Holy Gun achievement bugged?

[The King In Yellow]

I've looked through the other threads and tried everything, used the gun till empty on multiple different levels, tried a fresh save, uninstalled and reinstalled, I just can't get the achievement to pop. Anyone found a fix?

just tried it in Harbor level with no luck ! didn't switch guns until it was empty and finished the level.
guess it is glitched

I also didn't get the achievement after using the gun in Harbor, but I did get it later after finding it again on a different level.

Have done it in all three locations multiple times with no luck, will try uninstalling and see what happens.
were you in chapter select, new game+, normal run ?

It was a normal run. I believe it was the one in the level just before the second boss.
