A couple of weeks ago I mentioned in another thread my concern with push-off in a K-22 Masterpiece (pre-17) that I had just acquired. Rather than resurrect that thread, which was mostly NOT about that issue, I thought I'd just weigh in here with a new message to say that the situation has been fixed. With a six-inch ceramic stone from Brownell's, I first squared up the single-action notch on the hammer, and then using the approved technique shown here in the FAQs, I dressed up the end of the mating trigger surface.
Success! When I put the gun back together, the trigger pull had increased from a sketchy two pounds to a much more comfortable (for me) three pounds, and the push-off problem was vastly improved. If I really put some thumb into the back of the hammer, I can make it break loose, but the sensitive initial condition has been resolved.
I know I have probably taken off all the surface hardening. I will order some kasenite from Brownell's and give the worked surfaces of these parts a hardening treatment. It's not like I am going to be putting thousands of rounds a year through this gun, but I'd like to have it as solid as possible so I don't have to go back through this stoning process again.
Thanks to all of you who encouraged me in undertaking this effort. You were right! It is a pretty simple process. You just need to take your time and resist the temptation to do as much stoning as you think you may have to.
