Mine was due Jan 2023 so I went ahead and did it three weeks ago on-line and it went through.Here it is, § 400.00 section 10 subsection (d):
Note that the "will expire in less than one year" is preceded by an "or". My reading of this section says that anyone with a license that was issued 3 or more years prior to the day this law takes effect will have to recertify within one year.
My re-cert is due in December 2022, I was thinking of getting it done early to avoid having to attend 16 hours of classes that haven't even been defined yet (much less offered by any instructor) before the end of the year... but from what I think the law says, that's a no-go.
I hope the new Law gets repealed, but just in case I'm going to have my Handgun Safety and Hunter Safety Instructors credentials updated... While I do not support the Law or the premise of it, I am going to make preparations to instruct provided I'm allowed to.
