Ignition switch hard to turn off

97 Ram 1500/5.2L 78k miles. Lately (last couple months or so) it's becoming increasingly difficult to turn the ignition key to the full off position where I can remove the key. I find pulling the shift lever harder into Park helps. Knowing others may have had this problem I thought I'd bring this to the group and ask if anyone knows how to deal with this. (yes, I know not to spray WD40 into the lock or shift column)

Suggestions appreciated.
