Umarex HDR50 Revolver - Home Defense

This is the Umarex HDR50 Revolver, A superb engineering feat by UMAREX

This is to come up w/ something cost effective, available over the counter for the everyday people like me and you, yet also, unlike the usual 4.5mm gas guns, this revolver sports a .50 calibre (12.7mm), about 2.8x greater in calibre size, which equates to weighter rounds (the mainstay of polymer solids this gun uses, are 24gr, compared to the 5.4gr nickel-clad steel shot that your typical CO2 smoothbore pistol uses). 

This revolver is reminiscent to some of the new .44 MAGNUM lineups that TAURUS have been bringing out in recent years, but with a massive compensator under the barrel. Its whole of the body is injection moulded polymer, which lends to this revolver's low price tag, also ensuring lower weight and durability of its colour and likewise, resistance to colour removal, for example, if you bump the revolver, then the finish won't come off the way anodizing comes off of aluminium.

The body is a two-piece clamp shell, coupled by an assortment of M2 self-tap button head phillips-drive screws that are painted black. 

The top section over the barrel has been slotted out in rounded-edge rectangular shapes, which on a firearm, would serve as heat dispersion from the barrel. As previously mentioned, there is a beefy compensator under the barrel, which adds front-end weight and acts to mitigate felt recoil when firing this revolver. Your run-of-the-mill ammunition won't, as a result, cause much recoil.

This revolver weighs in at 724 grams, making it really wieldy and woman-friendly as well, despite its large and imposing "big iron" appearance. The handle is nice and full sized, featuring three slopes that would correspond w/ your little, ring and middle finger respectively. There are vertical stippled panels on the sides of the handle, also a horizontal stippled panel at the nape of the handle.

This does improve grip traction. The trigger guard is generous and the trigger itself, is a GLOCK "SAFE ACTION®" imitation type, that we really like - that auxiliary trigger blade has a crisp, hair-fine spring load to it, that takes up just about no effort to depress, whereafter, the primary trigger starts to break.

It has a bit of a double-action heftiness to it and a bit of deliberate force needs to be applied, before yielding. At that moment, your magazine will index and simultaneously, your valve will open for a split of a second. Just mind though - as that trigger breaks, the entirety of the gun flinches. Try to minimize this - the standard magazines are all designed like this, in order to ensure that the magazine indexes properly. We do urge new owners of this revolver to control this as best as possible, to ensure maximum accuracy.

The magazine likewise is a 6 shot type, in .50 calibre w/ removable alloy ratchet core. The rear of the loading holes for this magazine is chamfered to allow easier loading - we also recommend loading up the magazine from behind, not the fore, as it is trickier and because the magazine is polymer, the holes can end up boarding out faster with repeat use this way, due to increased friction. Not that it is a real problem, but if you like keeping your equipment in its original condition for as long as possible, we recommend the above.

The Umarex HDR50 Revolver uses 1x 12g CO2 capsule, which is inserted upside-down into the handle (w/ the nozzle pointed downward), whereafter the bump cap is threaded back up. At this time, this revolver is not charged / pressurized, and likewise, will not shoot / discharge pressure when the trigger is pulled. You'll need to bump the cap by the orange corona sticker at the bottom, which will pressurize the marker. This will be indicated by the nub at the back of the revolver (where the hammer would normally be situated on a revolver), which will be protruded. This way, you know if the marker is pressurized. If not pressurized, then this nub will be in its reset position.

To degas this marker manually, you'll need to depress the nub at the top, either with your finger, but if it proves too tense, you might need to use the supplied allen key as a push-assist, to bleed the gas out.

At 20 meters, you can expect to get a six shot grouping into a 1.5kg RICOFFEE tin on average w/ the 24gr PVC Nylon shot. Accurate enough to hit a stationary target centre mass. At that distance, the shot will readily penetrate that same empty coffee tin. On human tissue, it will leave a painful .50 calibre crater penetrating the first few dermal layers. As the distance to the target closes, so does the grouping and likewise, the damage skyrockets. However, so does the threat level, if facing an attacker armed w/ a melee weapon.

You can keep it under your car seat, in the glove box, maybe under the steering rack if you wanted to. The problem with waistband carry, is that the bump cap might be vulnerable to getting knocked / bumped unintentionally. However, alot of people do IWB carry this w/out issue. We just don't really recommend underarm carry if you haven't previously done so.
