At the Reno Show in April I found an early 1980's M-18, like new, target hammer and trigger, std magna grips. Unfortunately no box. I paid $650 and Frankly didn't feel it was out of line.
I have found, along with my three other S&W Seeking Buddies...that truly LIKE NEW or UNFIRED older K-22's and M-18's are getting rarer and rarer.
Paying $600 or $700 for a like new K-22 or M-18 VERSUS paying a GRAND for a new lock/MIM gun...No contest with me.
