Yes, there is some spitting, more with some ammo and less with others. It's consistent enough that I simply couldn't enjoy that gun and had to sell it. A shame, because it was a terrific shooter, very accurate, totally reliable and with a feel of quality.
As Metalbender stated, you are essentially shooting a pistol with a non-enclosed slide while holding it right in front of your face. If you have access to a handgun of that description, try it for yourself in that position and see what you think. Eye protection is a must with most guns just in case something goes wrong. In this case, it will be especially important. One magazine through it and you'll see why.
