Comparison of the DEFENDER .50, versus the HDR50;
We like this revolver in terms of ergonomy a little more, due to its narrower profile and slightly less weighted feel to it. It certainly does feel a lot more comfortable to brandish. This revolver features no extraneous bottom cap that otherwise makes for an eyesore and appears more flush around the base of the handle. However, we discovered that there is no bump cap / fast gas piercing system, so you'll have to give the screw head at the bottom, a thorough crank / full turn when you want to gas the marker up. This base cap likewise, does not have any O-ring on it, which is a plus, though to depressurize the marker, you'll need to push the pin above the nape of the handle in to degas, whereafter only, the pressurized receptacle can be removed. However, this aforementioned method, can actually result in faster reloads, once you get used to it.
The magazine release is a bit of a bugger - the magazine retaining pin does not have a forwardly retaining position like on the HDR50, so you'll have to hold the hold that pin back manually against the spring tension in order to remove the magazine.
There is no double blade trigger safety and no hitched second stage trigger take-up, which allows for more rapid firing and also, less trigger jump, meaning, less user-induced recoiling. We actually prefer the trigger weight on this marker.
This revolver does feature a handy red fibre optic sight on top and the revolver does have an actual / proper safety mounted on the trigger.
The base cap here does not require an allen key or any tool for that matter. The gas can be pressurized, just by rotating the cap with your bare hand, which is nice, as you don't need an additional 3D printed accessory for assistance.
Due to the added barrel length, you also have alot more under-barrel mounting area to work with, for fitting larger optical accessories. Something that may have been slightly oversized for the HDR50, will now fit fine on this marker.
As you might've guessed by this point - this marker is upgradable for power, just like the HDR50 - feel free to have a look;

Product description
A new effective way to defend your personal and property by shooting .50 caliber rubber bullets.
Caliber .50
The .50 caliber (12.7mm) is an ideal compromise between practicality and efficiency. It offers suitable properties for self-defense, as the projectile can be heavier and larger. In addition, it is a very widespread caliber, so many types of ammunition are available for it.
Metal trigger and manual safety
The Defender pleases with a metal trigger with a pleasant operation and a reliable manual safety in the trigger, which we know from other models from the SPA brand.
6-round magazine
The type of wreath tray used is one of the most reliable in its category, as there is no feeder or spring. In addition, the magazine can be used for ammunition with an asymmetrical shape, such as Precision. For self-defense, a combination of several projectiles in a magazine - for example, rubber-metal and pepper filling - is best suited.
Puncture of the cartridge
Guns for 12g CO2 cartridges have their disadvantage - it is not advisable to leave a punched cartridge in them for a longer period of time (more than 3 days). At the same time, however, it is important for self-defense that the cartridge can be penetrated (activated) as quickly as possible. The CP300 Defender uses a classic reliable screw cap, but it is designed to pierce the cartridge as quickly as possible. All you have to do is insert the cartridge into the handle and tighten the cap slightly with feeling. To quickly pierce the cartridge, it is usually enough to tighten the cap with one turn. We recommend trying this procedure to get a feel for it.
22mm RIS rails
The revolver has an upper and lower 22mm RIS rail, so you can equip it with a flashlight, laser, or even a collimator if the original sights are not enough for you.
Power version up to 11J up to 135 m/s.
The internal structure of the weapon consists of a metal frame, which is then covered with a polymer to maintain low weight due to its considerable dimensions.
The weapon technique is designed to be as easy to operate as possible and uses a proven solution to guarantee the highest possible reliability of the weapon.
The SPA Defender revolver uses a 12g CO2 cartridge as a drive, which is inserted into the handle.
In the case of the SPA CP300 Defender revolver, the trigger mechanism has a DAO - Double Action Only mode. So all you have to do is pull the trigger to fire.
Rubber Ball ammunition is inserted into a separate wreath magazine that can hold 6 of these BBs. There are several types of ammunition of this caliber available.
The SPA Defender air revolver does not have to be used only for defensive shooting. Although it is not for competitive target shooting, it can also handle cans or other practice targets well.
Ammunition, accessories for the operation and maintenance of this weapon can be found below this description in the section we recommend buying.
