Well just because Hargrove may have had it or if it was integrated into Maine's suit doesn't mean Wash would have taken it back.

Roughly four years passed since Recovery One. Wash may have not felt the need to take it back after the end of Season 13. Just because he could get it back doesn't mean he'd want to. Time passes, people change.

Also Wash could have it back, we don't know. He hasn't had a reason to use his EMP equipment in either Season 15 or 16.
