He also may have had 'FTF,' (failure to fire) or 'pop-opens' upon firing because he wasnt snapping it closed with enough authority. Ask about these issues and get a straight answer from him.
A new, tight action needs a little breaking in for the latch to work right. The FTF is more problematic; if so, were they handloads or factory, did repeat hammer strikes work or wasnt he 'following through' with the trigger well enough? At worst it would be (likely) a 'transfer bar' issue, easily fixed.
That isnt a bad price if you want that caliber or dont want what he wants to trade for.
