Definitely Albacete knives are not to be plugged into gun barrels; the only doubt resides in sellers (or others) assumptions, whether being due to ignorance or for commercial reasons.
Whereas hunting bayonets, plug bayonets, bayonetas de taco, bayonetas de caça, are all correlative; whether you used them for hunting or in combat; whether you mount them in your gun when you have to parry a wounded game and you have no time for reloading or for military strategy in battle.
I guess (guess) wobbling was not much of an issue, as grip taper would be made for, or adjusted to, different barrels bore (caliber) opening, in a way to completely stick before meeting its swell; actually narrations exist in that they get so stuck that sometimes it demands for some (even mechanic) strength to take them out the barrel.
