Personally, I'm okay with seeing a "Training Grenadelauncher EG II" and a "Training Grenadelauncher BL II", but I am against having any STUN Grenadelaunchers. As Sunrui said, the benefits of using training weapons is that they have 0 weight, and having a Training variant of the STUN type of Grenadelauncher would be detrimental to fair game play, since you could have literally people spamming it for the stun effect. (Perfectly paired with a Flamethrower). Even with your suggestion of giving it the same stats as a normal STUN grenadelauncher, the main benefit of a training weapon is it's weightlessness which people would easily take advantage of.
