With notch and post sights, you can shoot precisely.
Also good for shooting for left-handers

The locking screw for the CO2 cartridge on the magazine is of poor quality. The rest of the weapon fits perfectly.

Great gun, although it was the only one of mine to break so far, but it was no problem to fix it.

Accuracy, for me one of the most accurate BB BlowBack pistols
all-metal, massive, really heavy, fits great in the hand
sophisticated safety system as in the original (it is possible to "decock" the weapon when it is loaded, it can be easily unloaded

Unfortunately, after about 200 shots the trigger mechanism broke, however, Balistas repaired it without any problem under warranty
The paint scratches very easily

Overall a good gun, heavy in the pocket, but the impression is excellent.

The pistol is well made, including plastic stock. The slide can be retracted by about 5cm. Blowback is strong and after firing the bullets the slide stays back like a live weapon. When the release lever is pressed, the slide slides down to the normal position. The safety is easily operated with the thumb of the right hand and also allows the firing pin to be closed without firing. The magazine is all-metal, very heavy, and the total weight of the gun is probably close to that of a live weapon. The overall impression would be excellent if it were not for the magazine...
I don't rate the shooting, I've only shot about 3 magazines so far and I'm out of bombs. The sights are solid and highlighted with white dots. Too bad it's not for pellets, then it wouldn't be a mistake.

Charging the magazine is difficult. The spring is quite hard and the feeder does not have a lock. In addition, it is completely drowned in the groove, so you can't pull it off with a fingernail and have to use some kind of steel tip. You can't feed the balls in the top of the groove, (as per the instructions), but in the bottom where there is a very small hole. I always have a lot of beads fall out because you have to hold the magazine, compress the spring and fill at the same time. This really fails and spoils the feel of the gun.
