Vladof handguns need update?

the case is: among 50+ hours of playing I’ve been getting 0 (zero) truly elemental Creech pistols. I mean, they had elements listed, just wouldn’t use these: if they had Taser accessory it would use the element, the primary fire mode, never. So I thought it’s a Vladof feature.

And now, after the recent update, when I’ve picked up some Kot-s I get not only handguns that shoot elements but also double element ones. And I thought the update has changed something. Well, no: shock Creech-es still shoot regular bullets and use element only with taser.

Is this the feature or a bug?
