I am very careful about clean & lube and gently opening and closing my doubles. I do,however, "baby" the top latch by holding it in open positon until gun is closed and then ease it closed. It became a part of my regular routine when shooting competatively and has carried over from there. I saw all kinds of crazy moves on the skeet fields ... from the Larry Woo swoop close to the G. Gilliam snap shut. I have never had a problem resulting from my "baby" close. It's pretty clear to me when a K80 is closed.

A Springer Spaniel, a 6# double and a fair day to hunt.
