Hi JimHi!
I have been looking at a K-38 14-4 1977?
stansdds gave you a good answer for this.Were there any known production issues around this time?
I agree although I am no longer a regular shooter...I check fit and functionality on guns I receive, and other than minor finish issues, the BP era guns do not stand out as needing extra caution...There are those who complain about QC issues during the Bangor Punta years, but my experience with BP S&W revolvers has never exposed those alleged problems to me.
