dont just count the stuff beyond the shroud. the barrel would be everything beyond the trigger. it just might be inside the other workings.
Doesn't really matter since the weapon is too short to accomodate a long barrel inside the casing.
But since the description specifically states "a long-barreled blaster pistol", I'd say they mean on the outside of the casing, not inside.
uhhhh being a gunny long barrel refers to the length of the barrel. One does not say a colt long slide has a short barrel even though the barrel is entirely inside the slide. So I don't find your logic solid. Also based on what I am looking at above that gun is a foot long. Which is really long for a pistol. For comparison the DL-44 is much shorter at around 7 inches.
I still wouldn't describe that as "a long barreled pistol".
A large pistol, sure, but not with an emphasis on the barrel length when describing the looks of it.
"Long barrelled pistol" sounds like it has a visually long barrel to me.
Besides, the pistol you're showing there is hardly much longer than the DH 17 blaster pistol. So I certainly wouldn't describe it as a long barreled blaster because of that.
Sure, you could say that my choice wasn't longer either, but it sure does have a visually long barrel.
