 rimfire pistol and it’s notably louder than most replicas.  Then you’ll notice the recoil. The slide may be made of plastic, but it obviously has good weight and provides sharp, snappy recoil effect.  Then you’ll notice that you’re shooting tight groups, pretty close to the point of aim.  This is a very accurate pistol – as good if not better than most of the other Umarex pellet shooters.  It also shoots with a fair amount of power – on a fairly chilly day I saw an average of 420fps with my Desert Eagle (as a comparison, in similar temperatures my Umarex Colt 1911 gave around 370fps).  In the unofficial catfood tin test (those cats had to be good for something!) most pellet shooting replicas I have owned were capable of piercing the near side but only dented the far side of the tin, leaving the flattened pellet inside.  The Desert Eagle consistently shot through both sides of the can and left the pellet embedded in the backing board.


Eight shots, six yards, rested.  Outer circle diameter is 6″

Groups free standing were around 1¼” – 1½”, though if rested this came down to under 1″.  The Desert Eagle also had more range than most of my pistols; freestanding it was grouping around 2½” at 25 feet and around 4″ at 10m.  At these ranges it was hitting the target hard and without noticeable pellet drop.  I also tried it at 20m, and at that range it was still hitting the target hard though accuracy wasn’t great (though this was probably down to my elderly eyesight and using open sights).  Many of my replica pistols aren’t even capable of consistently hitting a 6″ target at this range.

There are two drawbacks to shooting.  First is the size of the pistol.  It’s big – the first time you pick one up, it feels like handling a prop from Land of the Giants.  The grip is broad as well as long, and it never felt as comfortable as shooting (for example) a Colt 1911 replica to me.  If you have small hands or you like to shoot single-handed, this may be an issue.  Though it has to be said that, despite its size, this replica actually does have good balance.

The second issue is CO2 usage.  I could generally got around 28 – 30 shots before power started to drop noticeably (I generally get around double this in other Umarex pellet shooters).  This means I was getting only three full pellet holders worth of shooting before I had to replace the CO2 (otherwise it was necessary to re-load the CO2 when I was half way through shooting the fourth batch of eight shots).  I suppose that’s the price you pay for that strong blowback action.  On occasion, the slide would give a sort of double stutter (though only one shot was fired) as CO2 pressure dropped.  As the slide doesn’t lock back on empty, it’s also easy to lose count of the number of pellets you have fired and find yourself shooting just air.


The sights seem well set up for shooting at six and ten yards – at six yards the point of impact was around ½” above the point of aim and at 10 yards it shot precisely to the point of aim.  I also tried mine with a red-dot sight and that worked very well indeed, allowing 1″ groups at ten yards even free standing.  This is one of the very few replica air pistols I’d be tempted to try with telescopic sights.  With a decent scope, I suspect that this might be capable of impressive accuracy at ranges well beyond those most air pistols can achieve.

Quality and reliability  12/15

Like most Umarex pistols, this appears to be very well made.  There are no rattles from the slide and blowback action is crisp and precise.  Although made principally of plastic, this seems to be very high quality material which is strong and durable.  Even the trigger is plastic, though the hammer is metal.  Because there is no paint, the Desert Eagle is almost completely impervious to minor scuffs and scratches.


I am aware of owners of Umarex Desert Eagles who have complained that the sides of the slide can distort with use and I have seen one or two complaints about failing safety catches.  I had no such issues with my Desert Eagle, and overall this seems to be as high quality and reliable as most Umarex pellet shooters.  However, if you’re considering a used example, do remember that early examples are now over ten years old and will probably be suffering from seal degradation and general wear and tear.

Overall Impression  12/15

When I first received my Desert Eagle, I was a little disappointed.  The weight is good (though not close to the original) but this very evidently a plastic pistol.  For me at least, it just doesn’t quite have the quality feel of other metal Umarex replicas such as the S&W 586/686 or the Walther CP88.  However, mine was a very fine shooter indeed which made up for my initial doubts.


My biggest gripe was the sheer size of this pistol.  I have average to large hands, but it still felt unwieldy and one-handed shooting was difficult.  You can’t blame Umarex for this – the grip and overall size are accurately copied from the original, which MRI claim has good ergonomic design.  This pistol may suit you if you have Andre the Giant sized hands, but those with smaller paws may want to try handling before they buy.


The Umarex Desert Eagle is a very satisfying shooter – it’s loud, powerful and accurate with decent recoil effect.  It’s also capable of hitting targets accurately at ranges where many other replicas are running out of puff.  However, it’s a large and unwieldy pistol which has a very long single action trigger pull and it does go through CO2 at a higher than average rate.


You can add accessories to the Umarex Desert Eagle, but remember that this will add weight to an already heavy replica.

For me though, the biggest disadvantage is its obvious plastic construction.  It’s ironic that a replica as accurate and powerful as this looks more toy-like than many much less powerful replica pistols.  However, if you can put up with those looks, if you have big hands and especially if you’re willing to fit a red-dot or telescopic sight, you’ll have a very fine action shooting target pistol indeed.

Total score: 81.5/100

One thought on “Umarex Magnum Research Desert Eagle

  1. This Pellet gun sucks I have owned three and they all broke because the plastic slide sucks and UMAREX uses inferior manufacturing components. If it were made out of metal or better materials this PELLET Gun would be indestructible.
